Replacement Battery for APC SU2200RM

This 9 Ah sealed lead-acid unit replaces the RBC11 cartridge in APC SU2200RM uninterruptible power supplies. It is built for server rooms and network closets that need a drop-in power backup refresh without changing cabling or firmware. The maintenance-free design suits administrators who want a direct swap during scheduled downtime.

Simple front-access swap with one common mistake

Installation only needs a screwdriver to open the front panel and disconnect two terminals; the new cartridge slides in the same rails. The most frequent error is reversing the red and black leads, which prevents the UPS from recognising the battery. Polarity labels on the housing match the original cartridge, so follow them exactly.
