I left a penlight flashlight with 2 Energizer cells in it turned on for a month. By then one cell was reading +1v and the other -1v. Even a month later the latter was still at -.4v. This was verified by an EE type in this dept. The polarity was really reversed. My guess was that one cell was smaller inside or had been used a little more, somehow. Then the bigger cell forced some chemical reactions that don't normally occur to occur. Can anyone add details? Thanks. -- Wm.
