This strikes me as bad science.
A lead-acid battery is a fairly simple device. If all he did was run it
dead, then there was nothing really wrong with it to begin with. A
totally dead battery has all its lead and sulfuric acid tied up as lead
sulfate in the plates, and the electrolyte is essentially just water.
Water is almost an insulator; so you can't draw any more current. So
it's "dead".
Almost anything you add to the water makes it more conductive. This
conductivity will let you squeeze a tiny bit more power out of the
battery. It only takes a second or two of power to start a car; the
amphours are negligible. So this is an old con artist trick to "restore"
a dead battery.
