Compatible Smart-UPS Models

This APC RBC55 replacement battery cartridge fits Smart-UPS units including SMT2200, SMT3000, SMT2200C, SMT200US, SMT3000C, SUA2200 and SUA3000. It restores backup power for servers, network gear and workstations that rely on those UPS models. The cartridge is hot-swappable so the UPS stays online during installation.

816 VAh Capacity

The single figure that decides fit is the 816 VAh rating, which must match the original cartridge specification for the listed UPS models. A different capacity will not provide the correct runtime or charging profile. This cartridge contains one sealed lead-acid battery assembly rated at that exact capacity.

Maintenance-Free Sealed Design

The battery uses maintenance-free sealed lead-acid chemistry with suspended electrolyte, making it leakproof and spill-proof in normal operation. No watering or electrolyte checks are required during its expected three to five year service life. The 53.40 lb cartridge measures 6.8 by 5.6 by 7.2 inches and installs without tools.

Questions about this item

How long will the 816 VAh capacity keep my UPS running during a power cut?

Runtime depends on the load attached to the UPS; the 816 VAh rating shows total energy storage, not a fixed minutes figure.

Does the RBC55 use a standard connector that fits my Smart-UPS without adapters?

Yes, the cartridge is designed as a direct hot-swappable replacement for the listed Smart-UPS models.

Will the 173 mm high cartridge fit inside my existing UPS chassis?

The unit measures 173 mm high, 142 mm wide and 7.2 inches deep; compare those dimensions with your UPS battery compartment.
