This could provide battery power to smoke detectors, carbon monoxide
detectors, HVAC thermostat, security system, clocks, digital thermometers,
computer UPS, phone answering machine, etc.

Then only ONE battery to worry about...

Hmm, I generally use batteries for *PORTABLE* devices. The stuff that
sits in one place is all AC operated. I think your idea needs work.


His idea may need work, but I still have plenty non portable things with
battery power or battery backup. Both thermostats have AA cells. My light
timer and clock radio use batteries for backup. Telephone memory has 4
cells, a caller ID unit has a 9V. Some of those items have plug in
adapters, some don't. I have one smoke/co detector that is battery
operated, the others are had wired.
