Schneider Electric APCRBC123 Battery Cartridge

The Schneider Electric APCRBC123 is a replacement battery cartridge designed for compatible APC uninterruptible power supply units. It restores backup runtime for connected equipment when the original cells reach end of life. This cartridge suits IT administrators and home-office users maintaining existing APC UPS hardware.

Installation and common issues

The cartridge is built for tool-free insertion into the UPS battery compartment following the manufacturer's replacement procedure. Polarity must match the connector orientation; forcing the plug can damage pins or the housing. Old cartridges contain sealed lead-acid cells and must be recycled according to local regulations.

Compatibility checks before ordering

Verify the exact UPS model number against the APC compatibility list for Replacement Battery Cartridge No. 123 before purchase. Confirm the physical dimensions and connector type match the unit currently installed. Ensure the UPS firmware supports user-replaceable battery detection if that feature applies to your model.
