Zinc (Heavy Duty)
Zinc carbon batteries are dry cell batteries that deliver a potential of 1.5 volts. Although carbon is an important element of the battery's construction, it takes no part in the electrochemical reaction. The cell could more properly be called a "zinc manganese" cell.
Zinc carbon batteries were the first commercial dry batteries, developed from the technology of the wet Leclanché cell, and made flashlights and other portable devices possible because the battery can function in any orientation. They are still useful in low drain or intermittent use devices such as remote controls, flashlights, clocks or transistor radios. Zinc carbon dry cells are single-use primary cells since they are not intended to be recharged.
Zinc (Heavy Duty) batteries use a "Newer Method", Zinc-Chloride, which offers 2 to 3 times the capacity of their former capacity design, Leclanché batteries. They also have better performance at lower temperatures and are less prone to leaking. Heavy Duty in the older times isn't the same as now. They still have great use today and are in demand. There are modern batteries in the marketplace that are more powerful. Some brands have created Extra Heavy Duty and Super Heavy Duty batteries that hold higher power capacities to accommodate high-end usage.
Zinc (Heavy Duty) batteries are highly used in Clocks, Flashlights, Garage Door Openers, Remote Controls, Boom Boxes, Calculators as well as in other High Drain Devices.
