How much Ni is used in a AA size NiCad battery???? In the battery recycling Wikipedia page, it has a table which shows that a NiCad is 22% Ni, and NiMH is 35% (I assume by mass?). What's an AA weigh, a few tens of grams? 100g?

Assuming the Ni or Pd in a cold fusion cell does not transmute, you can recycle nearly all of it. It is all sealed up inside the cell, in one place, undisturbed. The used cell will be collected by an authorized dealer and sent back to a remanufacturing facility. This is unlike the metals in many other manufactured items. For example, much of Pd used in a catalytic converter ends up being blown out of the converter by the stream of hot gas from the engine. Much of precious metals in consumer goods is lost because it can be expensive to recover, and because people do not recycle properly. One source says: "A tonne of ore from a gold mine produces just 5 grams of gold on average, whereas a tonne of discarded mobile phones can yield 150 grams . . ." Automobile lead-acid batteries are recycled effectively because they are usually replaced by professional auto repair garages. They all end up in one location. If you have large lead-acid batteries from a wheelchair, a boat or something like that, any garage will take it. They have piles of them in back, waiting to be recycled. - Jed
