Compatible APC Back-UPS 650 battery kit

This replacement kit supplies a factory-fresh 12V 12A battery cartridge designed for the APC Back-UPS 650 model BK650MUC. It matches the RBC4 specification and arrives new, ready to restore backup runtime for home-office or small-business UPS units.

Check UPS model and battery bay access

Before ordering, confirm that your UPS carries the exact model number BK650MUC so the cartridge fits the internal compartment. Verify that the battery door can be opened and that the existing unit uses a single 12V 12A block rather than a different voltage or capacity. Ensure you are comfortable disconnecting the old battery and connecting the new one following the manufacturer safety instructions.
