The batteries in a UPS are lead-acid, same as a car battery. They do
wear out after a while. I have 4 UPSs between home and office. I've
replaced batts in 2 of them, I'd say averaging 4-5 years of use.
One way to test it is pull the UPS's plug out of the wall. If the computer
doesn't stay powered up, you need a new battery. Theoretically,
something else could be wrong with the UPS, but it's very unlikely.
I bought my replacement batts on Ebay.
