APC by Schneider Electric RBC57 Replacement Battery Cartridge
Overview
The RBC57 is a factory-new, genuine lead-acid replacement battery cartridge designed to restore full runtime capacity to compatible APC by Schneider Electric UPS systems. When a UPS begins signaling low battery health or runtime drops below usable thresholds, swapping in a fresh RBC57 returns the unit to spec without replacing the entire UPS chassis — a straightforward cost decision for deployed uninterruptible power supply infrastructure. This cartridge is the correct service path for facilities teams managing runtime-critical loads such as network closets, access control panels, surveillance NVRs, and edge computing nodes where a dead battery means an unprotected shutdown.
Compatibility
The RBC57 is a model-specific cartridge — confirm your UPS model number before ordering. APC designates each RBC part number to a defined set of UPS chassis; installing the wrong cartridge can result in improper fit, incorrect voltage, or failure to charge. Cross-reference your UPS model against APC's published RBC compatibility table on the manufacturer's site to verify RBC57 is the correct match for your unit. This cartridge is not a universal fit across the APC UPS line.
Installation Notes
RBC cartridges are designed for hot-swap or cold-swap replacement depending on the UPS model — check your unit's user manual for the correct procedure. The UPS does not need to be powered down in all configurations, but loads should be transferred or shut down before battery removal to prevent an unprotected interval. No special tools are required for most compatible models; the cartridge typically slides or clips into the battery bay. Dispose of the spent lead-acid battery in compliance with local hazardous waste regulations — many UPS battery suppliers and municipal programs accept sealed lead-acid returns. Factory-new chemistry means no pre-conditioning is required; the UPS will self-calibrate runtime estimates after a full charge cycle.
