Any UPS will have batteries, probably sealed lead-acid for a small UPS.
That is likely to negate "worry free for years at a time", especially
if wall-mounted in an unconditioned demarc/MPOE closet as opposed to a
temperature-controlled data center.
At a minimum, plan on an annual visit to do routine maintenance and load
test the batteries. You'll be lucky to get more than three years of
service out of them.
A typical Chatsworth, etc. 19-inch rack shelf available in various
depths can be flipped around and screwed to a wall to support many of
the stand-alone UPSes.
