What This Kit Contains

The RefurbUPS RBC3 compatible kit supplies two 6V 12A sealed lead-acid batteries wired together as a direct replacement for APC RBC3 UPS units. It is intended for administrators who need to restore runtime on existing UPS hardware without replacing the entire appliance. The kit arrives factory-fresh and includes printed installation instructions so the swap can be completed in-house.

Interface and Installation Limits

The batteries connect using the original wiring harness already present in the UPS, so no new cabling or connector adapters are required. Physical dimensions match the OEM pack, allowing the kit to fit the same battery compartment without modification. Installation is limited to UPS models that accept the RBC3 form factor; units with different voltage or connector layouts cannot use this kit.

Capacity and Runtime Headroom

Two 12 Ah cells deliver the rated amp-hour capacity the UPS firmware expects, supporting typical server loads for the duration specified by the original manufacturer. Runtime scales with attached load; heavier draw will exhaust the pack sooner while lighter loads extend it proportionally. The kit does not increase capacity beyond the original specification, so environments needing longer backup must add external battery modules or upgrade the UPS itself.

Questions about this item

Should I choose a single battery or the kit with two 6V12A units?

This kit supplies exactly two 6V12A SLA batteries; the APC RBC3 compartment requires both cells wired in series to reach the correct voltage.

What does the 12 Ah rating deliver in my UPS?

At 12 ampere-hours each, the pair supports high-rate discharge for the runtime APC specifies for RBC3-compatible units under typical load.

How does the existing wiring harness connect to these batteries?

The kit reuses your current harness; the two 6V12A batteries arrive ready to link in series using the original connectors and included instructions.
