Drop-in replacement for CP1000AVRLCD

The CyberPower RB1290 is a new sealed lead-acid cartridge built to restore runtime on the CP1000AVRLCD uninterruptible power supply. It arrives pre-assembled so the single 12 V 9 Ah cell can be swapped without tools or wiring. The 18-month warranty covers the unit from installation.

Leak-proof sealed case and recycling pack

The battery is housed in a maintenance-free enclosure measuring 3.86 x 5.94 x 2.56 inches and weighing 6.06 lbs. Its sealed construction prevents electrolyte leaks in any mounting orientation. The shipping carton doubles as a reusable container for returning the expired cell to a recycling centre.

12 V 9 Ah capacity restores original runtime

This capacity matches the factory specification for the CP1000AVRLCD, so the UPS will deliver the same backup time it did when new. Systems that require a different voltage or amp-hour rating will not accept this cartridge.
