Using the Battery Calibration Function
When charging/discharging the battery repeatedly for a
short time only, the battery usage time may be reduced by
the difference between the actual battery charge and the
remaining charge display.
In this case, the actual battery charge and the remaining
charge display will be the same by discharging the battery
completely using the Battery Calibration function, and
then recharging it again.
