What This Cartridge Replaces

The APC RBC12 is a direct-fit replacement cartridge for compatible Smart-UPS units. It restores runtime to factory levels without rewiring or configuration changes. Facility managers and IT staff can swap it during a scheduled maintenance window.

Hot-Swappable Plug-and-Play Design

The cartridge slides into the UPS while the load remains powered, so connected equipment never drops offline. No tools are required and the unit recognises the new cells immediately. This keeps critical servers, network gear or point-of-sale systems running during the swap.

Sealed Lead-Acid Chemistry Runs Cool

Maintenance-free sealed lead-acid cells with suspended electrolyte produce minimal heat and no audible fan noise during normal float charge. The leak-proof construction prevents acid migration even if the cartridge is tilted. Expected service life is three to five years under typical office ambient conditions.

Questions about this item

How long will the 3-5 year expected life actually last once the cartridge is installed in my UPS?

The sealed lead-acid cells are rated for three to five years of standby service; actual runtime depends on load, temperature and discharge depth.

Does the plug-and-play cartridge use a standard connector that limits voltage or current?

The cartridge connects through the UPS's proprietary hot-swap interface, which is keyed to the correct voltage and current for this model.

Will the 3.8 by 10 by 6 inch stand-alone stack fit in the battery compartment of my Smart-UPS?

The cartridge measures 3.8 x 10 x 6 inches and weighs 44.00 lbs, matching the original RBC12 form factor for direct replacement.
