Monitoring the Charge of a Battery Pack

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 not been used for one month or more,
calibrate the battery pack instead of simply charging it. For
calibration instructions, refer to "Calibrating a Battery Pack"
later in this chapter.
