APC SUA3000R2X145 compatible battery pack

This PowerWarehouse 2XRBC43SLA4321 pack supplies two 12 V lead-acid cartridges built to fit the APC SUA3000R2X145 UPS. Each cartridge matches the original equipment specifications for direct replacement without modification. The pair restores runtime for rack-mount units that protect servers and network gear.

Sustained load performance of the 43 series

Under continuous discharge the 12 V chemistry delivers steady voltage until the cells reach their cut-off point, avoiding the sharp drop seen in short bursts. The dual-cartridge layout shares current evenly so neither cell overheats during extended outages. Capacity remains stable across repeated cycles when the UPS charging routine is maintained. Buyers needing longer runtime than the standard pair provides must add external battery modules.
