Compatible replacement for APC SUA2200R2X147

This 12 V, 5 Ah sealed lead-acid battery is built as a direct replacement for the APC SUA2200R2X147 unit and matches the RBC43 cartridge #43 specification. It suits administrators who need a maintenance-free power source for rack-mount UPS systems in server rooms or network closets.

Sustained float operation in rack environments

The valve-regulated design delivers steady voltage during extended discharge cycles typical of UPS float service, avoiding the voltage sag seen in short-burst applications. It is not suited for cyclic deep-discharge use or for installations that require hot-swap modules with integrated monitoring circuitry.
