Check the cartridge, connector and UPS model
A battery voltage or shared base cell alone does not establish cartridge compatibility. Compare the complete assembly, cable routing, connector keying, polarity and mounting arrangement. Follow the UPS manufacturer’s replacement procedure; do not assume that replacement while powered is permitted.
