APC SU5000RMT5U compatible replacement

This PowerWarehouse LEADACIDSLA12-05 is a maintenance-free sealed lead-acid cartridge built for the APC SU5000RMT5U uninterruptible power supply. It restores backup runtime when the original cells have reached end of life. The unit arrives new and ready for installation.

Replaces exhausted RBC12 cartridge #12

Swapping this cartridge returns the UPS to its rated runtime without replacing the whole chassis. The upgrade is worth it when battery alarms sound, self-tests fail or runtime has dropped below operational needs. It is not suited for systems that require a different cartridge format or voltage configuration.
