Depending on how you use batteries, this can be an extremely useful test that doesn't require any additional tools.

I'm generally not in the habit of using a battery a little bit, then removing it from whatever device and putting it back into storage. I put batteries in things and use them until they don't have enough charge to power those things. Sometimes "dead" in a high drain device (digital camera, shaver) can still provide enough juice to power a low-drain device (clock), but the majority of the time I use them until they are ready to be thrown away.

When you've got 8 batteries in a pile, 4 that you know are brand new and 4 that you just took out of some device that has exhausted their charge, the bounce technique works extremely well for figuring out which is which if you weren't paying attention and got them mixed up.
