Lalit,

How old Is the UPS? Has the battery ever been replaced in the UPS? What lights are on the front of the UPS when it is plugged into the wall outlet? Had the UPS been supporting the connected load during power failure before?

Do you have other Identical working unit? If so, swap the batteries and check if the unit in works fine after power failure.
