Overview

The APC APCRBC118 is a sealed lead-acid replacement battery cartridge designed for APC Smart-UPS X-series systems and external battery packs. It is used by IT teams and data center operators to restore UPS runtime and maintain consistent backup power for critical loads.

This cartridge provides a 120V DC output with an internal multi-battery configuration, ensuring stable power delivery during outages. It is factory-assembled with connectors and enclosure, allowing seamless integration with APC’s intelligent battery management system. The unit supports hot-swappable replacement, enabling battery changes without interrupting connected equipment.
