Hard to believe the longevity is really that bad!

In a UPS that's used constantly in an area that has few power outages (an
average on the order of a few minutes a month or less), the batteries will
last 3 to 5 years or so, and that's about all you will get.



I've gotten close to 7 years out of the batteries that are currently in my
UPS, but it's possible to kill a SLA battery in a day or two under the right
conditions, only takes once of discharging it too deeply and it's shot.
