UPSes (and UPS batteries) do fail, sometimes in catastrophic ways. I would not design any critical system on the assumption that any particular component won't fail. High availability is about designing for failure. Sometimes there is a long time between failures, other times they occur early and often. The most annoying thing about UPSes is they fail at exactly the time they are needed most.
