Compatible Replacement for APC SU2200R3BX120

This maintenance-free lead-acid battery replaces the APC RBC12 cartridge number 12 in the SU2200R3BX120 uninterruptible power supply. It restores backup runtime for servers and network equipment when the original cells reach end of life. The sealed design allows installation without special handling or ventilation requirements.

Practical Limits of Lead-Acid Chemistry

Capacity diminishes gradually with each discharge cycle and accelerates in warm environments. Float voltage must stay within the UPS specification to avoid premature ageing or thermal runaway. Extended storage without periodic charging causes permanent sulphation that cannot be reversed. Users needing longer runtime or faster recharge must select a higher-capacity UPS rather than modifying this cartridge.
