APC SU5000R5T-TF3 replacement

This PowerWarehouse LEADACIDSLA12-00 is a maintenance-free lead-acid cartridge designed for the APC SU5000R5T-TF3 uninterruptible power supply. It restores backup runtime when the original cells reach end of life. The sealed construction allows installation without special handling.

Replacing the RBC12 cartridge returns the UPS to its rated capacity without replacing the entire unit. The jump is worth it when runtime tests show degradation or the management card reports a battery fault. No firmware update is required after the swap.
