Have any of you heard of this. Not sure how I found it, but I saw a video about reconditioning old car batteries with an epsom salt solution. I have an old car battery that will still show 12 volts, but is too dead to run anything. I did not go and core it, and now have lost the receipt. Figure what the heck. I'll give it a shot. I use to have a pair or deep cycle batteries that I used for welding and general battery backup. I would take one 4 wheelin and such. All the text and videos I have read are inconstant with the process. Some simple top off with the epsom salt solution. Some drain the acid and replace with solution. Some rinse the cells with water then fill. And finally one old bat rinsed out the cells with a baking soda solution then filled with the epsom salt solution. Do you have some first hand experience with this. What did you do. What do you recommend. I know some of you will say a dead battery is done. Buy a new one. But I already have a new one. I just want another working car battery. Thoughts?
