Keep compatible APC Back-UPS systems performing to original specifications with Replacement Battery Cartridge #17. The RBC17 arrives as a complete, tested, and charged battery set, so replacement is fast and predictable when runtime starts to fall. Built around a 12 V 9 Ah sealed lead-acid design, it is intended for APC BV, BX, BVX, BE, and BN models that need a direct-fit cartridge rather than a generic battery swap. For operations teams, the value is in consistency. Hot-swappable and user replaceable, the cartridge supports maintenance without unnecessary downtime. That matters when you are protecting desktops, network edge gear, point-of-sale systems, or small server-room loads that cannot wait for a full shutdown. The maintenance-free construction reduces handling overhead, while APC testing helps ensure the replacement restores UPS behavior as expected. RBC17 also includes a 2-year return-or-replace warranty and is RoHS compliant. For organizations that prefer OEM-fit parts over lower-cost substitutes, it delivers the compatibility, serviceability, and accountability that keep support calls and risk to a minimum.
