To maintain and preserve battery life
To preserve the life of your battery, be sure to charge the battery regularly. In cases
of long-term storage, the battery must be charged at 20–50% to prevent capacity loss
by
self-discharge and to avoid deterioration of battery performance.
•
Do not leave batteries unused for long periods of time. If you have more than
one, rotate them.
•
If you use ac power, make a point of using the battery once a week to keep it
fresh.
•
Unplug your ac adapter when the computer is not in use.
