Replacement Battery for SU1400RMX Models

The PowerWarehouse RBC25-PW is a new sealed lead-acid battery cartridge designed to replace the original RBC25 unit in APC SU1400RMXL3U, SU1400RMXLB3U and SU1400RMXLI3U uninterruptible power supplies. It restores backup runtime for connected equipment.

Physical Fit and Weight Constraints

The cartridge measures 6.0 inches long, 10.40 inches wide and 4.0 inches high, weighing 22.80 lbs. Installers must confirm the UPS battery compartment matches these dimensions and can support the mass before ordering.

Leak-Proof Sealed Lead-Acid Chemistry

The maintenance-free sealed lead-acid design prevents electrolyte leakage during operation or transport. Buyers who need a different chemistry such as lithium-ion or a higher capacity cartridge should look elsewhere.

Questions about this item

Should I choose the RBC25-PW or look for a different cartridge number for my SU1400RMXL3U?

The RBC25-PW directly replaces Battery Cartridge #25 and fits the SU1400RMXL3U, SU1400RMXLB3U and SU1400RMXLI3U models listed.

What runtime can I expect from the 22.80 lb sealed lead-acid pack once installed in my SU1400RMXL3U?

Runtime depends on the UPS load; the 22.80 lb maintenance-free pack restores the original capacity the SU1400RMXL3U was designed for.

Does the RBC25-PW use a standard connector that fits the SU1400RMXLB3U battery bay without adapters?

Yes, it matches the OEM RBC25 form factor and connector, so it slides into the SU1400RMXLB3U bay with no extra hardware.
