Taking Care of your Rechargeable Battery
To maintain the battery packís maximum capacity, occasionally you should let the computer totally deplete its battery power before recharging. If you have not been doing this, and your battery life has decreased you may need to do this discharge-charge cycle a number of times (3-5) to improve the performance.
End-users without specialist battery cycling equipment should follow the instructions below in order to cycle their battery.
Please note that all rechargeable batteries have a life-span of between 300-700 charge-discharge cycles (which normally equates to 1-3years). If this procedure gives no improvement in battery life your battery may have reached the end of its life.
