Calibrating the battery
Calibrating the battery ensures accurate battery level display. The first time you charge the
battery backpack, it is important to calibrate it and give it a full charge until the calibration
timer expires. 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.
