8. Storage and Maintenance

8.3 Battery

S3M-Series UPS systems use sealed lead-acid batteries. The battery life depends on operating 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 operating temperature between 32°F to 104°F.

2. For optimum battery performance and life, operate at a regulated 77°F.

3. 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.

8.4 Fan

Higher temperatures shorten fan life. When the UPS is running, ensure all fans are working normally and make sure air

can move freely around and through the UPS. If not, replace the fans.

Note: Contact Technical Support for more maintenance information. Do not perform maintenance if you are not qualied to do so.
