    We just bought new smoke detectors and they take AA, I bought a 9v just out of assumption and got home and was blown away

        Eh 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.

          I thought I watched some YouTube video where they linked them and it worked. But who knows how accurate the numbers were. I guess not since you know.
