Well this is turning out to be more difficult than i expected. All 4 of my buyers for nicad and alc batteries closed.
I made it a habit of not sending less than 100 pounds of a class of dry cells in a shipment and I've been testing ebay for selling "dead" batteries of late.
http://www.watchbatterybuyers.com buys silver oxide and some of more heavy gold plate stuff boardsort doesn't want. Been around a while... I've used them and I trust them.
For the moment I'm stuck on not being Able to suggest anything else.
I have enough of each class on hand if anyone finds a buyer they want info on post the link and I'll send a test shipment and keep updates along the way.
Almost all large volume steel yards will take batteries of any type but tend to be at the lower end of the price range. Usually shred for canister dry cells. Eg aa and aaa and D.
