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.
