I rebuild tool batteries, the type that go in cordless drills and others. I also have a lot of odd cells that I have little use for. rechargeable batteries are just like normal batteries as far as sizes go. so if you have a rechargeable cordless phone or other device let me know. If its a battery that will just sit here and go bad You can have them. If its the sub C`s I use in tools I will give them to you for what I pay for them. Let me know what you need and I will help if I can. <S> Probably better off to message me here because I probably wont check back here much.
