Optimizing battery life
Optimizing battery life helps you get the most out of battery operation,
prolonging the charge/recharge cycle and improving recharging efficiency. You
are advised to follow the suggestions set out below:
•
Use AC power whenever possible, reserving battery for on-the-go use.
•
Store the battery pack in a cool, dry place. The recommended temperature
is 10° C (50° F) to 30° C (86° F). Higher temperatures cause the battery to
discharge faster.
•
Excessive recharging decreases the battery life.
•
Look after your AC adapter and battery.
