A well-known electronics store has been selling a very simple lead-acid battery activator for many years. Although I can't prove it, my lead-acid batteries do seem to last longer since I started using the activator. The principle behind this circuit is very simple. The battery is loaded with a current of about 100 A for a period of 100 µs, which is repeated every 30 seconds. But my circuit is capable of more, which is discussed at length in article from 2017.
