Ditto to this. I work with some smaller retail stores... I used to recommend UPS's on the POS computers, but after discovering a model of Belkin entry level UPS's that would cease completely if the battery got too old... we stopped using them. Changing the battery on a scheduled basis is impractical, having remote staff successfully swap a UPS would cause more problems than the UPS's would save (most power outages don't break anything if you have write-back caches disabled).
