check around your scrap yards, and some battery places, ie batteries plus stores or auto zone etc etc...
The price of lead is going through the roof because Americans are too ignorant to realize that China is buying out this country one battery at a time, and any other item that can be re used.
For a standard car battery, you should see at least 2 to 3 bucks,... im getting 6 per core for a standard battery, less for smaller, more for bigger etc.
