APC RBC11 Replacement Battery Cartridge - 816 VA h UPS Battery

Overview

The RBC11 is a replacement battery cartridge intended for use in select APC UPS systems where internal battery cells require service. It restores backup runtime capacity by replacing depleted sealed lead-acid cells with a maintenance-free pack verified to meet OEM specifications.

This battery cartridge is comprised of two sealed lead-acid cells configured to deliver approximately 816 VA h of energy storage at 24 V DC (two 12 V cells in series). The design supports hot-swap service, enabling battery replacement without powering down the UPS load when the UPS supports hot-swap battery modules.

Physically the RBC11 is a compact pack designed for vertical or shelf mounting inside compatible UPS chassis or external battery cabinets. Its sealed lead-acid construction requires no routine maintenance.

Battery life expectancy under normal operating conditions is 3 to 5 years, depending on ambient temperature and duty cycle. Thermal stress accelerates degradation; consistent environment control increases service life.

This component only provides energy storage and does not include power conversion, regulation, or control functions. It must be installed in a UPS or battery cabinet designed for RBC11 packs. It is not suitable as a standalone UPS or as a direct-connect DC UPS replacement.
