Optimizing battery life

Optimizing battery life helps you get the most out of battery opera- tion, prolonging the charge/recharge cycle and improving recharging efficiency. You are advised to follow the suggestions set out below:

•Purchase an extra battery pack.

•Use AC power whenever possible, reserving your battery for on- the-go use.

•Eject a PC card if it is not being used, as it will continue to draw power.

•Store the battery pack in a cool, dry place. The recommended temperature is 10°C to 30°C. Higher temperatures cause the battery to self-discharge faster.

•Excessive recharging decreases the battery life.

•Look after your AC adapter and battery.
