What is the best way to restore a lead acid battery? The battery is a small 4V battery out of a flashlight.

It is amazing - the one about recovering gold from phones is even more interesting.

But I do feel bad about what it must be doing to their bodies.

You can just use distilled water + table salt solution in place of battery solution
