Well, if there were a refueling station on every corner, #1 would be entirely irrelevant. It could last one charge, who cares? Of course, if there's a refueling station on every corner, #2 is already answered as well. So the real question boils down to how does an owner recycle it.

And the answer is...he/she does not. In question #1 and #2 we've established there's a refueling station on every corner where one may charge/exchange batteries. So what happens to spent batteries should pretty much answer itself.
