Restoration of old car batteries?
I keep reading on the web how lead/acid vehicle batteries can be restored with a solution of Epsom salts. But the posters mostly say to replace the acid solution with an Epsom salts solution. I can believe them up to that point and on through the charging with the Epsom salts but don't you then have to drain the salts solution and replace it with acid and water before charging it and putting it back into service? You can't use it with no acid can you?
Orion, you should Google "Epsom salts" or "battery restoration" if you really don't know where the idea comes from. The idea is the magnesium sulfate, commonly sold as Epsom Salts, would remove the sulphation in the dead battery enabling the reactivation of the battery. The web is full of people telling how to do it and also of people selling kits to accomplish the feat. I am asking, since most of those people seem to know more about donning rubber gloves than anything else, if it would not entail the removal of the magnesium sulfate solution after some time and replacing the H2SO4 solution and charging the battery. If it would now take a charge of course. Try it, you may like it.
