Does anyone have any experience with a battery rebuilder called Voltman in Mansfield OH. He has decent web site ?. He has a U-tube demonstration on it which looks pretty reassuring. He'll rebuild a Dewalt 12V NICAD battery pack for $45. You pay the freight charge to OH, he returns it to you on his dime. Two to four week turn around. He says their rebuilds are better than new.
