#12Would a fully discharged rechargeable battery be safe?

#14But I know that this is not actually a solution to the right problem.
Your question has that same "smell". You need to find a way to discourage this behavior, not a workaround for it.

#15I wonder if your child can taste that subtle electric effect from the battery (ever lick a 9v?)

#16But I don't think you want to train your child that it's ok to chew batteries, the moment you don't look he'll turn to the real stuff with no distinction.
Ours is leaking and chewing everything he finds, including bus railings and the likes. A year ago we started giving him those necklaces with rubber pieces that we tell him are ok to chew. That didn't fix the issue entirely, but noticeably improved things, and now he's asking for these every morning.

#17This is behaviour you need to stop, not encourage!
Frankly, the child's autism has no bearing on the matter. You would not encourage any young child to play with empty packets of drugs or dangerous machinery (even if you have made it safe).
Coat the batteries with a bittering agent. Problem solved.

#18Would applying a bitterant to both fake and real AA batteries help? I don’t have experience working with people on the autistic spectrum but seems like the first priority would be to strongly discourage a habit that could seriously poison / burn the child’s stomach?

#20Batteries dont typically have exposed copper, but if thats the route you want to go just buy some 1/2 inch copper rod off ebay, its like $12 for 6 inches. Super soft metal, you can work it by hand with a hacksaw and file/sander. I wonder if your child can taste that subtle electric effect from the battery (ever lick a 9v?)
