I don't think anyone mentioned this, but the inverter part of a UPS is a
switching power supply. Why add to the potential noise cloud around the
station? I have noticed lots of noise pollution from my various computer
UPSs. The solution of floating a battery across the output of the
regular 12v supply seems simpler and quieter to me.

Interesting! I was thinking along the same lines about a UPS for the
shack, but for a different reason.
Aren't today's solid-state radios susceptible to damage from transients,
much like our computers are?
I would not turn on a computer that was not first connected to a quality
UPS with surge protection.
So, maybe not so much for backup, as most UPS are designed to continue
to supply power to the computer and peripherals long enough to effect an
orderly shutdown.
We don't suffer from protracted power outages here, but rather from sags
in the line voltage. This is especially true in the summer, when
temperatures reach 100F and higher.
But, what about surge suppression for our shack equipment? Or is this a
silly question? Are we more susceptible to damage from lightening than
from dirty power?

Here is a link to the PWRgate that I believe Bruce is referring to.
This item is a compact, relatively low cost, well regarded solution
that would be appropriate for use in the scheme Bruce has suggested. A
yellow or blue top Optima, or other good AGM battery, along with a
PWRgate, wouldn't cost too much more than the UPS being considered,
but would be much more useful & versatile.
