Monitoring the Charge of a
Battery Pack
This section explains several ways you can determine the amount
of charge in your battery pack.
Obtaining Accurate Charge Information
To increase the accuracy of all battery charge displays:
■ Allow a battery pack to discharge to less than 5 percent of a
full charge through normal use before charging it.
■ When you charge a battery pack, charge it fully.
■ If a battery pack has been unused for one month or more,
calibrate the battery pack instead of simply charging it. For
calibration instructions, refer to “Calibrating a Battery Pack.”
