On many Duracell "Original Equipent assemply" instead of "PLUS" is on it, for all this do not know: but this is the same quality / standard, only one Industrieerstausrüstung and other aftermarket. That's what happened here. So far everything ok, best 9V the world. He is 200% cheaper than in the store is of course amazing! I have stayed here several times ordered these 9V, the packaging is different each time, lately, they were sealed, but the plastic wrapping was full of holes on the contacts so that they as can loosely wrapped each other at the poles touch, which I find not so nice because there is a need for improvement.
