APC RBC57 – Replacement Battery Cartridge 12V SLA

Overview

The APC RBC57 is a sealed lead-acid replacement battery cartridge designed for APC Smart-UPS RT systems. It is used by IT teams and data center operators to restore original UPS runtime and maintain reliable backup power for critical infrastructure.

This cartridge delivers a 12V SLA configuration with approximately 432VAh capacity, ensuring stable output during outages. It comes fully assembled with internal connectors and is engineered for seamless integration with APC UPS battery management systems. The unit supports hot-swappable replacement, allowing battery changes without powering down connected equipment.

It is typically deployed in rack-mounted UPS systems within data centers, network closets, and edge environments where uptime is critical. The enclosed cartridge design reduces installation complexity and minimizes maintenance effort.

This battery is designed strictly for compatible APC Smart-UPS RT models (e.g., SURTA series). It should not be used in third-party UPS systems or as a loose battery replacement due to compatibility and safety constraints.
