Battery Calibration
In order to optimize the battery gas gauge accuracy, a battery calibration
procedure is accessible in the System Settings menu under
page 20. Going through this procedure may be necessary when first using
the MaxTester or after time depending on the number of charging cycles
the battery has undergone. It will optimize the gas gauge accuracy and not
affect the MaxTester's battery capacity.
Unit Temperature Handling
When the battery temperature reaches
55 °C, the unit temperature is
displayed in the bar at the top of the unit and a warning message will
appear. Tests stop automatically when the battery temperature
reaches 60 °C.
Replacing the Battery
Battery replacement should only be done by a qualified technician with the
appropriate tools on an electronic bench or similar environment.
To replace the battery:
1.
Remove all 4 screws of the battery back panel using a 1.5 mm Allen
key. Put aside the screws and the panel keeping the inside foam seal
clean. See
2.
Pull out the old battery using your fingers. Flipping the unit, battery-side
down, will ease removal. Do not use tools in order to prevent damage
to the battery envelope. Pull out the electrical connector. Put aside the
old battery.
