Direct replacement for APC SUA3000R2IX38

This 12V 5Ah sealed lead-acid battery replaces the APC RBC43 cartridge number 43. It is built for the SUA3000R2IX38 uninterruptible power supply and fits the original battery compartment without modification. The maintenance-free design means no fluid checks are required during its service life.

Six-unit cartridge restores full runtime

The pack contains six matched cells pre-wired into the cartridge frame so the UPS regains its factory backup capacity in a single swap. No separate cables, connectors or mounting hardware are included because the original hardware is reused. Installation is limited to removing the old cartridge and inserting this one.
