Bring a compatible APC UPS back to full readiness with Replacement Battery Cartridge #124. This 24 Vdc, 9 Ah VRLA battery is designed to restore the performance of supported Smart-UPS SMC systems to their original specifications, making it a practical choice when the UPS chassis is still sound but the battery pack has reached end of life. For operations teams, the advantage is continuity. The cartridge is hot-swappable, so battery replacement can be performed without taking the UPS offline in the middle of a maintenance window. Its spill-proof, maintenance-free lead acid construction reduces handling overhead while supporting the dependable runtime expected from a premium replacement pack. This cartridge is compatible with SMC1000i-2U, SMC1500i-2U, SMC1000i, and SMC1500i models, giving IT teams a verified path to extend the service life of installed power protection hardware. Instead of replacing an entire UPS for a worn battery, you restore the unit’s runtime and keep the investment working. Backed by a 2-year warranty and RoHS compliance, it is a disciplined replacement for environments where uptime and procurement efficiency both matter.
