storage period, verify the battery level and recharge the battery when
necessary, so its charge level remains around 50 % of the total capacity.
This will ensure that you get the optimum performance out of the battery.
If the battery capacity remains low or outside the previously stated values,
it should be replaced. This could occur after 3 years depending on the
usage. If your current battery capacity is lower than 8000 mAh, replace the
battery.
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 Single Battery
Single-battery replacement should only be done by a qualified technician
with the appropriate tools on an electronic bench or similar environment.
To replace the single 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 LED Statuses on page 425.
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.
WARNING
Only use an EXFO battery. Batteries from other suppliers could
result in serious damage to the MaxTester or personal injuries. See
Contacting the Technical Support Group on page 426 for
