What are the steps that you have tried so far on this UPS?  Let us see if the UPS would run on battery by doing a cold start.  Kindly unplug the UPS from the power source and then press and hold the ON button, normally you will hear a short and a long beep.  As soon as you hear the long beep release the button.  Let us know how it would turn out.
