Batteries are an important component of the UPS system. Battery service life depends on ambient temperature and discharge cycles. High‑temperature operation or deep discharge will shorten battery service life.

1.The built‑in battery of standard models is a sealed maintenance‑free lead‑acid battery. When the UPS is connected to mains power, it can charge the battery when the battery is not fully charged, whether the unit is powered on or off, and provides over‑charge and over‑discharge protection functions.

2.For battery operation, keep the ambient temperature between 15 °C and 25 °C as far as possible.

3.If the UPS will not be used for a long time, it is recommended to charge it once every three months.

4.Under normal conditions, the battery service life is 3‑5 years. Replace the battery in advance if abnormal conditions are observed. Do not replace individual batteries. Battery replacement must be performed by professional personnel.
