Ambient temps have a huge effect on UPS battery life. Temps here are purposely
above average, between 76F (winter) and 82F (summer), saving much electricity in
cooling season, which here in Florida is long, among other reasons. Before I
moved, I had 7 UPSes online at all times due to unconscionable frequency and
length of power outages from the monopoly power provider. Since moving I'm down to
4. It was uncommon for replacement batteries to last more than 30 months, and
common that they lasted less than 24 to as little as 18 or 20. OEM batteries
usually managed up to 60. Those with plastic instead of metal cases have the
advantage that swollen old batteries can usually be extracted successfully, while
metal could necessitate such heroics as drill and saw to extricate. My favorite
brands are Tripp-Lite and Eaton.
