Discharged AA cells bounce, fully charged cells don't. If you ever need to sort your Boebot batteries on a desert island without a voltmeter.

Don't try dropping your car battery, now.

    That was just for Alkaline but I wonder if it works for other kinds and something big like a 9V.

    Sounds like a good project for you and the girls. ;)
