10.2 Batteries
The RT 1-3kVA series UPS uses sealed lead-acid batteries. Though the typical
battery life cycle is 3~5 years, the battery life depends on the temperature, the
usage, and the charging/ discharging frequency. High temperature environments
and high charging/ discharging frequency will quickly shorten the battery life. The
UPS does not require maintenance by the user; however, the batteries should
be checked periodically. Please follow the suggestions below to ensure a normal
battery lifetime.

Keep the usage temperature at 20°C ~25°C.

Idle batteries must be fully recharged every three months if the UPS needs to be
stored for an extended period of time. Please fully charge the batteries (internal
and external) until the Battery Level Bar Graph
shown on the UPS’s LCD is
fully on.
NOTE:
If the UPS’s internal batteries need to be replaced, please
contact qualified service personnel. During battery replacement, the
loads attached to the UPS will not be protected if input power fails.
