12 V 5 Ah UPS cartridge for APC SUA2200RMI2U

This sealed lead-acid cartridge replaces the APC RBC43 unit in the SUA2200RMI2U uninterruptible power supply. It delivers 12 volts and 5 ampere-hours in a maintenance-free package. The battery arrives new and ready for immediate installation. It suits administrators who need a direct drop-in spare for that specific UPS model.

Two units form the complete internal set

The SUA2200RMI2U requires two of these cartridges to restore full runtime. Installing the pair frees the UPS from degraded backup capacity without modifying wiring or firmware. No additional hardware or configuration changes are needed. Buyers who need a different voltage, capacity or form factor will not be served by this cartridge.

Sealed lead-acid chemistry runs cool under normal UPS loads; no active cooling is required in the APC SUA2200RMI2U chassis.
