If batteries really are used in cars, they will be, by far, the largest source of bad batteries. And it's pretty tough to just throw away a 800-lb battery. It's the same reason that old car engines are recycled, not trashed.

Right now Nissan will replace the battery in your Leaf. But they _require_ the old one since its value is built into the cost of the replacement.
