Its a good idea. I have 2 UPS'es and I tested them but was only able to run a single powerhead for about 1-2 hours. In my opinion, that's not very cost effective. I think I was using APC Smart-UPS 500 or something. I would have to check. For more money, I could get the higher end models to get maybe 8 hours but that's pretty expensive.
The cheapest way to aerate a tank I think is a battery operated air pump like this:

I bought one last week but haven't tested it yet. They do look cheaply made though but I guess it should be able to run several days or maybe weeks on battery power. If the power outage lasts more than a day or 2, this isn't going to do much good if the temperature is extremely cold or hot of course.
