Zinc-carbon batteries are a type of dry cell battery commonly used in low-drain devices like remote controls and flashlights. They consist of a zinc anode, a carbon rod as the cathode, and an electrolyte paste. These batteries are known for their affordability and availability. While zinc-carbon batteries are less powerful than other types, such as alkaline batteries, they are suitable for devices that do not require high energy output. Their design makes them easy to manufacture, but they have a shorter lifespan and lower energy density compared to more advanced battery technologies.
