The batteries I use are either the Energizer Industrial AA batteries
The only difference between the "Industrial" and the regular consumer model is: packaging
Industrial batteries are generally sold in bulk quantities and labeled "Industrial" for mainly commercial sales. Our Batteries Plus catalog showed the mah rating of the alkaline products we carried and the Industrial and Consumer versions were both rated the same for Duracell and their Procell, Energizers and its industrial, and Rayovac and its Industrial.
The mah ratings between the big three only vary around 100-200mah, which is pretty small. When people asked me which was the best, I told them, buy whichever is on sale. 30 cents a AA is a pretty good deal. 20 cents is a steal. 50-75 cents is about average pricing. Cost to stores was generally between 15 and 20 cents a battery for bulk packaging.
