1. Change the power settings on your computer to conserve the battery by selecting a power-saving setting.

3. Keep your computer and battery away from extreme temperatures. Extreme temperatures make the battery lose charge, and may also stop it from working altogether.

4. Allow your battery to work by unplugging the computer from a power source periodically. If you keep the computer plugged in all of the time, the battery does not have a chance to discharge, and this shortens its life.
