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-

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.
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
