>When a Nicad battery is drained it develops an internal short circuit rendering the battery “useless”. In 1974 I developed a way to overcome this characteristic by using a variable source of Alternating Current and making a momentary contact between the AC source and the Nicad terminals. It broke the bond on virtually every Nicad we had that we thought was useless.

Good to know. We use a lot of batteries in the medical field.

>It is best to know what you are doing as this could cause an explosion!

Explosions, sweeeet.
