You're in India. What type voltages do you have there? If the battery is dead, then the UPS would make a good boat anchor unless you changed the battery. Don't know why you have it in line if the battery can't do its job.

Welcome to the forums from India! Please update your profile location information to show Non-US.
This is primarily a North American site. Not many of our members are familiar with the 220-250V 50Hz service you have there, That said, you should not be seeing power on a neutral conductor.
What are you using to test for power, and what results are you seeing?

If the load "neutral" is not tied to the source (feed) neutral then measuring voltage between load hot and ground (earth) and measuring voltage between load neutral and ground are both meaningless.

Test between neutral and a good ground. Let us know the results. For any good answers, you will need to stop fiddling with your profile and do it right. Otherwise this thread may die on the vine.

Measuring between line (hot) and neutral at the uninterruptable power supply output, if you switch the system on and get about 120 volts with some other things also plugged in (into the UPS) and turned on then everything is normal.
If you get 0 volts then check switches and breakers and (if any) a fuse inside the UPS unit.
No useful information is gathered by measuring between the UPS feed/source/input (hot or neutral) and the UPS output/load side/receptacle (hot or neutral)
