Maintain backup power without replacing the entire UPS. The CyberPower RB1290X6A replacement battery cartridge is designed for OL2.2-3KVA UPS systems, giving infrastructure teams a direct path to restore runtime and keep protected loads online during utility interruptions.

This cartridge is specified as a 12 V battery solution and is intended for the OL2.2-3KVA platform, which helps ensure fit and compatibility in environments where predictable serviceability matters. For procurement teams, the value is straightforward: replace only the battery assembly, preserve the installed UPS investment, and extend the useful life of the power protection system. An 18-month warranty provides added assurance for scheduled refresh cycles and maintenance planning. For data closets, branch offices, and edge deployments, this replacement battery cartridge supports a practical, lower-friction approach to UPS upkeep while helping critical systems stay protected when power quality drops.
