Compatible UPS Battery Kit

This RefurbUPS kit replaces the APC RBC18 cartridge with two 6V9A sealed lead-acid batteries. It is intended for administrators maintaining compatible APC UPS units that require a fresh power source.

Dual 6V9A High-Rate Cells

The single specification that determines fit is the pair of 6V9A high-rate discharge batteries inside the package. Only UPS models designed for this exact voltage and capacity combination will operate correctly with the kit.

Sustained Backup Performance

Under continuous load the high-rate discharge chemistry delivers stable voltage until the cells reach their rated capacity limit. The kit is not suited for installations that demand longer runtime than the 9Ah rating provides.
