I think I may have an Eaton, or Compupower, at home. I think most of the
consumer-grade ones are similar.

The SmartUPS are... but then, overwhelmingly, mine are rackmount. I have
mentioned here, before, though, that at least with the SmartUPS, you can
easily, and far less expensively, buy replacement batteries, but they
*MUST* be HR (high rate) batteries; anything else, and the SmartUPS don't
believe they've been replaced correctly.

Isn't even a price difference - it's just for a different market, and most
of the vendors, nor the OEM's reps I've spoken to, know *anything* about
