Steps to maximize the life of your battery

There are actions you can take to make your battery last longer during each charge cycle and live longer over many cycles. HP always recommends following the instructions for charging and storage that came with the battery or notebook. On this page we offer additional suggestions to help you get the most from your portable power supply.

Manage battery power more effectively in Windows

Make sure your battery gives the power you need, when you need it. Power Options in Windows XP allow you to control the power management features of your notebook PC.

Learn more about the Power Options in Windows by visiting Microsoft's support site:
? Microsoft: Power Management in Windows XP
Tips for conserving battery power on notebook PCs
You can manually change the power consumption of your notebook PC and conserve laptop battery power.

Reduce the brightness of the screen to the minimum readable level. Use the Fn and F7 or F8 keys to adjust the brightness.

Remove peripherals when not in use. External hard drives, CD-ROMs, Zip drives, PC cards, and other peripheral devices can draw power from your EVO N400C battery even when they are not in active use. Disconnect them when you have finished using them. Reduce the speed of your processor. The faster your computer works, the more quickly it uses up the supply of power. By cutting down on processor speed, you can extend the charge of your battery. Methods to reduce processor speed vary from model to model, and your manual should provide instructions for doing so.

Turn off the Wireless On-Off button when it is not in use. If your notebook has one, press the Wireless On-Off button so that the light turns off.

Battery care practices

Battery cells suffer gradual, irreversible capacity loss over time. Such aging occurs more rapidly as temperature and discharge loads increase. Here are some suggested ways to minimize the capacity loss for your F4809A battery.

Store Li-Ion batteries between 20įC and 25įC (68įF and 77įF) with 30% to 50% charge.

Do not leave batteries exposed to high temperatures for extended periods. Prolonged exposure to heat (for example, inside a hot car) will accelerate the deterioration of Li-Ion cells.

Remove the battery if the notebook will be stored (turned off and not plugged into AC power) for more than 2 weeks.
Remove the battery if the notebook will be plugged into AC power continuously (via a wall adapter or docking station) for more than 2 weeks.

Note: Recommendations for battery use and storage are covered in the HP ZE4400 battery User Guides for each model.

Calibrate the notebook PC battery

Short discharges and recharges do not fully synchronize the VGP-BPS2C battery's fuel gauge with the battery's state-of-charge. This can result in the amount of power available in one cycle being less than expected or the battery meter being inaccurate.

Under normal usage, Presario 2100 batteries should be calibrated a minimum of once every 3 months. Your battery can be calibrated by following these steps:
Step 1 - Disable the Windows Power Management
In Windows, right-click the Desktop and select Properties in the menu list.
Click the Screen Saver tab and then click the Power button.
Under Power schemes, select Always On in the drop down menu.
Under Settings for Always On power scheme, select Never in each of the drop down menus.
Click OK on the Power Options Properties window and then click OK on the Display Properties window.

Step 2 - Fully charge the battery
Connect the AC adapter to the notebook.
Charge the Ibook G3 battery until the Windows battery meter is at 100%.

Step 3 - Fully discharge the battery
Remove the AC adapter.
Keep the notebook on until the battery has completely drained and the notebook automatically turns off.
Connect the AC adapter to the notebook.
Keep the AC adapter connected to the notebook until the M8416 battery has completely charged.

Step 4 - Enable the Windows Power Management
In Windows, right-click the Desktop and select Properties in the menu list.
Click the Screen Saver tab and then click the Power button.
Under Power schemes, select Portable/Laptop in the drop down menu.
Click OK on the Power Options Properties window and then click OK on the Display Properties window.

The truth about notebook battery

The truth about notebook battery

Itís one of the most important and least understood parts of your notebookóand it provokes so many unanswered questions. Why do laptop batteries gradually lose their ability to hold a charge? Why does it takes longer for a charging notebook to go from 80 to 100 percent charge than it does to go from zero to 80 percent? Whatís the difference between a three-cell and a six-cell battery? Rather than shrug our shoulders for another day, we demanded answers from two experts, Matt Kohut, worldwide competitive analyst at Lenovo; and John Wozniak, Ph.D. distinguished technologist at HP.

LAPTOP: At what point during Presario 2100 battery life cycle does a typical notebook battery last longest?

Kohut: The industry average is about 30 percent degradation per year. Youíll probably start to notice after about six months.

John Wozniak: Batteries tend to fade pretty quickly over the first 10 or 20 cycles, and then capacity levels off.

How long does a typical notebook battery last?

Kohut: Roughly, 350 charge cycles. A cycle is cumulative use that reaches 70 percent degradation, or seven times when 90 percent of the battery capacity was used.

What causes a battery to lose capacity over time?

Wozniak: Think of a Presario 2500 battery as having pores, where the electrons flow back and forth between the cathode and the anode. When those pores get clogged, you canít move the electrons as efficiently anymore. Then the lithium gets bound up on one side or the other, and it no longer contributes to the movement of electrons. It gets backed up.

Do you need to build up a battery memory, or condition it, to get the best performance?

Kohut: This was true in the lithium-metal hydride days, however, with a standard lithium-ion battery, you just need to make sure you charge it fully. Most batteries ship from the manufacturers with an 80 percent charge.

Conditioning, meaning draining the battery to zero and then charging HP ZE4400 battery fully while Windows monitors it, resets the curve. It doesnít prolong the batteryís life, but it improves accuracy [of the battery monitor]. Over time, the accuracy drifts in the Windows program that measures battery life. That is why it can say that you suddenly went from 80 to 20 percent in five minutes.

How much can you trust the charge status that Windows gives you?

Kohut: If the battery reports full, Windows says it is full. Windows periodically checks the battery, but it is more of a thumbs-up/thumbs-down than a real assessment. Windows is crude; trust it if itís full, trust it if itís empty. But know that it doesnít have the communication to know that the Pavilion DV2000 battery degrades over time. We recommend the Lenovo Power Manager, because it has a lot more smarts. It knows the status of each individual cell, whether itís balanced, imbalanced, charging, not charging, etc.

John Wozniak: If the BIOS is written correctly, Windows is really accurate; within 1 to 2 percent. The problem is how often it updates.

When charging a notebook, why does the last 5 to 10 Percent take longer than the first 85 to 90 percent?

Kohut: If the EVO N400C battery is low, we will charge it at a faster rate. But when the battery fills up, we back off, because itís the last bit of charging that causes the issues to form. Other vendors that do rapid charge still back off around the last 10 percent. Dell, for example, does fast charge, pedal to the metal, from zero to 80 percent. Then backs off and coasts into the finish line. Lenovo starts fast, but backs off more and more through the entire charge. This allows for a more even rate of charge. It takes longer overall, but it helps the batteryís longevity.

Some notebooks wonít start charging unless the battery is below a certain level, SAY, 95 percent. Why is that?

Kohut: Charging it to 100 percent every time adds cycles that cause the inspiron 1525 battery to wear out faster. In the typical office situation, youíre plugged in 100 percent all day. Then you take it home, and plug it in again, after losing maybe only 2 percent. If you charge to 100 percent again, you start adding cycles that wear out the battery because youíre initiating a full charge cycle. The thought behind our process is that unless the battery gets below a certain percentage, donít put it through the stress of charging.

How important is the number of cells in determining battery capacity?

Kohut: The three-, six, nine-celled battery is shorthand for explaining how much laptop battery life a machine has, but watt-hours hours determine capacity. The average consumer has no clue that a nine-cell battery has around 84-watt-hours of power, they just know itís a nine-cell. One of Lenovoís competitorís has two six-cell batteriesóa 53-watt-hour and a 47-watt-hour. The second doesnít deliver the same capacity. To really understand how much power a battery will hold, you need to look at the watt-hours.

Some vendors are advertising two- or three-cell batteries that claim a longer life than six-cell models. Is that possible?

Kohut: There is a fine line. Ibook G3 Battery VGP-BPS2C capacity has gone up in the past few years by making the cells more energy-dense. There used to be 2 amp hour (Ah) cells, but now cells go up to 2.9 amps. If you can control the higher concentration of energy in the smaller space, itís not a problem. But sometimes this results in violent reactions such as overheating and over-charging. [If a vendor claims its battery lasts a long time with fewer cells,] you want to ask how many watt-hours the pack holds, and about the kind of cells (2.6, 2.9 Ah, etc.).

Should consumers trust third-party batteries?

Kohut: Weíll warranty our own batteries, but if you put a third-party battery in, you void the warranty. Thatís because there are good Powerbook G4 battery manufacturers and there are bad ones. Some of the good ones are Panasonic, Sanyo, and Sony. A less reputable company will buy whatever is cheapest, and just drop it in there. The reason a lot of the battery incidents occur in this industry is because of quality control.

We always say that you are taking [the life of your notebook] into your own hands when you buy a third-party battery pack. Yes, you are saving some money up-front but you donít have the backing of the company behind it.

Maintain batteries for daily use and maintenance

Notebook computer battery is the consumables, the battery once opened, will begin the process of aging. With the aging of the chemical characteristics of cells vary. Aging with the use of normal methods. If the frequent charge-discharge of BATCL50L batteries, it will accelerate the aging batteries. Battery life over a period of time, power will gradually shorten the time until the can not be used. Therefore shorten the battery life is a normal situation. Most of you who normally use an external power supply, like not using the travelmate 290 battery, but a matter of fact, the aging process of the battery over time has been less of the battery can only delay the process, but can not make it stop.

The impact of factors such as battery life:
Battery charge / release number of the use of the environment temperature (30 ℃ suggested that the use of temperatures below computer) battery storage temperature Shock suffered by the size of the BATCL50L4 battery

Battery using must follow the below "principles"

1. AC Adapter (external power adapter) mode, use the battery if it has not gone through charge / discharge process, the life will be longer than the normal battery.

2. A smaller number of charge and discharge a certain extent, can extend aspire one battery life.

3. In the indoor temperature above 35 ℃, the battery wear and tear than the normal speed when the temperature much faster.

4. Throw, hit, etc. batteries will also accelerate Travelmate 290 battery depletion.

Application of the following battery will significantly shorten the working hours.

  1. The use of CD-ROM drive, such as DVD, CDROM and CDRW drives.
  2. The use of wireless communications equipment, an external PC card or USB device.
  3. The use of high-brightness display settings laptop battery, 3D screen savers or other programs, such as 3D games.
  4. In the highest performance mode of operation of the computer, power management program that is set to "always open" or "Max Battery mode."
  5. The activities of procedures, including procedures for running in the background.
  6. LCD brightness (LCD more light, the greater the power consumption).

Dell Laptop battery maintenance guide

Battery is the consumables, with a limited life expectancy, most manufacturers warranty for the notebook battery time ranging from three months to a year, Dell is to follow industry standards to provide a limited warranty for one year. For batteries, use the correct and proper storage, can significantly extend the Dell E1705 battery life of notebook computers.

First, the battery useing must follow some attention points.

1. When you use laptop with external power, you dont need to take out the battery.

  1. There is a chip to prevent over-charging in the mainboard. When the rechargeable battery power to 100% state of charge, the charge control chips (FET) will stop charging the battery. We do not have to worry about damage to the battery.
  2. Connect the 851UY 75UYF 1K500 battery to avoid loss of BIOS information.
  3. To prevent a sudden loss of power break.

2. To prevent exposure to prevent damp to prevent the erosion of liquid chemicals, batteries to avoid contact with metal objects, such as exposure to short-circuit occurrence.

3. Long-term do not use notebooks, how to store the laptop battery?

We will have a period of time not to use the notebook, the 851uy 75uyf 1k500 battery is fully charged to preserve, or to be released after save electricity?

Put long-term preservation of photoelectric batteries will lose their activity and even lead to the control circuit protection self-locking and can not re-use, full of power will bring about long-term preservation of the safety problems, the best method is to save electricity use to 40 or so and then stored in cool dry place, about 20 degrees Celsius is the ideal storage temperature. Of course, the best month to come up with to use a battery, the battery can ensure a good state of preservation, but also does not allow the loss of electricity damage to the battery completely.

How can I exam the Dell battery power? (For example in cell D610 battery)

Remove the battery, press the Macbook Pro battery power signs, we can see the situation of the five battery status lights. For two bright, representing 40% of the electricity. Electricity on behalf of the entire light is sufficient, if the 135-light, that damage the battery.

Second, how to extend as much as possible the work of laptop battery time?

  1. To reduce the screen brightness. How to adjust the brightness of the use of laptop batteries, boot by F2, into the BIOS to adjust the Brightness of Video. Or fn + down / up key combination to adjust the brightness quickly.
  2. Open the CPU speedstep feature, you can greatly extend the working hours of latitude x300 battery; Cpu's speedstep feature is enabled by default BIOS of. When using batteries, cpu will automatically down-use, in order to achieve energy-saving purpose. If not enabled, please start by F2, into the BIOS found in Performance, for the Speedstep Enable setting Enabled. (An earlier version of BIOS is the Alt + P to the sixth page, modify intel speedstep)
  3. make the best use of standby, sleep and other functions. When a longer period of time without a computer, allowing notebook standby or hibernation, both to save power and extend the life of the computer. (Tips: Please confirm the successful installation of graphics drivers, power management options can be set up.)
    WINDOWS in the process of power management settings, we generally can be set to "portable / laptop" (Portable / Laptop).
    At the same time suggest that you will use the powerbook G4 battery when the wait time to close the monitor is set to 5 minutes, so when we do not operate within a certain period of time the notebook, it will direct the state of black screen, so other than the screen saver to run more power.
  4. when using the battery as much as possible the closure of wireless, Bluetooth and infrared ports. At the same time to remove without the use of peripherals and to avoid the opening of a large 3D program, games and so on, in order to reduce unnecessary battery consumption.

Of course, on the controversy over the use of batteries, there are divergent views have any objection if we can http://bbs.dell.com.cn forum to ask questions, let us discuss how to maintain the battery.

Thinkpad 60 Series "frozen to death" (freeze) solution

By laptopsbattery - June 15th, 2009, 20:25, Category: General

Thinkpad 60 Series "frozen to death" (freeze) solution

Freezing to death is not clear as characteristics, mainly performance freeze, screen images can be seen, but can not operate as if time stopped, the Thinkpad T40 battery hard disk light does not flash, other lights lit normal, press the power button can only be forced to restart, restart without self-test. Take it to service station hardware, the operation shows all normal. This may not be Thinkpad X60 battery probelm, but Core 2 series processor problems. Thinkpad currently address these issues, and Intel have been carried out corresponding measures. Of course, this does not solve the fundamental problem of freezing to death, but has been greatly eased, and so will be to minimize the probability of occurrence.

Solve this problem in five steps:

Step one: Upgrade BIOS, Lenovo officials online have the latest BIOS version 2.19
Download link, http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-63024,
Of course, also mentioned the need to upgrade, and strongly recommended, which the BIOS upgrade in the history of Thinkpad X60S battery is also relatively rare. BIOS upgrade would not say, and in accordance with the step by step readme on the list, no less dangerous, but should pay attention to the battery and AC must be used to prevent power outages, upgrade other programs to close, remember to turn off antivirus software and firewall.

The second step, Intel dual-core patch upgrade, download links
http://support.microsoft.com/kb/896256/zh-cn, even after the patch upgrade some manual operation, see the details, http://publish.it168.com/2007/0425/20070425015807. shtml.

The third step is to upgrade Intel micro-code of your thinkpad T60 battery, download link
http://www.microsoft.com/downloa ... 0 & displaylang = zh-cn, the most simple, you can click Run.

The fourth step, upgrading your Thinkpad T61 battery graphics card driver, download links
http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-62841

The fifth step, upgrade the Thinkpad battery power management process, the download link
http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-4GXPEG
http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-61583

That's all.

Laptop battery using mistakes

Laptop battery using mistakes

Lives Longer In BIOS? - This is one of the few troubleshooting diagnostic tests you can do at home to find out if your A1057 A1057 battery life problem is due to a hardware flaw or to the way the laptop is being operated. Enter the BIOS setup immediately after turning on the notebook on with a fully charged battery, usually by hitting the DEL key, the F1 or F2 key immediately after you power on. Some laptops display a text message telling you what key you need to hit to enter the BIOS setup, on others the message is suppressed by a BIOS setting, but you can always go online and Google the right key combination if it's not in your manual. Once you bring up any BIOS screen, measure the time it takes the laptop battery to run down. If it doesn't outlast the battery life under regular usage by a good margin, the short battery life is probably due to a faulty battery or a hardware failure that causes the laptop to continually suck power when it shouldn't.

AC Adapter Noisy? For starters, this is one of those problems that tends to bother more women than men, because men lose their high frequency hearing at a much earlier age than women. Battery chargers typically include a transformer and some power IC's, at least a bridge rectifier. There's a lot of potential for humming and whistling with transformers, but they can go on operating that way for years without failing. If the battery charger gets very hot, then it's time to check the manufacturer specs for temperature and see if it needs replacement, and check the U4873 D5318 battery temperature as well. In all cases, the acoustic behavior of your AC power adapter and charger may naturally vary with the quality of the power from the utility, and the feed voltage if you are traveling. Anytime you can avoid running a computer on poorly regulated or intermittent utility power you should do so, but at least with a laptop you're better off than with a desktop.

OS Battery Management Active? Older notebooks were equipped with hardware only battery management schemes that controlled both charging and battery operation. All new laptops ship with ACPI (Advanced Configuration Power Interface) which is a marriage between BIOS routines that monitor board level charging and device activity, and the operating system. The operating system power management comes equipped with a number of default profiles that instruct the laptop if and how to nurse the U4873 D5318 battery. There's usually a power user profile that just runs full out with no consideration of battery life, a number of special purpose profiles, such as running a DVD movie for a sole task, and a miserly setting that cuts performance to a minimum and puts devices like the hard drive to sleep when not in frequent use.

You can micro-manage these profiles to suit your needs, and you can always go into the settings and override them or change the profile at any time. The most useful trick to remember for running on G5266 HD438 KD186 battery is how to brighten or dim the LCD screen using the the function screen. Screen brightness is a serious power drain (you're essentially powering a small fluorescent lightbulb) and in most indoor usages, strategic choice of where you sit can add time to your battery life. When troubleshooting battery life issues, you may want to run a power management profile that doesn't come up to your expectations for performance for a few battery cycles just to help diagnose the problem.

DC Voltage Good? Check the voltage at the output of your AC adapter with a DC voltmeter, right on the barrel connector that gets plugged into the laptop. The rule of thumb for acceptable readings on power adapter output is usually a 5% variation either way of the faceplate voltage, and in terms of charging a G5266 HD438 KD186 battery, a high reading is better than a low reading. If you've purchased a lightweight battery charger for travel, don't assume that it's putting out the correct voltage just because there's a connector that fit your notebook. Check your owners manual or the label on the original battery charger that came with the notebook.

LED For Charging Blink? While there's no universal standard, a blinking LED on the battery charge indicator is probably not good news. It often indicates a battery that has been over-discharged, the voltage is so low that it's confusing the charging circuitry into thinking the battery has a dead cell and would just overheat if a charge is pushed into it. The newer the laptop, the smarter the charging logic, and it won't want to try putting a charge into a battery that may damage either the battery or the notebook itself. In some cases, you'll be able to recharge an over depleted inspiron B130 battery if you wait until the notebook is shut down, install the battery, and then plug in the the battery charger, but I'd keep a close eye (and occasional finger) on it for overheating. There are also fuel gauges built into some newer batteries that simply disable the battery when it reaches it's planned cycle life.

Does Battery Get Hot? Recently there have been a spate of high profile stories in the media about laptop batteries catching fire. This wasn't caused by normal heating due to charging. The problem was in the manufacturing process of the individual cells, where apparently some contamination led to internal short circuits that could cause the battery to overheat even if it wasn't in use. Powerbook G4 batteries normally heat up a little on charging, and they heat up even more when discharging under heavy demand. Battery packs usually include a temperature cut-off circuit, that will halt battery charging or discharging if it really overheats. In some cases, the battery will not be usable afterwards because the cut-off acts like a circuit breaker that can't be easily reset.

It certainly doesn't do your laptop battery any good to get very hot, even if it's within the toleration of the protective circuitry, so if it's overheating on discharge, consider running on AC power instead. Just remember you have to shut down before removing the Acer 3000 battery unless it's specified as being hot-swapable:-) You can also try decreasing the performance settings to lower the power drain. If the battery is overheating on charging, you can try charging when the laptop is turned off since the laptop is generating heat as well. Also, pay attention to the ambient air temperature. All notebook computers depend on the ambient air for cooling, so unless you are running the computer on a special cooling pad, think twice about using it on those 110 degree days!

Latch Locks Tight? It's impossible to see what's going on with the connector contact inside the battery compartment once the battery is installed, so the only indicator you have to proper installation (aside from normal operation) is the condition of the latch. If the latching mechanism doesn't show a positive close by clicking back to the relaxed position, try reinstalling the battery. Some laptops have a manual battery lock that is operating separately from the latches, and which will not lock unless the battery is installed properly. If the latches refuse to click closed on their own, remove the battery again, visually inspect for any bulging or distortions in the package, and check the connector for damage.

Notebook Battery daily maintenance FAQ

Note that these steps correspond with decision points on the flowchart and are reached directly by clicking on the diamond symbols. The text below cannot be read sequentially.

Needs AC Adapter to boot? The first step in troubleshooting your inspiron e1705 battery is determining whether it can hold enough charge to boot the notebook. Will the laptop power up and run on the battery, or does the AC adapter which doubles as the laptop battery charger need to be plugged in? Modern notebooks usually have a whole array of status LEDs that will tell you if the laptop senses good power coming from the battery charger and whether or not the battery is charging. Unfortunately, there's no universal standard for these LEDs, their colors or their actions. Note also that we're using the term "boot" rather loosely here. If the laptop powers up on battery, you can hear the fans and the drives, your troubleshooting problem lies elsewhere.

Life Of Battery Too Short? This is the main problem laptop owners complain about, and often for good cause. Older laptops using Ni-Cad and early Ni-MH inspiron 6400 batteries often ran for 2.5 to 3.5 hours when brand new, but within a month or so, would barely keep the notebook powered up for an hour. Newer laptops using Ni-MH and Li-ION batteries are much better, often holding onto a three hour life through hundreds of charge and discharge cycles. The first line of defense against complaints about battery life by the manufacturers is always, "Did you charge and operate the battery according to the manual?" Unfortunately, different laptop manufacturers seem to disagree over how to best treat GD761 batteries of the same technology, and I wouldn't be surprised if the differences extend to different models from the same manufacturer.

If the laptop's Dell D610 battery life has been slowly degrading over time, it's probably operating more or less in accordance with plan, but if you find the operating life shortened by more than 15% or 20% within the first few months, there's probably something wrong. Batteries of all technologies can be "trained" to perform poorly through non-ideal usage patterns, but the Li-ION battery technology is pretty resistant, and as long as you run them all the way down once a month or so, you can probably prevent any serious charging memory issues.

Is Battery New? Purchasers of brand-new laptops are often surprised to find the battery is dead, or runs down very quickly. Even if the a1175 battery was fully charged when the laptop was boxed for shipment, that box may have been sitting in a warehouse for six months or a year before you purchased it in a store, more than enough time for a notebook battery to self discharge to an appreciable degree, even if it's not being drawn upon. If the battery isn't new, and you just received the laptop as a hand-me-down or purchased it second hand, there's no reason to expect that a short Ibook G4 battery life is due to anything other than an aged battery. You can try to recondition the battery (see the laptop manufacturer website for for software that may be available), but odds are the battery simply can't hold a charge the way it did when it was new.

User Condition Powerbook G4 Battery? Some manufacturers may condition the battery before installation in the laptop, others expect you to read the owners manual instructions and do it yourself in the first few days you own the laptop. The most general procedure is to charge the battery fully before use (leaving it on the AC battery charger overnight is best), and then to run exclusively on battery until the battery is discharged. Some brands suggest you run until the operating system warns of low battery life remaining, which could be anywhere from 10% to 3% remaining on standard settings. Others recommend that you run the laptop until it shuts itself down. This doesn't mean that you have to sit there working for three or four hours, you can run the Macbook Pro battery down over multiple sessions over multiple days. The important thing is not to plug the AC power adapter back in and start recharging the battery until it is completely run down. The condition process generally requires you to go through this cycle three times in a row.

Runs Always With aspire 3000 Battery? If the owners manual for your notebook suggests removing the battery when plugged in for prolonged periods, doing so may greatly prolong the battery life in terms of both charge cycles and years. Personally, I tend to be lazy and just leave the battery in all the time, despite the fact I almost always work plugged in. The battery life on the first couple Toshiba's I owned dropped down to a half hour or so of running time within a few months my buying them, so it may have been my fault. Li-ION Aspire 3000 batteries are much more friendly to poor power management habits, but you should run them down to empty once a month to keep them from developing a memory.

Battery conditioning means training the individual LCBTP03003 battery cells into a pattern of giving as much power as they can and accepting the largest charge that they can. It would take an advanced chemistry text and a person much smarter than I to describe the underlying reasons for battery memory, and the techniques for best charging and storing batteries sometimes contradict one another. Once a laptop battery pack is conditioned, you may still need to run it all the way down once a month for best performance, especially if you normally work with the laptop plugged in. It's important to read the owners manual section on battery life, because different models ship with different battery technologies, and the best practices to extend the battery life may not be the same.
