Battery transplant, recycling to the max

While cleaning my work shop, I found a couple of DeWALT Batteries that were completely dead. They would not take a charge, and zapping them with high voltage did not work ether. Since most of my tools are DeWALT having extra batteries is helpful. So i wasn't just going to recycle them. Decided to take the surgical approach and do a transplant. I used to have a Milwaukee 18 volt drill, unfortunately it's not with us anymore. Held on to the batteries in the hopes that one day I just might buy another one. Well, never did. But now I have a new purpose for it. Green element: Using a battery to it's full potential before recycling, I figure might creates less waste, because I'm not buying a new one, just giving old one another purpose. By the way, just because you see me doing this, and it works for me, does not mean, that i said it was okay for you to do it, and if you blow your self up in the process don't come crying back to me. Take responsibilities for your own actions.
