Compatible UPS battery pack

This two-pack of 12 V lead-acid cartridges is built for the APC Smart UPS 1400 RM XL 5U 208 V. It restores runtime for rack-mounted units that protect servers and network gear. The batteries arrive new and are guaranteed 100 % compatible with the original equipment. Each cartridge carries a one-year replacement warranty.

Direct cartridge swap

The pack replaces the original RBC11 cartridge set without rewiring or firmware changes. It is the right choice when the existing cells no longer hold a charge or when preventive replacement is due. Buyers who need a different voltage, form factor or connector type should look elsewhere.

Questions about this item

Will the RBC11 cartridge fit inside my APC Smart-UPS 1400 RM XL 5U 208V chassis?

Yes — the cartridge is built to match the original RBC11 form factor so it slides directly into the 5U rack-mount UPS battery compartment.

What is the correct way to install the two 12 V modules and the step most people miss?

Insert each module into the cartridge tray, connect the red lead to the positive terminal and the black lead to the negative terminal, then secure the retaining strap — the step often missed is fastening that strap before closing the UPS door.
