How to Store Batteries

The recommended storage temperature for most batteries is 15°C (59°F); the extreme allowable temperature is –40°C to 50°C (–40°C to 122°F) for most chemistries. ASUS A2 battery While lead acid must always be kept at full charge during storage, nickel- and lithium-based chemistries should be stored at around a 40 percent state-of-charge (SoC). This level minimizes age-related capacity loss while keeping the battery in operating condition and allowing self-discharge. ASUS M2 battery
Finding the 40 percent SoC level is difficult because the open circuit voltage (OCV) of batteries does not lend itself well to state-of-charge estimations. For lack of better methods, voltage is nevertheless used as a rough fuel gauge indicator. The SoC of Li-ion is roughly 50 percent at 3.80V/cell and 40 percent at 3.75V/cell. Allow Li-ion to rest 90 minutes after charge or discharge before taking the voltage reading to get equilibrium. ASUS M3 battery
SoC on nickel-based batteries is especially difficult to measure. A flat discharge curve, agitation after charge and discharge, and voltage change on temperature contribute to the fluctuations. Since no other estimation tool exists that is practical, and the charge level for storage is not all too critical for this chemistry, simply apply some charge if the battery is empty, and then make sure that the battery is kept in a cool and dry storage. ASUS M5 battery
Storage will always cause batteries to age. Low temperature and partial SoC only slow the effect. Table 1 illustrates the recoverable capacity of lithium- and nickel-based batteries at various temperatures and charge levels over one year. The recovered capacity is defined as the available battery capacity after storage with a full charge.ASUS M6 battery

Table 1: Estimated recoverable capacity when storing a battery for one year
Elevated temperature hastens permanent capacity loss. Depending on battery type, lithium-ion is also sensitive to charge levels.
Lithium-ion batteries are often exposed to unfavorable temperatures, and these include leaving a cell phone in the hot sun or operating a laptop on the power grid. ASUS S5 battery Elevated temperature and allowing the battery to sit at the maximum charge voltage for expended periods of time explains the shorter than expected battery life. Elevated temperature and excessive overcharge also stresses lead and nickel-based batteries. All batteries must have the ability to relax after charged, even when kept on float or trickle charge. ASUS W3V battery
Nickel-metal-hydride can be stored for about three years. The capacity drop that occurs during storage can partially be reversed with priming. Nickel-cadmium stores well, even if the terminal voltage falls to zero volts. Field tests done by the US Air Force revealed that NiCd stored for five years still performed well after priming cycles. It is believed that priming becomes necessary if the voltage drops below 1V/cell. Primary alkaline and lithium batteries can be stored for up to 10 years with minimal capacity loss. ASUS W5V battery
You can store a sealed lead acid battery for up to two years. Since all batteries gradually self-discharge over time, it is important to check the voltage and/or specific gravity, and then apply a charge when the battery falls to 70 percent state-of-charge. This is typically the case at 2.07V/cell or 12.42V for a 12V pack. (The specific gravity at 70 percent charge is roughly 1.218.) ASUS V6V battery Some lead acid batteries may have different readings and it is best to check the manufacturer's instruction manual. Low charge induces sulfation, an oxidation layer on the negative plate that inhibits current flow. Topping charge and/or cycling may restore some of the capacity losses in the early stages of sulfation.
Sulfation may prevent charging small sealed lead acid cells, such as the Cyclone by Hawker, after prolonged storage. ASUS Z3A battery If seemingly inactive, these batteries can often be reactivated by applying a higher than normal voltage. At first, the cell voltage under charge may go up to 5V and absorb only a small amount of current. Within two hours or so, the charging current converts the large sulfate crystals into active material, the cell resistance drops and the charge voltage gradually normalizes, and at a voltage of 2.10–2.40V the cell is able to accept a normal charge. ASUS Z33A battery To prevent damage, set the current limit to a very low level. Do not attempt to perform this service if the power supply does not allow setting current limiting. Read about Charging with a Power Supply.
Simple Guidelines for Storing Batteries ASUS Z71V battery

Primary batteries store well. Alkaline and primary lithium batteries can be stored for 10 years with moderate loss capacity.

Remove battery from the equipment and store in a dry and cool place.

Avoid freezing. Batteries freeze more easily if in discharged state. ASUS A1 battery

Charge lead acid before storing and monitor the voltage or specific gravity frequently; apply a boost if below 2.10V/cell or an SG below 1.225.

Nickel-based batteries can be stored for five years and longer, even at zero voltage; prime before use.

Lithium-ion must be stored in a charged state, ideally 40 percent. This assures that the battery will not drop below 2.50V/cell with self-discharge and fall asleep. ASUS F7 battery

Discard Li-ion if the voltage has stayed below 2.00/V/cell for more than a week.
Caution:
When charging an SLA with over-voltage, current limiting must be applied to protect the battery. Always set the current limit to the lowest practical setting and observe the battery voltage and temperature during charge. Asus F7000 battery
In case of rupture, leaking electrolyte or any other cause of exposure to the electrolyte, flush with water immediately. If eye exposure occurs, flush with water for 15 minutes and consult a physician immediately.
Wear approved gloves when touching electrolyte, lead and cadmium. On exposure to skin, flush with water immediately. Asus F74 battery

Can your laptop battery be overcharged?
Most laptops today use lithium Ion (Li-ion) batteries. Overcharging Li-ion batteries is not a problem and does not affect the battery life span. These batteries can be charged 300 to 500 times, and they have an internal circuit to stop the charging process at full charge. Asus F7400 battery The control system prevents overcharging, which can cause the lithium ion battery to overheat and potentially burn. This is why the Li-ion batteries are more expensive. The only way for the Li-ion battery to overcharge is if the charging system malfunctions, and then the battery will heat up while in the charger. Asus F7400B battery If you don't plan to use your laptop for long period of time, you can extend the life of your lithium ion laptop battery by storing it with a 50 percent charge. A fully discharged battery left for a long period of time will lose its charging capacity. Fully charged batteries discharge when they are left unused, and will lose effectiveness. Asus F74B battery This is why it is recommended to discharge a Li-ion battery until it is almost out before shutting down. Running a Li-ion battery down completely will diminish capacity. Keep the battery in a cool place and do not store your computer for a long period of time while it is fully charged. Asus F7B battery
Older laptops use Nickel-cadmium (Ni-Cd) and Nickel Metal Hydride (Ni-MH) batteries. They require more maintenance than Lithium Ion batteries. They must be fully discharged and then fully recharged so that they don't lose battery life. These batteries can be overcharged only if they go through too many cycles of charging and discharging, which reduces their effectiveness and capacity. Asus L7 battery It is better to charge all batteries fully before use; then use on battery power until the optimum level for each battery type is reached, before recharging.

How to Keep Your Dell Laptop From Overheating
In order to provide you with a compact computer, Dell manufacturers design laptops with all the internal components placed closely together. Asus L7000 battery Because of this crowding, Dell laptops have a tendency to overheat faster than desktop computers. There are a number of interior devices to help counteract the overheating, such as fans and heat pipes. But after a long session on the laptop, it will eventually heat up . Asus L7000B battery There are tips and tools that you can use to keep your laptop cool. Read the points listed below and learn about how to keep your Dell laptop from overheating.
Laptop Maintenance There are several devices in your Dell laptop that work to prevent overheating. Heat sinks, air vents and fans are all installed within the notebook to dissipate hot air and cool off the system when it's operating for extended periods of time. Asus L7000C battery If you find that your laptop is overheating too quickly or getting excessively hot, you may want to take your computer in for maintenance. Have a professional inspect the cooling systems. You may just need a cleaning to clear away any dust or debris that could be blocking proper airflow. Alternatively, you may require a repair or replacement to one of your cooling system parts . Asus L7000D battery
Cooling Chill Mat Dell has created an accessory to prevent your laptop from overheating. The Cooling Chill Mat is a part that you can attach to the bottom of your computer. The mat is powered through your computer's USB port so no additional heat is produced. With the help of two fans, the mat keeps your computer's interior from heat damage and your lap from getting hot . Asus L7000E battery
BIOS Update Check on the Dell Web site to see if your computer's model has a BIOS update available. Often simply updating your computer's BIOS with a newer version will improve the notebook's fan efficiency. Be aware that installing the BIOS upgrade may be difficult and if you're not computer savvy, you may want professional help with installing the update Asus L7000G battery .

How to Know when Your Computer Battery is Dead
All personal computers have a small battery on the motherboard that provides power to the Complementary Metal Oxide Semiconductor (CMOS) chip, hence the name CMOS battery. The chip has the information about all the system's configuration, such as the hard disk, date and time, etc. It provides power even when the computer is off and allows the CMOS to save all the settings Asus L7000H battery. You can expect the CMOS battery to last for up to five years. The more your computer is used, the longer the battery will last. How do you know that your CMOS battery is dying? Here are some tell-tale signs that your battery is dying:
Invalid configuration will appear on your screen.
Run Setup appears on your screen.
Press F1 to continue appears on your screen.
Invalid drive specification appears on the screen after you've pressed F1.
Clock Error or Clock Message appears on your screen.
The clock on the computer loses time.
The computer is constantly showing the wrong date. Asus L7200 battery
Should you experience any of these symptoms, it's time to change the battery in your computer. If you don't change the battery, the battery will die. Your battery is dead when your screen is blank and you have thus lost your CMOS memory .

6 Easy Ways to Keep Your Computer Cool Without Using Electricity
Keeping your computer cool is important to its well-being and longevity. I only mention this, because the heat is on, not in some cheesy Glenn Frey way. Asus L7300 battery It's actually getting hotter as the Earth rotates us into summer.
As the temperature rises, your computer might be feeling the sting. Maybe you can hear its little fan chugging away. Your computer might even be hot to the touch. How can we cool our computers without adding more strain to our often overtaxed energy grid?
5 Easy Ways to Keep Your Computer Cool Without Using Electricity Asus L7B battery
1. Clean Your Computer
Your fan will work better if it is clean. It's just a good idea to clean your computer regularly with a reusable brush or a rag lightly dampened by rubbing alcohol. It'll extend the life of your machine. Stay away from canned air. Asus L7C battery
2. Cut the Clutter
If you have a messy desk, I won't judge you, but you need to clear all those papers and envelopes away from your from your computer's exhaust port.
3. Relocate Your Computer Asus L7D battery
Move your computer if it is in direct sunlight. Also, if your computer is up against a wall, move it a few inches away from the wall to allow for some air flow.
4. Keep Furry Pets Out of the Office
Pet hair can get into your computer and clog up the fan. Keep pets out of your office, turtles are the obvious exception. Asus L7E battery
5. Don't Remove the Case
Some people remove the case in order to make the computer cooler. It doesn't seem to have much of an effect unless you are running a fan over the open case.

Choose an Energy-Efficient Power Supply
While power-supply units (PSUs) have not traditionally been power savers, a 2006 white paper by two Google data-center designers noted that redesigning industry-standard PSUs could yield potentially huge energy savings. Asus L7G battery Installing redesigned power supplies in 100 million desktop PCs that run eight hours a day, for instance, would save 40 billion kilowatt-hours over three years, according to the paper-that's more than $5 billion at California's energy rates.
While Google's efficiency effort is theoretical at best, an initiative launched by utility companies and energy-efficiency organizations has resulted in real-world energy-saving PSUs. Asus L7H battery Known as the 80 Plus program, the voluntary certification program aims to make power supplies at least 80 percent energy-efficient. Many PSUs currently max out at only 60 percent, a result of their inefficiency in converting high-voltage AC power from the wall socket to low-voltage DC power for your PC. ASUS L1 battery And because these energy-efficient PSUs aren't overindulging on heat-generating energy, they can also eliminate the need for a fan, resulting in a quieter, more-reliable PC. Roughly 70 designs from almost 20 manufacturers now bear the 80 Plus label. A typical 80 Plus-certified option is the EarthWatts PSU from Antec, which is available in three models: 380-watt, 430-watt, and 500-watt. It features a universal input (which accepts line voltages from 100 to 240 volts AC), Serial ATA and PCI Express power connectors, and compliance with the ATX 12V standard. The built-in 80mm cooling fan is rated for low-noise operation. ASUS L7 battery
Another alternative is Cosair's VX450W and VX550W, both of which support Energy Star 4.0 standards and are rated for 80 percent or more energy efficiency under a wide variety of loading conditions. They're available in 450-watt and 550-watt models.

Save Energy Effortlessly with SetPower for Personalized PC Power Management ASUS L8 battery
There are loads of ways to make your computer greener, and one of the most important is managing its energy consumption when not in use. Ideally, your computer would be turned off whenever you aren't using it, but practically, that just doesn't happen. We often don't want to shut down our computer when leaving for a meeting that will last a few hours, or we get distracted and leave it on over night. ASUS M1 battery There are quite a few options for downloads that turn your PC into an energy sipper, but typically they aren't detailed in their setting options. If you'd like a power management system that is specific to your schedule, there's a new solution that could help you out.
Personalize Your PC Power Management ASUS M5N battery
SetPower is a free download that lets you specify when your computer should be awake or asleep. For instance, if you know that each day you're going to be away from it from 3 pm to 6 pm, you can program it to fall asleep during those hours. Additionally, you can program a laptop to go into sleep mode differently depending on if it is plugged in or running on battery power. ASUS M8 battery
Save Energy, Save Green
The company states that it can save you as much as $10 a month compared to if you leave the computer running all the time. That's a claim you can take with a grain of salt because, faithful Planet Green reader, we're sure you don't leave your computer running overnight! So your savings will be smaller than that, but you'll still be saving energy and carbon emissions. ASUS S1 battery

Dim Your Laptop Display To Save Power
No question battery life continues to be an extremely important part of laptops and mobile devices. The longer a battery lasts away from a power source, the more productive you can be. Better battery life might enable you to answer a few more critical e-mails, or allow your kids to finish that DVD on the long plane ride home. Asus G74SX battery

Battery life depends on many factors-the components used in the system, the power scheme settings, the kind of work being done and the physical size of the battery itself are just some examples. Lenovo G560 battery

There's also a number of ways to test battery life. From use case tests to industry benchmarks, battery test results can vary greatly. In the same way that two drivers will usually get different gas mileage driving the same car depending on how they drive, the same is true for testing methodology used by tech reviewers when evaluating battery performance. Testing methodology and user activity are two big reasons for this variance. LENOVO 43R9257

Looking at battery life in recent XPS 13 Ultrabook reviews shows this variation firsthand. Some reviews measure the battery life at around six and a half hours while others show it as little as three hours, thirteen minutes. In general usage, many of our XPS 13 customers are reporting six and a half hours or more. In our battery testing, that's what you should expect in general use. ASUS G50VM-X1 battery

Whether we're talking about the XPS 13 or any other Dell laptop, there are things you can do to preserve battery power. Adjusting the Windows Power Management settings is one way you can do it. Here's some specific tips: Samsung R780 battery

1. Select the Power Saver power scheme (vs. "Dell") by clicking on the battery icon in the system tray in the lower right corner. Power Saver is more aggressive than the "Dell" profile setting about reducing power draw. It's worth pointing out here that some tech reviewers turn OFF power management during battery testing which results in significantly shorter battery life. Both the Power Saver and "Dell" plans were developed by Dell in order to provide more flexibility. ASUS N53JF battery

2. Dim your display when possible. The XPS 13's bright 300-nit display is the single largest power draw on the system. If the environment allows for it, dim the display by tapping the FN+F4 key combination - this will help extend battery life.

3. In some circumstances, consider turning off wireless, by tapping the FN+F2 key combination (turn it back on the same way). Lenovo ThinkPad T410s battery

4. Also keep in mind some activities such as CPU-intensive tasks like video encoding, streaming video, and playing games will shorten the battery run time. A good example of this is Hot Hardware's review of the XPS 13. Note the disparity between the Battery Eater Pro test, 104 minutes - with all power management turned off- and the web browsing only test at 415 minutes, which takes advantage of our custom power management settings. Toshiba Satellite P505-S8980 battery

A little bonus tip: Pressing Win+X (Win = the Windows key) will bring up the Windows Mobility Center. This concise dashboard brings much of this together, giving you access to several of these settings at once. Using it, you can easily choose a power profile, adjust the screen brightness, enable or disable the wireless card and more.

The Facts about Laptop Batteries

A laptop battery is what makes your laptop run. Acer AS10D71 battery Without it, you won't be able to use your laptop unless it is plugged-in directly to a wall outlet. Think of the battery like the gasoline that fuels your car. These days, batteries are made of lithium ion and have an average power of around 4 hours. Acer AS10D73 Unlike gasoline though, your laptop battery would degrade over the long run. Why does this happen? There are two facts that affect this; one is that notebook batteries today last for an average of 300 recharges, and second these batteries have a lifespan of 3 years. If you go over these limits then your battery would not operate at its peak performance. It would be time then to get a replacement battery. Acer AS10D75

To make the most out of your notebook battery, here are some tips on how to extend its life. What I did to extend the life of my Dell D620 battery and my IBM Thinkpad T60 battery used on both of my laptops is that I made sure to use them efficiently. Acer BT.00603.111 First, since we are limited to an average of 300 charges, when you do a recharge make sure to do it when your battery is nearly empty so as to do a complete charge. If you charge your battery when it is still half full then you are wasting the extra power in it while cutting back on its lifetime. The same would go if you have a Latitude D620 battery, Inspiron 6000 battery, Dell 6000 battery, Dell 6400 battery or a KD476. Acer BT.00603.117

Next, try to minimize using your hardware. Examples of these are not to turn your LCD to its maximum brightness level and running only important programs when computing on battery. The more programs you open the more power your CPU would have to draw from the battery. Acer BT.00603.124 Also, try to cut back on some unimportant hardware usage. If you aren't using your WiFi try to turn it off. If you want to listen to music from a disk, then create a backup of the record and store in your hard drive. So the next time you play your music, it will be directly from the hard drive and not from a CD or DVR ROM which cuts battery lifespan real quick. Acer BT.00604.049

Even after trying to squeeze extra life on your notebook battery there will come a time when you really will have to replace it. If the original battery isn't available anymore then a replacement battery is a good option. These batteries are easy to find, just search the internet for any online store that caters replacement batteries. Acer BT.00605.062

Make Your Laptop Battery Last Longer: 3 Things to Know

Does your laptop battery give out a lot sooner than it used to? Are you lucky to get an hour or two of work done before you need to start searching for an AC outlet? Sounds like it's time to think about replacing the battery. Acer BT.00605.065
Get reader for sticker shock: laptop batteries are expensive. Prices vary from one model to another, but it's not uncommon for new power packs to sell for $100 or more. I've seen some as high as $150. When you consider that brand-new laptops now sell for as low as $300, that can be a tough pill to swallow. Acer BT.00606.008

Whether you're already in the market for a replacement battery or just concerned about the inevitable day when you will be, here are three things you should know:

1. Most laptop batteries start to fail in 1-2 years. This varies depending on your usage, of course, but the average laptop battery is good for around 400 recharges (a.k.a. cycles). After that, it starts to lose its capacity to hold a charge. Acer BT.00607.125

That's why the battery that once gave you, say, 3-4 hours' worth of runtime now peters out after just 1-2 hours. And after a few years, you might be lucky to get an even an hour.

2. You can extend the life of your current battery. If you use your laptop as your primary desktop PC, you may be wasting battery cycles by leaving it plugged in all the time. Acer BT.00607.126 The solution: pop the battery out until you actually need to go somewhere with your laptop. As long as the latter is plugged into an AC outlet, it doesn't actually need the battery.

Trust me on this: I've seen fairly new batteries that could barely last half an hour, even though the laptop rarely went anywhere. When in doubt, pop it out.

3. Investigate third-party alternatives. When you do end up needing a replacement battery, you don't necessarily have to buy one from the laptop manufacturer--paying top dollar in the process. Acer BT.00607.127

Instead, search the Web for the laptop make/model and "battery" to see if there are less-expensive third-party options. If your system is a popular model, there almost certainly will be.

Also, be sure to check out Dr. Battery's Advanced Pro Series. These replacement batteries--available for a huge range of laptop models--promise 800 recharge cycles (meaning they should last twice as long as your current battery) and come with a two-year warranty. Plus, they're priced fairly competitively at $88 and up. Acer BT.00607.130

By the way, you should always, always, always recycle old laptop batteries. Stores like Best Buy, Lowe's, and Staples have bins or kiosks where you can drop them off.

Okay, your turn: Have you shopped for a replacement laptop battery? If so, how much did you pay? Were you able to find any cheaper alternatives?

Pick Replacement Or Oem Laptop Battery For Laptops Acer LC.BTP00.123

You can save a lot money if you buy a replacement laptop battery immediately from the battery maker; however, not everyone knows where to discover the manufacturer. Furthermore, you can find different laptop battery shops on the internet, and they offer both OEM and replacement batteries at cheap prices.

This is correct of both physical stores and online websites that sell notebook computer batteries. However if you tend to be a value consumer, you will soon understand that universal batteries will provide you the exact same level of overall performance at a substantial cost savings. Acer 934t2078f battery Additionally, you might be able to boost your laptop's operating time by improving your laptop electric battery and choosing one with a higher milliamp rating in the generic equivalent. These higher total capacity generic batteries usually cost a lot less than the OEM's standard capacity battery power. Acer as10d5e

Common laptop batteries are generated at the same manufacturing plants that initially created the laptop battery for the computer producer; batteries are simply an out-sourced item for the computer maker. However these batteries may also be created at facilities whose requirements are not as great as the primary plant's and the only way to make sure that you have purchased a quality battery is to check the reputation of the supplier or the retailer, ensure that they provide a liberal warrantee and check the battery by charging it in your computer right after it is received. Acer as10d7e

The author carried out a case study and examined the cost to buy a replacement laptop battery for a Dell Inspiron laptop. He discovered that he could save a lot more than 50% on a laptop battery that offered a higher capacity and offered an expanded working time. The shopping for a replacement laptop battery article provides the details. You should check out replacement laptop batteries for much more getting tips and technical advice regarding personal computer batteries. Acer as10d41

There are many laptop batteries producers, and even more suppliers to purchase your laptop battery from. Nevertheless, your biggest concern in getting a laptop battery is going to be to pick the Acer Aspire 5520 Laptop Battery that works with your computer. Acer as10d51 For this you will need to realize the make and model number of your laptop; if you don't understand this offhand or don't possess the necessary paperwork, check the inside of your laptop computer's battery compartment while the personal computer is off and unplugged. There you should discover the model number, in conjunction with several other details. You may also find the part number of your mobile computer battery, located on the casing of the battery itself.

When getting a laptop battery, you will probably only have one or two choices that fit your personal computer. Select the battery with the longest life accessible for your laptop. There are several different types of laptop batteries; because the technologies of each are very different, a notebook computer should be designed especially for the type of laptop battery it uses. The majority of notebook computers are only designed to utilize one type of battery technology. Acer as10d61

Disruptive technologies: Lithium-ion batteries

Welcome to a Laptop Battery specialist of the IBM Laptop Battery First post by: www.askbattery.com

"To compete with advancing gasoline/diesel engines, EV traction batteries have to be much more than twice as energy dense as lithium-ion ever will be, at least three times cheaper, and last much longer before replacement," states a recent TrendTracker report. Dell P769K

So, does that mean that lithium is a dead end technology? What will it take to make lithium a truly disruptive technology?

Apples to apples, lithium-ion battery technologies simply don't compare to gasoline powered internal combustion engine vehicles. It's just not yet in the elements. That chemical reality has been acknowledged by many in the battery segment. Lenovo IdeaPad Y450 battery

For instance IBM Almaden Researchers working on future batteries note, "Since the efficiency of electric propulsion systems (battery-to-wheels) are about 90%, a 10-fold improvement of the current energy densities of Li-ion batteries, which are typically between 100 and 200 Wh/kg (cell level), would bring electric propulsion systems on-par with gasoline, at least as measured by gravimetric energy density. However, there is no expectation that current batteries such as Li-ion will ever come close to the target of 1700 Wh/kg. New chemistries are required to achieve this goal." HP HSTNN-IB25

No problem, right? Just tweak the solution in that beaker, son.

To resolve this problem, IBM researchers have been working on more futuristic battery technologies, such as lithium- air batteries. HP 628419-001 To wit IBM notes, "the requirements for large capacity automotive propulsion batteries are extensive, but quite well defined. They will serve as guidelines for the research to be carried out on Li-air systems. At present, automotive propulsion batteries are just beginning the transition from nickel metal hydride to Li-ion batteries such as IBM ThinkPad R60 Battery, after nearly 35 years of research and development on the latter. The transition to Li-air batteries (if successful) should be viewed in terms of a similar development cycle." Acer UM09E31

35 years? Are your fricken kidding me? Throw that beaker against the wall. Acer 31CR19/65-2

Of course, an unexpected breakthrough or some completely out-of-the-box thinking could turn these lithium-based chemistry studies on their heads. Unfortunately, that's a bet with low probability. Acer 31CR19/652

Nevertheless, that doesn't mean that lithium-ion batteries couldn't be a disruptive technology. Some kind of dynamic charging capability or a change in consumer expectations could rewrite the book on lithium-ion potential. Acer 31CR19/66-2

If for instance, 90 percent of your driving needs require less than 40 miles of range, why can't a plug-in with a minimum of 70 miles of electric power not be feasible? Acer AK.006BT.075

Because if you're gonna pay ,000 for a vehicle you expect far more functionality, right?

But, what if you were only paying ,000 for such a vehicle? Sure it might only be a two-seater. Additionally, such a vehicle might make even the science-fiction looking design of the Toyota Prius seem overly conventional. Acer AK.006BT.080

Regardless, would that really be so bad if such a vehicle were truly cost-effective? So cost-effective in fact that combined with the rental costs for an occasional weekend car for longer trips, your plug-in purchase was still far more cost-effective than any other vehicle?

Maybe. American consumers are a pretty fickle bunch. Acer AS10D battery

Inevitably, lithium-ion batteries are only going to be a disruptive technology if consumers revolutionize their thinking about personal transportation. And, if gas prices keep rising, such out-of-the-box thinking isn't really that hard to imagine.

Will it happen? Probably not, but it could, as could some completely unexpected technological breakthrough. Acer AS10D31

Of course, as hybrid cars have pushed automakers to embrace technologies like start/stop, perhaps lithium-ion can help automakers re-imagine plug-ins in a way never before imagined. Acer AS10D3E

For instance, battery-maker EnerDel's subdivision EnerFuel sees a future where something like the Chevy Volt could significantly reduce its battery size by replacing the gasoline engine with a small fuel cell as range extender with on-board gasoline to hydrogen reformer. Based on such a combination of technologies, EnerFuel envisions powertrain combinations that offer less overall range, such as just 200 miles, but at significantly reduced costs compared to the current Volt's powertrain architecture. Acer AS10D41

200 miles of range with instant fueling capabilities comparable to today's gasoline-powered technologies? Sure it's not perfect for cross country trips, but for everything else it more than works. Even for long distance trips it isn't pushing most consumers that far outside of their box most of the time. Acer AS10D51

Inevitably, lithium-ion batteries by themselves are probably not enough to become a disruptive technology; however, if lithium-ion technologies can provide the impetus to push automakers and consumers outside of their box of conventional thinking and expectations, lithium-ion could still become a disruptive technology.

Right Method to Use Netbook/Laptop Battery Acer AS10D61

Are you using laptop? That you use laptop batteries and how much they know? Long-term use to connect the power of the notebook, how good it save battery? This seems to look not very important issue, actually the life of this notebook has great impact. The following came to know the proper use of laptop batteries it! Acer AS10D71

First, battery program

Most laptops are equipped with automatic functions of reduced frequency, so that maximum benefit is to extend the books of the toshiba portege m400 battery. Many people who use the Celeron may have questions about books, our books do not have this feature, is not naturally less power out? Acer AS10D73 CPU consumption of electricity is only part of fact, the order should be like electricity: LCD> CPU (speed)> Graphics> Wireless LAN> CPU fan. In other words, in addition to CPU, we can start from the other side, the maximum reduction of electricity consumption. Acer AS10D75

In Windows XP Control Panel there is a power management option, the "power scheme", set the LCD screen about 10 minutes in the idle shut down the most reasonable and the hard disk will have to set more appropriate in more than 15 minutes. Instant boot disk does not need a certain power that frequently start and stop on the hard disk damage is considerable. Of course, you can also manually turn off the screen, most of the books are by fn + F3 function key to achieve. Acer BT.00603.111

Set LCD, hard drive shut down time, if you want to further save power, but also running on the system to adjust, it is not a Windows XP can do. Acer BT.00605.065 With Thinkpad, for example, most of the books have built-in battery management software, general books will provide eight screen brightness adjustment, although the state can get the brightest best visual effect, but it is very, very power-hungry, so , edit a document or some other common application to adjust the screen brightness to the lower six or seven best. At the same time, CPU can be set to the best battery performance, CPU fan running status set to "balance" is more reasonable. Acer BT.00603.117 battery

Second, the correct charging method

Many people use the laptop battery, that power began to charge less than 100%, but this will reduce the lithium battery power accelerating the total capacity last long, battery life much shorter time, but life on the greatly shortened . Therefore, the proposal battery will be limited to less than 10% charge from charging again, and be mindful not be set too low, such as the use to only about 3% charge left, which is not enough science. Insufficient power to set the alarm must be generally less than 10% of the alarm as well, less than 3% of the serious alarm means that the battery is insufficient to support the boot into the system the next time. Acer BT.00603.124 Many battery management software is less than 96% of the default start charging, it will damage the battery charge, so be sure to change this setting. In addition, the best off charging the battery so you can play the role of conservation.

Third, discharge necessary? Acer BT.00604.049

If the notebook's battery power for a long time greatly reduced, the depth of discharge can try to "save" it. This is a "dead horse a living horse doctors" approach, not a last resort, better not to do so. Discharge the simplest way is to constantly run the program, less than 3% of electricity to restart the books after running into the BIOS vacant until the automatic sony vgp-bps8 battery power-off date. Then the depth of charge, charging time to reach eight hours, but not more than 12 hours, so you can restore some power to lithium batteries. Acer BT.00605.062

extend the battery charging time is not a big problem

I often see the discussion of articles for books battery energy, say are some skills, but this is the books like to discuss every aspect of the battery, if the look and make you feel half the experts, then even if an end of the article!

Laptop Lenovo 0A36287 Battery camera camcorder battery

First to look at books from the perspective of saving the battery, as to energy conservation, it is necessary to first know how to avoid cell "aging"! Typically, the battery internal resistance with the use of time as the growth becomes larger and larger, there will be voltage drop mate, system voltage support is not sufficient, resulting in severe shortage of electricity. Over time this will be a vicious circle, seriously affect the battery life books. Lenovo 42T4845 This was lucky, sometimes your books battery failure will be a failure in a very short period of time, it is a headache! This failure is probably caused by batteries, this mostly occurred in the lithium battery, who are just like the books of the battery flashlight stabbed home as is a composition of one of the batteries, as long as one of a failure, then it will result in the overall series, voltage delay, regarding the scrap it! Therefore, to use electricity during charging, do not use industrial power, as voltage is too large, will affect the discharge curve! Lenovo 42T4847 Start charging, do not select the fast mode (BIOS setting), battery charging with constant current charging mode, the system load current, avoid the CPU, hard drive, LCD power struggle between the phenomenon. Discharge when the deceleration let CPU, hard disk stops and the screen transferred to the darkest (or closed off), do not run any programs until the laptop automatically shut down to achieve the objective of low current discharge. Also, if you can find in the market, "temperature protection device", then the best of! It can be achieved by adjusting the overall balance, very good battery backup protection devices

Now more and more people use the notebook as a notebook lithium batteries, one of the main parts of the problems also increases. So how good use of the notebook lithium batteries do? Grasp the main points:

1. To the appropriate charge and discharge current.

2. To minimize the discharge less than the charging or over-discharge. Lenovo 42T4235
Sina beautiful cheerleaders in the recruitment of free e-mail rose to 30 trillion
Sina China Internet Network Investment levy agents survey APPLE Laptop Battery DELL Laptop Battery

While the battery is a consumable, lithium-ion battery is no exception. Lenovo 42T4731 But no one wants to use up the battery fine spirit of God, to what age do not even rattle is finished, no one wants to start his own half dead battery does not pull the living, has been rubbing on it in 2023, makes good sad to realize how the thing about you is not?

Well, get down to business, following the battery began to speak. First explain, only lithium-ion battery HP Laptop Battery.

Appropriate charge and discharge current

General literature and the state standard on lithium-ion batteries on said lithium-ion battery charge current should be between 0.2C to 1C. Lenovo 42T4733 It is said that the charge current battery capacity, such as your battery is 4AH, then the 0.2C charge current is 0.2X4 = 0.8A, that is the charge current should be between 0.8 to 4A. In general, the charge current at the extent permitted by the smaller the better, rechargeable lithium-ion battery should be a constant current charging the start, in my IBM R31, this current is about 2.8A, equivalent to 0.7C, is charging its own circuit control can not set yourself. Although this indicator does not charge more than the standard requirement, but is actually relatively large, especially when the battery capacity decline for some time after the charge current may be more than 1C. Now the length of time charge notebook users have also become targets regardless of the manufacturers were forced to set such a high charge current. Lenovo 42T4737 battery

So first step is to reduce the charge current. I have a friend in the lab, all equipment readily available, on trial with him a bit. Power outlet on the first series resistance try a result, current is reduced, but became intermittent charge, this is not a good thing. Through trial and error, 4 Ohm is a more ideal value, this time around 0.8A charge current is very stable. This is only the current flowing through the machine power connector, Lenovo 42T4753 battery charge current is estimated to larger, should be slightly larger than 0.2C. Specific to a different machine, this value may be different. Also with the increase in battery voltage, charge current will be reduced, but the decrease rate is small, less than 0.05A. In this charge state, charging circuit seems to not work, the battery indicator light is not bright. Etc. Lenovo 42T4757 After the battery voltage up to 12.6V, charging circuits came into play and trickle charge the battery into the state, this time does not matter whether the series resistance has been, the charge current is controlled by the charging circuit, the last full charge after the charging circuit automatically end. The charging time is about 5.5 hours, if not resistance, charging time is 3.5 hours or so.

Lithium ion Lenovo 51J0499 batteries are very delicate, good charge control circuit is required. With this charging method, can reduce the charge current, battery life, while use of the books original charging circuit controls the charge is relatively simple to achieve them, just buy a power plug (that is, from the power supply plug into the notebook kind, the best to buy two, followed by the methods referred to still use one, be of good quality) and a resistor on it, pay attention to big head and little resistance, after all the above are about 2W of power Otherwise, it would be more heat resistance, preferably constant resistance of the wire myself one of the wire resistance and this resistance is independent of temperature. Lenovo ASM 42T4703 However, this disadvantage is also obvious that, while not charging work with books. In addition, when charging will have a strange phenomenon, I do not write omitted here, and you try to know, Fortunately, this phenomenon into the trickle charge after the state disappeared. To extend the charging time is not a big problem, anyway, before the night began to charge the next day wake up and fully charged, of course, if you are a night owl or a special short sleep time, that is another matter. Lenovo ASM 42T4752

Small current charging problem solved, and now discharge problem. In fact, this is difficult, after all, the book is used to work, the discharge current will vary with the working state, the method mentioned here only designed to restore battery capacity of the operation. Lenovo ASM 42T4756

Start the machine, set the power management will never go to sleep (standby) and hibernation (hibernate), others are set to the most power-saving mode, including CPU speed, turn off hard disks, turn off displays, while in TP management process Close some unused hardware, such as sound cards, etc., and then open the battery status display window, and allowed to run in the foreground! ! ! Close other programs, in particular, screen savers and other programs that run on time! ! Do not use the machine, do not close the lid, let the battery discharge end (not to discharge the minimum value set to 0, I set up 3%). Display and hard drive shut down, the discharge current is about 0.5A, this is my IBM R31 can be achieved on the minimum discharge current, battery LG Laptop Battery discharge to the minimum value of the machine will automatically shut down after. Lenovo ASM 42T4796 The discharge lasted for more than four hours, depending on your battery capacity may be different in different, this time is also used to sleep way to send the.

Well, the last to emphasize that the method is not dead, especially discharge, 10 times which can be done once, or else why should the battery? Lenovo FRU 42T4702 Charge all the best with a small current charge, of course, if the need to use batteries, power cord plugged directly into the notebook on it.

Using this method my battery is now fully up 14 times, the capacity has been maintained in 45 more, the battery design capacity is 43.2, and has come down, but after such a charge and discharge are restored. Lenovo FRU 42T4751

Beginning about two points, one appropriate charge and discharge, and second, not to discharge less than the charge, discharge less than the following to see how to solve the problem on the charge it:

To minimize the discharge less than the charge or over discharge Lenovo FRU 42T4755

In fact, over-discharge a good solution, not to terminate the discharge limits set too low on it, I have been using 3% LENOVO Laptop Battery.

Often use batteries may only be a short Shi Jian, such as battery remaining 70%, if the switching power supply, then the battery will Zidong charge, such a loop vanishes, although the battery's Shoumingbushi set to cycle the absolute number of death of, but always it will reduce the battery capacity, lithium-ion batteries have no memory effect reported, but in fact only a relatively low Bale memory effect. Lenovo FRU 42T4791 Unfortunately, IBM does not provide solutions to discharge less than the charging method, but provides the basis to solve this problem. This is what I found on the R31 may not be suitable for other machines, but the method should also not far off, do not forget after you've tried were posted for all to share.

R31 charging circuit based on the status of the power to decide whether to charge the Lenovo FRU 42T4793 battery. Power supply output voltage is 16V, within error of plus or minus 0.2V, if the voltage is lower than 15.5V, so not to charge the battery charging circuit, and books can also work, this is the IBM provided the basis for settlement. But the foundation is weak, because the voltage, if less than 15.2V, books will be converted to battery power, even if the power outlet in the books are useless. In other words, we can torment the space is 0.3V. Lenovo FRU 42T4795

If you can find a 15.5V, over current 3A switching power supply, then the problem is solved, otherwise please continue to look down IBM Laptop Battery SONY Laptop Battery.

Reduce the power supply output voltage 0.5V is not an easy thing, series resistance does not work, because the resistance of the voltage will change with the current size. I use silicon rectifier diodes, to allow more than through the current in the 2A, or hot tube. Silicon Rectifier diode forward voltage drop between 0.7 to 0.5V, just to meet the requirements. Now a plenty of such tubes in the electronics market, price less than 2 yuan. To a different book on the specific situation may be different, the best time to install a digital multimeter Cece hand. Pipe is being connected serially in the power output, and still harder to buy a power plug inserted himself in the notebook. Diode which is not reversed, the book does not work it wants, and then in turn connected on it.

In this way, the power output voltage drop is about 0.5V, if the drop too much, the book will switch to battery, if the drop too low, the book will charge the battery, the specific number to you in your own notebook tried to know.

Get The Most Information For Your Laptop Lithium Battery
Business > Advertising | By: largebattery2012 (05/28/12) Views: 3
I get a lot of questions about laptop batteries around the first of the new year. ASUS N50VN battery One of the biggest reasons is that many people get a laptop for a gift (or give themselves the laptop).I do computer repair and deal with laptops issues often Having been a laptop owner myself for more years than I care to remember,I also face the laptop battery problems any user might.Laptop batteries have come a long way since the first ones in the 90s.The latest type,lithium-ion or lithium battery,are a huge improvement in both power and endurance. ASUS U56E battery

But any laptop battery is subject to two very basic factors in determining the life cycle.The number of "charge cycles" (how many times the battery can be charged to 100% and depleted) and exposure to heat.The cycles eat into the ability of the battery to hold a charge and the heat causes the chemicals to lose their ability to recharge.The shelf life of any laptop battery is limited too.So if you are shopping for a replacement battery always check the date of manufacturer.If older than two years I would pass.Batteries do deteriorate over time just setting on the shelf regardless of use.It's a chemical thing and the ability to hold a full charge. Toshiba PA3921U-1BRS
When you do remove your battery you should store it in a cool and dry area.Some people go as far as to stick it in the refrigerator but that may not always be possible or convenient. DELL Alienware M14x battery I generally just put it in my laptop carrier so I don't forget it when I get ready to travel.I usually store it fully charged so it will have its maximum life when I use it.Some manufacturers recommend that if you are going to store it for a long time to do it at half charge.
The thing to realize about any battery is it does have a measurable lifespan and efforts to extend it will help but not stop the eventual demise. Sony VGP-BPS2C So the number one thing that you can do to extend the life of any of the newer lithium primary battery is always take it out if you are running on DC power to lessen the heat impact.Whenever buying any replacement battery,always check the manufacture date and try to find the newest one available.
There is also a lot of misinformation about batteries in general based on the older models and technology. Dell Vostro 1500 battery You do not need to totally drain the new lithium models.Its fine to use it until you get a warning of low power but don't purposely try to push it to empty since there is no reason to do so now. HP WD547AA And if you do push it to absolute no power you might also experience some lose of data,a very good reason not to go that route.Another common question is do I take out my battery while running on DC power?The answer is yes,this is due to the heat problem mentioned above.The amount of heat and duration can impact your battery's life so it's a good idea to remove it when plugged in to help limit the amount of heat exposed to when possible.
A majority of laptop users only use their laptops away from power in frequently so this could really be a big factor in making your battery last a long time.Asus X53E battery So what is a normal life expectancy of the newer batteries?You should check your manufacturer's specifications but the average is 300-500 cycles.So that number can mean different time periods for different users since it's very dependent of how often you use just battery power for operation. HP TouchSmart tm2-1000 battery From what I've seen from personal and customers use is to figure about 24-28 months is the average.Longer when you use it less away from DC power and if you remember to always remove when using DC power.

Extending the Life of Your Laptop Battery

Most modern laptops use a lithium ion battery. These batteries have a typical shelf life of two to three years with estimates of a 20% loss in capacity every year. Acer Aspire One 532h-2Db battery These numbers aren't very encouraging for a laptop owner, however there are several methods for extending a laptop's battery life that most of us are unaware of.

I was somewhat sceptical when researching the topic, expecting that extending the life cycle of a laptop battery would be a hassle (and indeed some of the suggestions feel that way at first), however there are some interesting findings and simple tips that one can follow to do just that. Asus A40J battery

Here is an interesting article about prolonging battery life. It uses somewhat technical jargon so I'll go ahead and interpret the findings into more common terms. HP HSTNN-LB2R

You should be using your battery regularly. If you're using your laptop on AC power, most sources recommend unplugging the battery and storing it in a cool place, such as your fridge (but not your freezer, cold is good but freezing is bad).

Several sources also recommend never keeping it fully charged if you're using your AC adapter. HP HSTNN-LB1Z The downside of a fully charged battery seems to be a higher temperature, and thus a quicker degradation. Expect a brief guide on how to ensure your adapter keeps your battery life at the % you want it at soon!

Once again however, it should be repeated; use your battery. HP HSTNN-DB0Q Several sources agree that you should use your battery until it's at 10-20% juice left then recharge it at least once every two or three weeks. Fully using the battery isn't recommended for Lithium Ion batteries; however some sources recommend emptying it out after a certain amount of partial charges (20-30 or more in some cases) and then fully re-charging it. HP HSTNN-XB1X Users such as myself, who use the laptop much like a desktop, always plugged into the AC adapter, seldom if ever actually use their batteries, which may explain why my old laptop's battery died after exactly two years.

These seem to be the most important methods in extending the life of your battery, however there exist some minor tricks you can use as well. HP HSTNN-XB1Y

Changing your power settings; you can adjust the profile you wish to use to maximize battery life for the sake of performance. Simply right click your battery icon and select properties then select one of the profiles available.

Lower your screen's brightness; pretty straightforward, less brightness means less energy being consumed. HP 582215-241 battery

Turn off virtual memory; virtual memory means your computer uses parts of your hard disk as temporary ram. HP TouchSmart tm2-1000 battery Communicating to your disk is energy intensive.

Be economical; this is pretty straightforward, if you're running your laptop on its battery, try to run fewer things, try to use less peripheral devices, be as conservative with what you use as possible.

HP HSTNN-DB0Q Considering many people don't get extended warranties and that replacement batteries can sometimes set you back 200$, these are tips we would all benefit from trying.
