Ready replacement for Back-UPS 500

This factory-fresh battery kit is built to fit the APC Back-UPS 500 (BK500EI) and restores runtime for home-office or small-business desktops. It contains one 12 V 7 Ah sealed lead-acid cell that matches the original RBC2 specification. The kit arrives new and ready to install without tools.

Steady voltage during extended outages

Under sustained load the sealed lead-acid chemistry delivers a stable 12 V output until the UPS initiates its shutdown sequence, avoiding the voltage sag seen in short-burst tests. The single-cell design keeps internal resistance low so the UPS can hold connected equipment through longer power cuts. It is not suited for units that require multiple batteries or higher-capacity cartridges.
