Here’s a simple trick to test to see if an alkaline battery is dead. When you bounce a dead (or bad) alkaline battery on a solid surface it will bounce, while a good battery will fall over and not bounce.
One theory as to why this happens is that there is an internal chemical change that takes place as a battery loses its charge; in a good battery there is a gel-like substance that creates a downward force that stops it from bouncing, while in a bad battery this substance has become solid. However, the jury is out among physicists and engineers as to whether this trick really is an accurate way to measure a battery’s life.
Still, it sure looks like a good short cut to quickly determine if a battery is running out of its charge. I’m going to test it out for myself.
