EVEREADY 1015-SW4 AA Zinc carbon batteries were the first commercial dry cell batteries. The ability of zinc-carbon batteries to function in any orientation helped in the development of various portable devices like flashlights and radios. These batteries have a long shelf-life which allows them to retain a charge for lengthy durations even when left unused. Catering to a wide range of needs, Eveready’s zinc carbon batteries come in a range of sizes from ‘AA’ to ‘D’.
