The one in my last apartment was electric, but I believe still had a backup battery. And still chirps like the devil if that goes out, but you can't even just remove it, because then it'll chirp at you for not having a backup battery in place. And there's no way that I know to turn that chirp off. See how that might be annoying in the middle of the night with high ceilings in the first place, and no replacement battery available?
