Duracell Coppertop 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. Alkaline or Alkaline Manganese Dioxide cells, have many advantages over zinc-carbon cells including higher energy output.

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.
