Has anybody watched the on-line info about the revival of old batteries? It is one of these things that totally bug me. The guys say the same thing over and over without coming to the point. After watching the thing for 5 minutes and two consecutive speakers saying the same thing again and again, I left it. What are these things all about? They don't seem to sell anything, do they? Why are they dragging on and on. Has anybody had the patience to watch the thing to the end?
