Zinc-Carbon batteries are a type of primary battery that uses zinc as the anode and carbon as the cathode. They are commonly used in low-drain devices like remote controls and flashlights. These batteries are known for their affordability and availability, making them a popular choice for everyday use. The chemical reaction in Zinc-Carbon batteries involves the oxidation of zinc and the reduction of manganese dioxide. While they have a lower energy density compared to other battery types, such as alkaline batteries, they are still effective for applications that do not require high power output.
