Battery Pack Calibration
The internal battery pack contains a micro controller that monitors the battery pack characteristics
and maintains an internal “fuel gauge”. The internal fuel gauge may lose some accuracy after
many cycles of partial discharge and charge. Should this happen, the fuel gauge can be calibrated
with the following procedure:
z
To calibrate the battery pack fuel gauge:
1. Fully charge the battery pack.
2. Fully discharge the battery pack at a steady rate.
IMPORTANT:
The battery must be completely discharged! Operate the Diagnostic Tool until it shuts down by
itself due to a lack of power. Continue operating the tool when the “low battery” warning displays,
do not begin charging until after the tool has automatically shut down.
3. Fully charge the battery pack.
NOTE:
i
It is not recommended to perform the calibration procedure more than once within 30 days.
