Protect uptime with a genuine APC Replacement Battery Cartridge built for compatible UPS systems that depend on the correct battery profile and physical fit. APCRBC105 is designed to restore battery-backed runtime without the uncertainty of generic replacements, helping keep shutdown windows controlled and service interruptions contained. For operations teams, the advantage is consistency. A genuine APC cartridge supports the same replacement workflow your maintenance staff already knows, while helping preserve the UPS behavior expected in production, edge, and branch environments. That matters when the battery is part of a larger continuity plan, not just a consumable. This cartridge uses lead acid chemistry and is backed by a 2-year limited warranty. It is also RoHS compliant and environmentally friendly, which helps satisfy standard procurement requirements. If you are maintaining APC UPS units across multiple sites, APCRBC105 gives you a straightforward path to keep protected loads ready for the next outage.
