Folks, I have an APC Back-UPS 600VA rating. It works for 1 hr wothout supply. I wanna extend the battery backup time upto 4-5hrs. Will that work if I install a new battery rated 12V, 28AmpHr rating in parallel connection to the existing one.? The inbuilt one has 12V, 7AmpHr rating ?
Actally I have already done this now....and just waiting for to see the results....its past 1 week now...and everythings is going fine..!
What are your predictions about this?
Is this fine ? Can I use such a combination....for longer time...or CAN this HARM the UPS in future ?

My main concern is the charging circuit...if it can charge both batteries..?
I am working for DELL as a Technical Engineer...and still need your advice..!

Okay, voltages in the ups are safe but the amperages can kill. My recomendation would to go buy a new one rather that messing around inside. Ask dell, if batterys are done wrong they can overheat and cause fires or even explode spreading battery acid everywhere.

if it's in parallel it cannot harm the ups..
