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.
