■
When you charge the battery pack, charge it fully.
Charging an In-Use Battery Pack

Monitoring the Charge in a Battery Pack
Obtaining Accurate Charge Information
To increase the accuracy of the battery charge information that is
displayed by your notebook:
■
Allow a battery pack to discharge to about 10 percent of a full
charge through normal use before charging it.
■
When you charge a battery pack, charge it fully. The charge
in even a new battery pack may be reported inaccurately until
the battery pack has been fully charged at least once.
■
If a battery pack has been unused for one month or more,
calibrate the battery pack instead of simply charging it.
For information about battery calibration, refer to
“Calibrating a
Battery Pack,”
