3.5.4 Calibrating the Lithium-Ion Battery
In order to keep the battery fuel gauge as accurate as possible, it is necessary to occasionally run the pack through a
recalibration cycle. To do this, place the battery in the left bay of the charger and press the button on the front label
(see Figure
3-9). This will initiate the recalibration sequence in the left bay only. The process can take up to nine
hours to complete and a recommended recalibration should be done once quarterly to keep the battery accurate.
