This is the batteries i used, 2 of this Kodak, and one of that new unopened, and one another brand i forgot, so i have this one remaining and not sure if it will work. I ordered 20 pieces of thise 4L... batteries from ebay to be used for RZ and Mamiya 7, but i doubt it may work with Mamiya 7II, RZ has no issue with battery even if doesn't last longer.
