ADVANTAGES AND APPLICATIONS

The DURACELL zinc/potassium hydroxide/manganese dioxide battery system, commonly referred to as alkaline or Alkaline Manganese Dioxide, is now recognized as the premium primary zinc anode battery system. It has been selected for consumer, industrial and military applications where an economical and reliable battery is required.

Its major advantages (compared to the zinc-carbon battery system) are a high energy density; the ability to operate continuously at relatively high discharge rates over a wide temperature range (due to its lower internal resistance); and a shelf life in excess of four years. The cost of the alkaline battery, on a service life basis, is lowest in medium to high drain applications.

Unlike other websites, we display the prices per consumer pack (NOT per battery) regardless of the unit of batteries it holds to make sure that you will not get a surprise when you check out.
