Automobile Battery

A battery is a device in which the energy of a chemical reaction is converted into electricity. This is accomplished by immersing two metals in an electrolytic solution, where the electrolyte, a non metallic conductor, dissociates into charged components, or ions. The metals must be chosen according to their electrochemical activity, which depends on their ability to gain or lose electrons. This gain or loss causes a potential difference or voltage, between the two metals. When the metal are connected by an external circuit to a load such as light bulb, a current of electrons will flow from one metal (the anode), through the wire and the load, to the other metal (the cathode). Ion carry the current through the electrolyte solution and complete circuit.

Eveready Carbon Zinc

Eveready Carbon Zinc (Zn/MnO²)

Eveready carbon zinc batteries are marketed in two basic categories--Classic and Super Heavy Duty. The Classic category, our least expensive battery line, is most appropriate for light to moderate periodic power needs or occasional use. The Super Heavy Duty category, premium carbon zinc, performs better than the Classic category on moderate to heavy drains or continuous drains.

Two electrochemical systems are used in Eveready carbon zinc batteries--LeClanche and Zinc Chloride. Classic product is often but not always, constructed using the LeClanche system. Super Heavy Duty product is usually, but not always, constructed using the Zinc Chloride system.

For several years, Eveready Battery Company has aggressively pursued the reduction of heavy metals in all carbon zinc batteries. All of the batteries described in this data book, with the exception of a few which are noted, have no added mercury or cadmium. If further information is needed, consult your Eveready salesperson.

System Description:

Carbon Zinc: A generic term for primary dry batteries of the LeClanche or Zinc Chloride system. These batteries have an anode of zinc, a cathode of manganese dioxide, and a slightly acidic electrolyte.

LeClanche: A carbon zinc battery with a slightly acidic electrolyte consisting of ammonium chloride and zinc chloride in water.

Zinc Chloride: A carbon zinc battery with a slightly acidic electrolyte consisting mainly of zinc chloride in water.

Carbon zinc batteries provide an economical power source for devices requiring light to moderate drain because of the use of inexpensive materials and their time proven constructions. Eveready Battery Company manufactures both LeClanche and Zinc Chloride carbon zinc batteries that differ in price, capacity, and rate capability. All Eveready Battery Company carbon zinc cells are primary batteries and therefore are not designed for recharging.

The service capacity of a carbon zinc battery is not a fixed number of ampere hours because the battery functions at different efficiencies depending upon the conditions imposed upon it. The service varies with current drain, operating schedule, and cutoff voltage. The battery is also affected by the operating temperature and storage conditions.

The general characteristics of an Eveready Battery Company LeClanche battery are:

• Less expensive than alkaline or Zinc Chloride. Economical in terms of cost per hour of use on light current drains.

• The widest variety of shapes, sizes, and capacities within the primary battery system. Available in voltages ranging from 1.5 volts to 510 volts.
