Many dead zinc size 10 batteries in weird situation

Exactly. What folks may not realize is the positive “terminal” of these batteries is not just the surface with the sticker/tab on it, but extends along the curved sides, separated from the negative “terminal” only by a narrow gap. Bridge that gap with anything metal (including another battery) and it’ll discharge.
