CyberPower RB12120X2B UPS Replacement Battery Cartridge

The CyberPower RB12120X2B is a replacement battery cartridge that restores full backup power to compatible CyberPower UPS systems without requiring a complete unit replacement. It arrives with two sealed lead-acid batteries rated at 12 volts and 12 amp hours, already wired and secured, so installation is as simple as removing the old module, sliding this one into place, and reconnecting the leads. Most users can complete the swap within minutes, limiting downtime for critical equipment.

Designed for home offices, small businesses, and network closets, the cartridge features a leakproof housing that guards nearby electronics against accidental spills. The design is maintenance free, eliminating the need for fluid checks or refills once installed. CyberPower ships the cartridge in reusable packaging that doubles as a safe container for returning the spent batteries to a recycling center, making responsible disposal straightforward.

The RB12120X2B meets or exceeds the original factory specifications for the CyberPower PR1000LCD and PR1000LCDTAA models, delivering the same reliable runtime you expect from a new UPS. An 18-month limited warranty underscores CyberPower’s commitment to quality and provides peace of mind long after installation.
