I think the batteries are lead acid just like car batteries, which last 6-7 years or more, and in the winter operate at low temperatures.
Now for a UPS that is at room temperature all the time, and only operates several times a year, I would expect a life span of around 10 years or so, but I recall reading here that they only last a few years. Why is that?
I bought my first UPS a year ago, then a second one, and about every six month I unplug the cord form the wall and run them down (using a 100W lamp) just to see how long they last and hopefully keeping the battery "exercised".
