Two-pack replacement cartridge for APC SUA1000RMI2U

This PowerWarehouse 2XRBC23SLA235 kit supplies two 12 V lead-acid cartridges numbered 23 that are guaranteed compatible with the APC SUA1000RMI2U uninterruptible power supply. The pair restores the original runtime and load support for the 1000 VA unit. Installation follows the standard hot-swap procedure for that model.

Replaces worn original batteries in the same UPS

When the existing cells no longer hold charge or the UPS reports a battery fault, this two-pack returns the system to factory-spec backup time. It is not suited for units that require a different cartridge number or voltage, and it does not increase capacity beyond the original design.
