I just looked at mine, and there is a kind of lever that the battery depresses. If the battery weren't there, the lever would be open. I don't know if that has any effect on operation.

Personally, I'm with you: I like using AC adapters for various household thingies. Maybe a little wasteful, but saves a heap of labor.


P.S. It does occur to me that a power failure might not be an unexpected event accompanying a fire.
