Direct UPS Replacement

The ABC RBC4 is a 12 V maintenance-free sealed lead-acid cartridge designed for hot-swappable installation in compatible APC UPS units. It delivers a 12000 mAh capacity and targets users who need to restore runtime without replacing the entire UPS.

Guides and Recycling Included

The package supplies a replacement battery cartridge alongside an installation guide and a recycling guide. These documents walk through the swap procedure and explain how to return the spent unit, reducing downtime and simplifying disposal.

Simple Swap With Fit Checks

Installation involves removing the old cartridge and inserting the new one, a process the guide illustrates step by step. Compatibility is limited to the listed APC models such as BP650S, BK650M and SU650, so builders using other UPS units or requiring different voltages cannot use this cartridge.
