Rechargeable Batteries

I’ve used rechargeable batteries for many years, mostly nickel-cadmium batteries, also known as nicads, which are ideal for infrequently used items such as radios or flashlights. They can be stored safely and they don’t lose their charge over time. Even though nickel-cadmium batteries can last far longer than most people think, they do eventually wear out and need to be replaced.

When I recently tried to buy some replacement nickel-cadmium batteries, I was surprised that I couldn’t find them anywhere. Nickel-cadmium batteries must have gone out of favor while I wasn’t paying attention. Environmental concerns may have played a role because cadmium is a heavy metal and difficult to dispose of safely.
