Factory Fresh Replacement Battery for Back-UPS Pro

This factory fresh replacement battery kit is compatible with the APC Back-UPS Pro 420 (BP420SI). It consists of one 12V7A battery designed to restore backup power to the UPS unit. The cartridge matches APC RBC2 specifications for a direct fit. It is ready for immediate installation in compatible units.

Practical limits of sealed lead acid chemistry

Sealed lead acid batteries lose capacity over time and with repeated deep discharges. Runtime decreases as the cells age and internal resistance rises. The unit requires periodic replacement to maintain the original backup duration. Operating temperature extremes accelerate the aging process and reduce available power.
