Replacement battery for CP685AVR-G UPS

The CyberPower RB1280 is a 12V 8AH sealed lead-acid cartridge designed to restore runtime to compatible UPS units. It arrives pre-assembled and user-replaceable so installation requires no special tools. The leak-proof construction and maintenance-free chemistry suit continuous standby service. Reusable packaging is included for returning the expired battery to a recycling centre.

Who this suits and who should look elsewhere

Owners of a CP685AVR-G or CP685AVRLCD-G UPS with a depleted internal battery will find this cartridge a direct fit. Buyers needing a different voltage, capacity or form factor cannot use this unit. It is not intended for UPS models outside the stated compatibility list.

Deciding specification

The cartridge delivers 12 volts and 8 ampere-hours in a single sealed lead-acid block measuring 3.86 by 5.94 by 2.56 inches. Matching both the voltage and the ampere-hour rating to the original battery is the critical check before purchase.
