Overview

The APC APCRBC143 is a sealed lead-acid replacement battery cartridge designed for APC Smart-UPS X and extended runtime systems. It is used by IT teams and data center operators to restore UPS runtime and maintain reliable backup power for critical infrastructure.

This cartridge delivers a 120V DC output using a multi-battery internal configuration, providing stable and consistent power during outages. It is factory-assembled with connectors and enclosure, ensuring seamless integration with APC’s battery management system. The unit supports hot-swappable replacement, allowing battery changes without shutting down connected equipment.
