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 2-4 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 section 8.2 by more than 30%, it is necessary to replace
the battery

Perform an external inspection of the battery (remove dust and dirt if necessary)

Check the internal cable of all batteries for weakening or corrosion. Replace if
necessary

Ensure that the battery and battery terminals are firmly fastened
Notes:
1. Before performing battery operations, make sure the UPS is turned off and unplugged.
2. Remove rings, watches and other conductive materials before performing operations.
3. Use a tool with an insulated handle and do not put metal objects on batteries.
