Compatible Replacement for APC SUA750IX38

This two-pack supplies 12 V lead-acid cartridges numbered 48 that are guaranteed to fit the APC SUA750IX38 UPS. Each unit is built to match the original equipment specifications so the UPS can resume normal operation immediately after installation. The pack contains two cartridges to complete the full battery string in one purchase.

Steady Voltage Delivery Under Continuous Discharge

During extended runtime events the lead-acid chemistry maintains a stable 12 V output without the sharp voltage sag seen in short-burst tests. Internal resistance stays consistent as the cells discharge, letting the UPS inverter draw predictable current until the low-battery threshold is reached. The matched pair ages at the same rate, preventing cell imbalance that would otherwise shorten the overall service life.
