Okay, this isn't a product you can buy, but when you ARE shopping, you should look out for these collection boxes. Bring your old cell phones and old rechargeable batteries (from cordless products like cordless phones and power tools) and drop them in the box for recycling. It's free and they'll get recycled into new metal products. You can find these boxes in stores like Radio Shack, Best Buy, Sony Style and Lowe's.
