Shelf Life
Alkaline cells have long shelf storage life. After one year of storage
at room temperature, cells will provide 93 to 96 percent of initial
capacity. When stored for five years at 70°F (21°C), service
of about 85 percent is still attainable. Storage at high temperatures
and high humidity will accelerate degradation of chemical cells. At
low temperature storage, the chemical activity is retarded and capacity
is not greatly affected. Recommended storage conditions are 50°F
(10°C) to 77°F (25°C) with no more than 65 percent
relative humidity.
The following figure compares various DURACELL zinc anode systems
and the effect of temperature on capacity retention.
