Sign up over on candlepowerforums.com and see if anyone would be willing to pay shipping to take them off of your hands.
If you don't want to do that, Home Depot usually has a box up by the entrance where you can drop them off.
Why would someone pay to have dead batteries?
I've taken apart several dead laptop packs that has 2-3 dead cells in it, and the rest (as many as 6-7) were still good. New, they sell for upwards of $5 per cell.
