these areas.
UPS Regular Inspection

Regularly check the UPS every half year and inspect:
1. Whether the UPS, LEDs, and alarm function are operating normally.
2. Whether battery voltage is normal. If battery voltage is too high or too low,
find the root cause.

12.2 Batteries

The RT series UPS uses sealed lead-acid batteries. Though the typical battery
life cycle is 3~5 years, the battery life depends on the temperature, usage, and
charging/ discharging frequency. High temperature environments and high charging/
discharging frequency will quickly shorten the battery life. The UPS does not require
user maintenance; 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.
