Why A Dead Alkaline Battery Bounces!

This test works equally well for AA, AAA, C, D and 9 Volt alkaline batteries. It is our understanding that the following chemical reactions occur and helps to explain our observations. A non-rechargeable alkaline battery begins life using zinc powder mixed into a gel containing a potassium hydroxide electrolyte separated from a paste of manganese dioxide powder mixed with carbon powder using a porous membrane. To minimize hydrogen outgassing an extra measure of manganese dioxide is added. As the battery d
