Check for dust on the UPS case, wipe with a dry cloth if necessary;
Check the insulation condition of the input, output, and battery cables
for damage;
Ensure that the UPS is well protected from moisture;
Start-up UPS (see User’s manual);
Discharge UPS powered by the battery and other unimportant loads,
until the battery low voltage alarm sounds. During the discharging,
there shouldn’t be any other alarm. If any other alarm is triggered,
please contact local service center.
6.3 Battery maintenance
Batteries are the key component of the UPS. Its service life depends on the
temperature, as well as on the time of charging and discharging. High
temperatures and over discharge can shorten battery life.
1. Maintain ambient temperature in the range of 15 - 25°C.
2. In case of the UPS isn’t used for long time, it is recommended to fully charge
the batteries every 6 months.
3. Batteries should not be replaced individually.
4. Under normal working conditions, the battery life is about 2-5 years. If the
batteries were kept in a humid, dusty environment, or in low temperature
conditions, their service life will be reduced.
Algorithm of battery test are described below (battery performance may drop
dramatically as the end of its service life approaches, it is recommended to
check it at least once every 6 months):
Connect the UPS to the mains using the power cable, run the UPS and
charge the battery for more than 8 hours
Connect the load to the UPS and check its power. Unplug the input
cord. The UPS transfers to the battery mode, operation continues until
the UPS shuts down. After shutdown, you must fix the battery life. If
the battery life deviates from the values shown in the graphs from
