Calibrating a Battery Pack

Three steps are involved in calibrating the battery pack: fully
charging, fully discharging, and then fully recharging.
When to Calibrate
Even if a battery pack is heavily used, calibration should be
necessary only once a month. You do not have to calibrate a new
battery pack.
Calibration does not usually increase battery run time, but it can
increase the accuracy of battery charge displays, especially under
the following conditions:
When the battery pack has been unused for one month
or more.
When you notice a significant change in battery run time.
When battery charge displays seem inaccurate.
For more information about battery charge displays, refer to
the
this chapter.
