Every UPS I've used, from cheap home ones, to full rack APC units, I've found that the batteries last about 4-5 years. The home unit needed $40 for new batteries (same OEM, not APC-branded.) They lasted 8 years, which I thought was pretty good. (And, yes, I do test it every year or sooner.) It's pretty cheap insurance and you can use the power in an emergency for things like inflating an air mattress if you have to sleep in the basement due to tornado warnings (yes, I've don that!)
