The electrolyte in an alkaline battery is a gel composed of potassium hydroxide and zinc powder–it’s like the buckshot in the hammer. As the battery becomes depleted, this gel-like material becomes more dense and doesn’t shift around, thus it can’t dampen the bounce when you drop the battery.
Steel is dense but it still bounces. Certain rubbers are light but don't bounce and others are heavy and do bounce. Bounce-a-bility is not dependent on density.

As the battery drains, a reaction happens (of which I don't remember) that turns some material into another. I think it's an oxidation reaction. In any case, this material is a relatively bouncy substance compared to the unoxidized material. As a matter of fact, this oxidized material is the same stuff used in a certain bouncy ball; I think it's the innards of a golf ball?
It should work for most conventional batteries like the AA, AAA, and D batteries you find in Walmart.
But rechargeable ones and specialized ones won't work because they work differently in compare to the average ones.
