Hi, depending on the ups you can extend the leads and connect them to any size battery of the same voltage as the usp battery. I have done this with a UPS with a 6V battery and hooked the leads to a group of 6V RV batteries. Then the 1000 VA UPS ran for 10 hours instead of 30 minutes. This is commonly done for phone systems. If using multiple batteries, install a fuse between the positive connections of the ups to first battery, fuse between first and second battery. The batteries are all in parallel.
