The Raymax Zinc Carbon batteries are used extensively all over the world. They have a great price to quality ratio and are made with simple, tried-and-true technology. For low drain devices, the battery is affordable in terms of cost per hour.

An electrochemical interaction between zinc and manganese dioxide produces direct current in a zinc-carbon battery, a stem cell disposable battery. The rod cathode, which is positive in polarity and is made of carbon, provides a voltage of roughly 1.5 volts between the zinc anode, which typically serves as a battery's container, and the manganese dioxide electrode, which gives the cell its name.
