Compatible replacement for APC SU2200R3X106

The PowerWarehouse LEADACIDSLA12-11 is a maintenance-free sealed lead-acid battery cartridge designed to replace the APC RBC12 cartridge #12 in the SU2200R3X106 UPS. It provides a direct-fit power source for server and network equipment protection.

Sealed lead-acid chemistry requires upright mounting

The battery uses valve-regulated lead-acid technology that must remain upright to prevent electrolyte leakage. Runtime decreases as cells age and capacity fades, so scheduled replacement is necessary. No user-serviceable parts are inside the sealed case.

Questions about this item

Should I pick the 11 Ah or 12 V version for my APC SU2200R3X106?

This unit is a single 12 V, 11 Ah cartridge that matches the RBC12 specification, so there is no separate capacity option to choose.

What does the 11 Ah rating mean when the battery is installed in the UPS?

It indicates the total charge the cartridge can deliver at its rated voltage, determining how long the UPS can support connected equipment during a power outage.
