"Reconditioning your batteries". Have you ever heard of this? One of my friends has just found out a product which helps all old and dead batteries recondition. That is EZ Tom Ericson’s battery reconditioning technique. Surprising and exciting, right? That is my first impression when I first heard of this  product. My friend is still hesitating to buy this product and asking for my advice. To be honest, I had no knowledge of the product when I first knew it. I hope that anyone here can give me more knowledge of this product. How does it work? Is this product worth buying? Thank you
