Replaced old 12 V, 33 AH batteries for Ferrups 3.1 UPS. Within a min from starting the UPS, those two huge capacitors (situated on the Top Rear, when you remove the Cover, furthest when you see from the front), the Caps started sounding huge arcing noise, though can't see any arc. What's is the problem? Can it do any damage to the UPS? Anyway we shut it down. Any solution to this problem?

Mike Decamp is clueless. That is not a answer. The UPS has large DC capacitors. These do go bad over time. The capacitors are required to maintain a good DC Buss and helps in assisting when putting the UPS in bypass and back online. You can not turn on the inverter with out precharging the capacitors. Get the part numbers of the caps and replace. Make sure UPS and batteries are off or you will get shocked.
Agree with epettingill, caps do go bad. Protect your eyes my friend.
I wouldn't mess w/batteries and would contact Eaton. They bought Powerware/Best Power. Lots of FERRUPS expertise:
