Compatible UPS Replacement Battery

This 12V 5Ah sealed lead-acid battery replaces the RBC43 cartridge used in APC SUA3000RMl2U uninterruptible power supplies. It is built for server-room and network-rack environments that need a direct drop-in power source. The maintenance-free design suits administrators who want a ready-to-install unit without electrolyte handling.

Simple Cartridge Swap Installation

The battery ships as a pre-wired cartridge so installation only requires opening the UPS front panel, unplugging the old pack and sliding the new one into the same rails. Polarity-matched connectors prevent reverse-connection errors. The main risk is forgetting to recycle the spent battery, which is mandatory for lead-acid cells.

The UPS will run a self-test and display normal voltage once the new cartridge is seated and the unit is powered on.

Does the LEADACIDSLA43-13 package include the RBC43 cartridge housing or just the bare cells?

It ships as a complete RBC43 cartridge #43 ready to slide into the SUA3000RMl2U; no extra parts are required.
