    Here’s one.

    Works best with alkaline batteries, don’t try it with lithium.

    The reason is that alkaline batteries work off a chemical process, and as they are used they fill with pressurized gas. The difference in pressure causes the bounciness.

        Yeah, unfortunately this tip is losing relevance as the technology is being replaced.

        As an aside, I remember about twenty years ago or so you could buy disposable AA/AAA batteries that had a gauge telling you how full they were. They worked by squeezing the battery, which I believe created a circuit with your hand, which was enough to power a cheap LCD strip on the battery.

        It never worked very well, the batteries basically said they were more full if you squeezed them harder. Back then it was easier and quicker to give them the drop test.

          They also had trouble fitting inside some tight battery compartments. Many a finger was squished trying to make the last one fit 😪
