Purpose-built replacement cartridge

This CyberPower RB1290X10 cartridge supplies ten sealed 12V/9AH batteries pre-wired for CyberPower OL8-10KVA UPS units and the BP240V50ART3U extended battery module. It arrives ready to install without additional assembly or electrolyte handling. The pack targets IT teams maintaining critical power infrastructure in server rooms or network closets.

Compatibility-locked fit

The single specification that decides fit is the exact model match: this cartridge is certified only for the listed OL8-10KVA UPS models and the BP240V50ART3U EBM. Using it in any other UPS chassis or battery module will void the certification and risk improper voltage or connector alignment. Buyers who need a different voltage, capacity or form factor must select the cartridge specified for their exact UPS model.

Pre-assembled convenience

The batteries ship pre-assembled into a single cartridge with an included installation guide, eliminating the need to wire individual cells or torque terminals on site. Maintenance-free sealed construction removes periodic fluid checks from the service schedule. An 18-month warranty covers the cartridge from date of purchase.

10-cell pack 12V 9AH

The ten-cell 12V/9AH configuration restores the original runtime and load capacity of the supported UPS and EBM units. No software, firmware or management accessories are bundled; the cartridge is a pure hardware replacement. Buyers who want runtime monitoring must rely on the UPS built-in management card or network interface.
