I have a 600VA ups with a 100Ah battery. I merely get about two hours of backup when running on batteries at half the load. I had both the battery and UPS replaced under warranty and its the same.There is a scheduled power cut for exactly 2 hours everyday, so that gives 22 hours without any interruptions for the battery to charge which I believe should suffice .

The people at APC tell me that I should get atleast 4.5 hours of backup running at about half the load(300VA/~180 Watts) and 2 hours at full load(600VA/~360 watts). APC has load indicators to indicate the load when running on the batteries
I m totally clueless on what to do next ? The electrical appliances connected are just a couple of tubelights and fans.
How would I able to diagnose if something is wrong in the wiring configuration ? Thats the only thing left for me to diagnose, but where and how do I start ?
Any thoughts would be appreciated
Anjay.
