Batteries

The HPH series UPS uses sealed lead-acid batteries. 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. Please follow the suggestions

below to ensure a normal battery lifetime.

1. Keep usage temperature between 15°C~25°C.

2. When the UPS needs to be stored for an extended period of time, the batteries must be

recharged once every three months and the charging time must not be less than 24 hours

each time.

Fans

Higher temperatures shorten fan life. When the UPS is running, please check if all of the fans work

normally and make sure if the ventilation air can move freely around and through the UPS. If not,

replace the fans.

NOTE:

Please ask your local dealer or customer service for more maintenance information. Do

not perform maintenance if you are not trained for it.
