Took off the UPS this battery just a few days ago. It is a FB N-170, still gives for an hour backup (3 old fans and 4 energy savers). You might try changing the water and get it recharged?this might increase the backup time, the battery never went for recharged or gravity check since i bought early last year.
What I am asking?.well the battery shops takes a dead battery of this size for Rs.3500/-, so that is what I will take. Just posting this ad for the sake that it might be useful to someone who needs such a battery.
I live in G-9/4 Islamabad and anyone who wants to purchase this has to pick it up from here.
