American Battery Company RBC27 UPS Replacement Battery

Direct UPS Power Replacement

The American Battery Company RBC27 is a ready-to-install replacement battery cartridge for compatible APC Smart-UPS units. It supplies eight sealed lead-acid cells rated at 12 volts and 7 amp-hours each, delivering the runtime needed to protect critical data during a blackout. The cartridge arrives new and fully assembled with cables and connectors included for immediate plug-and-play deployment. It is designed for administrators who need a cost-effective way to restore UPS backup capacity without replacing the entire unit.

Rack-Mount Cartridge Integration

The RBC27 fits directly into the battery bays of SU2200RMXL3U, SU2200RMXLI3U, SU3000RMXL3U, SU3000RMXLI3U and SU48RMXLBP3U models, while the SU48R3XLBP requires two cartridges for full operation. Its 4.25 by 22.5 by 6.5 inch form factor matches the original chassis dimensions so no rack rearrangement is necessary. Hot-swappable design lets technicians exchange the cartridge while the UPS remains online, freeing the maintenance window for other tasks. Reusable packaging is provided to return the spent cells for recycling.

Sustained Discharge Reliability

Eight maintenance-free 12V 7Ah cells are wired to support the extended runtimes demanded by 2200 VA and 3000 VA UPS loads during prolonged outages. The sealed construction prevents electrolyte loss over years of float service, keeping voltage stable throughout the discharge curve. At 54.00 lbs the cartridge remains manageable for single-person replacement even in dense rack rows. This chemistry is not suited for applications requiring rapid cyclic discharge or lithium-ion energy density.
