the Battery Calibration Function
When charging/discharging the battery
repeatedly for a short time only, the bat-
tery 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 com-
pletely using the Battery Calibration func-
tion, and then recharging it again.
