Direct UPS Replacement

The ABC RBC2 is a 12 V 7 Ah sealed lead-acid cartridge designed to restore runtime to compatible APC UPS units. It arrives ready to install with cables and connectors included for plug-and-play replacement. Maintenance-free construction eliminates the need for periodic fluid checks. Hot-swap support lets you change the battery without powering down connected equipment.

Capacity And Runtime Limits

A single 12 V 7 Ah cell delivers enough reserve for typical desktop loads to save work and shut down safely during a blackout. Runtime scales with the UPS model and attached load; heavier configurations will exhaust the capacity faster. The cartridge is not suited for extended backup scenarios that demand higher amp-hour ratings. Users needing longer runtimes should verify whether their UPS accepts larger-capacity cartridges.

Tab Size .25 Compatibility

The .25 inch tab dimensions determine whether the cartridge mates correctly with the UPS battery connector. Confirm the tab measurement on the existing battery before ordering to avoid a mechanical mismatch. Units listed in the compatibility table share this tab size, but BK200 and BK200B models require manual verification. An incorrect tab size prevents electrical contact even if voltage and capacity match.

Questions about this item

Will the RBC2 fit my BK500 UPS without rewiring?

The RBC2 uses the same 0.25-inch tab connectors as the BK500, so it plugs straight into the existing battery compartment.

How can I confirm the new RBC2 is delivering 12 volts after installation?

Measure the terminals with a multimeter; a healthy sealed lead-acid cell reads about 12 volts when the UPS is on mains power.

Does the box include the recycling bag for my old battery?

Yes, reusable packaging for returning the spent battery is supplied with the RBC2.
