Did your UPS display "Battery disconnected" or did it display "Battery Failure"? If it was "Battery Failure", for some reason the Powerware 9120 will take almost 18 hours after plugging in to power after battery replacement to correct the Battery Failure indication. Charger has to charge up the batteries, followed by an automatic battery test by the UPS. If the indication was "Battery Disconnected", you will need to check the internal fuses to see if they are blown. If the UPS keeps blowing fuses, it will require a board repair.

Here is the 9120 documentation page but Eaton generally does not publish circuit diagrams for smaller UPSs like this. Some people may be technical enough to take a UPS apart but most aren't and it can be very dangerous. I suggest you contact the Eaton hardware support forum.
