Problem with the same unit... Hardly 30 minutes backup now!

I barely managed to get the UPS replaced last time around. The new unit is giving problems now. Backup time is now less than 30 minutes. I would now have to go through the entire ordeal once again.



And it is not even recharging right now. Called APC. It would take them 2 days to send me an engineer. And this is when they have a service station just walking distance from my home.
