Calibrating a battery
To maximize battery performance, you should calibrate a battery under the following conditions:
ł
When battery charge displays seem inaccurate
ł
When you observe a significant change in battery run time
Even if a battery is heavily used, it should not need to be calibrated more than once a month. It is also
not necessary to calibrate a new battery.
To calibrate a battery and for additional information, select Start > Help and Support.
Storing a battery
CAUTION: To prevent damage to a battery, do not expose it to high temperatures for extended periods
of time.
If a computer will be unused and unplugged from external power for more than 2 weeks, remove the
battery and store it separately.
To prolong the charge of a stored battery, place it in a cool, dry place.
Calibrate a battery before using it if it has been stored for one month or more.
