       Introduction
         Duracell pioneered the alkaline-manganese dioxide electrochemical system nearly 40 years ago. In the
1960-1970 decade, this battery system rapidly became the popular choice of designers in the ever-widening
field of consumer electronics. The product information and test data included in this technical bulletin repre-
sent Duracells newest alkaline battery products.
         The zinc/potassium hydroxide/manganese dioxide cells, commonly called alkaline or alkaline-manganese
dioxide cells, have a higher energy output than zinc-carbon (Leclanche) cells. Other significant advantages are
longer shelf life, better leakage resistance, and superior low temperature performance. In comparison to the
zinc-carbon cell, the alkaline cell delivers up to ten times the ampere-hour capacity at high and continuous
drain conditions, with its performance at low temperatures also being superior to other conventional aqueous
electrolyte primary cells. Its more effective, secure seal provides excellent resistance to leakage and corrosion.
         The use of an alkaline electrolyte, electrolytically prepared manganese dioxide, and a more reactive
zinc powder contribute to a higher initial cost than zinc-carbon cells. However, due to the longer service life,
the alkaline cell is actually more cost-effective based upon cost-per-hour usage, particularly with high drains
and continuous discharge. The high-grade, energy-rich materials composing the anode and cathode, in conjunc-
tion with the more conductive alkaline electrolyte, produce more energy than could be stored in standard zinc-
carbon cell sizes
           General Characteristics
         The general characteristics listed below are a summary of the significant benefits of the alkaline man-
ganese dioxide system. Each of the benefits is explained in greater detail subsequently in Section 5. This sum-
mary provides the designer with general guidelines for evaluating the alkaline-manganese dioxide system for a
particular application.
Benefits include:
   Up to ten times the service life of regular zinc-car-            Cost-effective on a cost-per-hour-of-service basis.
