BTI RBC55-SLA55-TAA 12V 4-Cell Lead Acid UPS Battery

This 12V 4-cell lead acid battery serves as a direct replacement for APC RBC55 units. It is built for server rooms and network closets that rely on compatible Smart-UPS models for continuous power protection. TAA compliance makes it eligible for federal procurement schedules.

Replaces RBC55 in SUA3000.

The battery fits SUA3000, SUA5000RMI5U and SUA5000RMT5U Smart-UPS systems along with DLA2200 and DLA2200I rackmount models. Swapping the old RBC55 restores full runtime when the original cells no longer hold charge. It is not suited for UPS models that require a different voltage or cell count.

Drop-in installation with standard terminal layout

The pack uses the same form factor and connector orientation as the factory RBC55 so no wiring changes are needed. Common issues arise if the UPS firmware does not recognise the new pack after installation; a manual self-test or calibration cycle usually resolves the detection error.
