If you find that you are often using the computer with the battery at full charge while connected to the main power supply you may want to remove the battery. Keeping the battery fully charged while it’s at a high temperature, which is typical of conditions of a laptop that is always plugged into the main power supply, will dramatically shorten its lifespan. Discharging the battery on a regular basis also helps maintain a long battery life. Under optimal conditions laptop batteries will last 24 to 36 months. Under less than optimal conditions you may shorten the lifespan down to 12 to 18 months. To help keep your battery operating at peak conditions try to discharge it fully once a month.
