While it's bad to use those silver batteries (carbon-zinc) in a smoke
detector, a fresh one that really was fresh (shelf life is terrible,
especially at high temperatures) should be able to sound the alarm
because I've seen them do so, and that was with very old detectors
with  mechanical buzzers that drew 150 milliamps.  Today's detectors
instead usually use piezoelectric whistles that draw far less current.
