Calibrating the battery
Calibrating the battery ensures accurate battery level display. It is important to calibrate the
battery backpack and give it a full charge overnight or until the calibration timer expires the
first time you charge it. You do not need to charge the battery before you calibrate it.
Note: You do not have to calibrate the battery each time you charge it—only the
first time.
