No: but try a burgler alarm company if you want a sealed 12v lead acid
battery - they can be cheaper than electonics suppliers.

Also check the float charge voltage of your UPS, 0.1v can make a difference
as to whether the batteries sulphate.
We used one 6v cell in a set that was gererating 240v (ish) DC in order
to get the correct charge voltage.
