9 0 Replythey have, although some do take AA or AAA batteries but its very uncommon. some especially carbon monixide dectectors have internal batteries that require replacement.

8 1 Reply9v are just two AAs wrapped together. So not surprised.
1 4 ReplyEh not quite. AA are 1.5v so two would only be 3v.
You might be thinking of the big 6v lantern batteries. They're usually 4 x 1.5v cells together.

Get the ones with the built in 10 year battery. Smoke and CO2 combo.
4 0 ReplyUnrelated but a few days ago I found out you're not supposed to stick two 9v's together when I burnt the shit outta my fingertips :3
