Why is it that when the backup battery in the smoke alarm dies, the alarm starts beeping in the middle of the night? Days are actually much longer - so why can't the battery fail around noon when no one is sleeping?
It has a built in timer to ONLY go off in the middle of the night. See what you learn by being on this forum ?Why is it that when the backup battery in the smoke alarm dies, the alarm starts beeping in the middle of the night?

You were close on "Murphy's Law", but this is more a case of O'Briens Law! (O"Briens Law states: "Murphy was an optimist.")Murphy's Law!!!!!
