    Failing to an alarm on state is preferred to an alarm off state. So at least no fire can sneak up on you. I think they sell ones now that are 10-year sealed battery with a 10-year warranty.

      My building has these and 2 of them failed in the first year. Can’t replace the battery so had to replace the whole thing.
