Tips for Maximizing Your Battery Life
Your ThinkPad battery is a "Consumable" product that decreases in performance over time. However, there are several things that you can do to improve the performance and life of your battery.
Here are some tips to help maximize your battery life:
1. If your battery is left out of the system for a long period of time without charging, or if the system is not plugged in for several months, it will take longer to charge.
2. Make sure that you are using the correct AC adapter for your ThinkPad model. Using the incorrect adapter will prevent the battery from charging fully, and will cause the battery meter to display incorrect battery information.
3. Recondition your battery by letting your battery run to less than 3% at least once a month. Reconditioning the battery can restore some of your battery capacity.
4. When the computer uses a large amount of electricity from the battery (for example, for intensive calculations or high-end graphics applications), the temperature of the battery and the computer may rise. In this case, the battery might automatically stop charging to so that the battery operates at a level that ensures comfortable usage and normal battery life. If the battery has stopped charging, it might not start charging immediately when you plug in the AC adapter or it may take more time to completely charge. When the battery is restored to its normal temperature, the battery will start to recharge.
5. Do not place your battery or your ThinkPad in a high temperature environment, such as a car on a hot day.
6. Battery performance will be temporarily degraded if the battery is used in a cold environment.
7. When you store your battery outside of your ThinkPad Computer, store it with a charge of less than 50% to reduce the battery wear.

Reconditioning The Battery
Reconditioning your battery can increase the full charge capacity of your battery. It is recommended that you let the battery run to less than 3% at least once a month.
Occasionally, it may be necessary to "deep cycle" your battery one to three times to give it optimum performance. This will require you to let your battery run completely down, and then to recharge it fully. It is recommended that you charge your ThinkPad overnight for a full charge from a deep recharge condition without leaving your ThinkPad powered on. A brand new battery should be fully charged overnight before its first use.
To do this, perform the following steps:
1. Make sure you have saved all of your data, and close all programs.
2. Disable Power Management timer settings so that your ThinkPad keeps working during reconditioning the battery. You need Administrator or Power User privileges on Windows 2000 or later.
a. Record your current power management settings by clicking these buttons.
After reconditioning your battery, you might want to restore these settings to your previous settings.
b. Set Battery MaxiMiser Disable Shut-off Timers scheme, by clicking this button.
3. Disable Hibernation and Standby before a battery is fully discharged, by clicking this button.
to set default low battery alarm settings.
Note that you need Administrator or Power User privileges on Windows 2000 or later.
4. Determine your battery chemistry. It will either be Li-Ion or NiMH.
5. Let the battery totally discharge, then let the battery charge.
Perform the following steps if your battery is Li-Ion:
a. Unplug the AC adapter and let the battery totally discharge. The computer automatically goes to standby mode when the battery is fully discharged.
b. With the proper AC adapter, let charge the battery until Battery LED is solid green.
Perform the following steps if your battery is NiMH:
a. Plug in the proper AC adapter .
b. Click Start Refresh button in the Battery Health dialog to start reconditioning your battery. Battery starts discharging. When battery is fully discharged, it will start charging automatically.
c. When the battery LED is solid green, the charge is completed
