Replacement cartridge for APC SU2200BX120

This PowerWarehouse lead-acid cartridge replaces the APC RBC11 unit used in the SU2200BX120 uninterruptible power supply. It is a maintenance-free sealed battery designed for direct installation. The product suits administrators maintaining that specific UPS model.

Sealed lead-acid chemistry limits

Sealed lead-acid cells self-discharge during storage and lose capacity after repeated deep cycles. They cannot be fast-charged like lithium chemistries and must be recycled at end of life. Runtime scales with the attached load, so heavier equipment reduces available backup time.
