I tried using deep cycle lead-acid batteries in a couple
of 2KVA units. They were perfectly capable of holding up the
UPS (be sure your UPS has adequate cooling -- some don't, on
the assumption that the batteries will go flat before the
temperature rise in the inverter gets out of hand). However,
the charge characteristics of lead-acids vs. gelled electrolyte
cells confused the hell out of the charger in the UPS -- it would
routinely boil off the batteries.
I ended up switching back to gel cells -- although I was able to
find ones from Panasonic which were the same physical size but
twice the capacity, which was kinda nice :-)
