Keep essential infrastructure running longer when utility power drops. This APC Smart-UPS XL 48 V rack-mount battery pack adds 1,728 VAh of extended runtime capacity to compatible Smart-UPS XL systems, giving IT teams more time to ride through outages, complete graceful shutdowns, or wait for generator transfer. It is designed for the SUA2200RMXL3U, SUA2200RMXLI3U, SUA3000RMXL3U, and SUA3000RMXLI3U platforms, so it fits cleanly into existing APC environments without forcing a redesign of the power stack. The 3U rack form factor preserves cabinet organization while the hot-swappable design helps reduce maintenance disruption. Lead-acid, spill-proof, maintenance-free construction keeps ownership simple, and the 48 V DC output aligns with the Smart-UPS XL battery architecture for predictable performance. For teams protecting servers, storage, and network gear, this battery pack adds the runtime margin that lower-capacity replacements cannot match. With a 2-year repair-or-replace warranty and RoHS compliance, it is a practical choice for environments that need dependable backup power and straightforward lifecycle management.
