APC RBC48 – Replacement Battery Cartridge for Smart-UPS

Overview

The APC RBC48 is a sealed lead-acid replacement battery cartridge for select APC Smart-UPS models. IT administrators, data center engineers, and network technicians use this cartridge to maintain uninterrupted backup power for servers, storage devices, and networking equipment. The RBC48 ensures critical infrastructure remains operational during utility outages and supports controlled shutdown procedures when the original UPS battery reaches end-of-life.

Each RBC48 unit delivers a nominal 12V DC output and features hot-swappable design, allowing replacement without powering down the UPS or connected systems. Compatible Smart-UPS units automatically detect the cartridge, providing runtime monitoring, battery health reporting, and end-of-life notifications through the UPS management interface.

The cartridge is suitable for rack-mounted and tower UPS deployments, commonly installed in server rooms, branch office racks, or edge IT cabinets. Its compact form factor allows straightforward installation while maintaining proper airflow and clearance within the UPS chassis.

UPS management integration provides real-time monitoring, runtime estimation, and proactive maintenance notifications, reducing the risk of unexpected UPS failure and ensuring continuous protection for connected equipment.

The RBC48 is not compatible with non-APC UPS systems, high-voltage industrial UPS units, or chemistries other than sealed lead-acid. For deployments requiring extended runtime beyond the RBC48’s capacity, multiple cartridges or external battery packs designed for higher-capacity Smart-UPS models should be used.
