In June when we came into Cozumel and went thru security they inquired about the batteries in my checked bags (in their original packaging) oops
but when I explained that they were for dive lights, we went thru with no problem. I had extra batteries for my camera too but had no issues with having those in my carryon on arrival or departure. I understand batteries are expensive in Mexico. Might be better to give them to your boat crew or DM at the end of the trip rather than have them thrown in a bin at the airport.
