ZEUS alkaline batteries are manufactured in various sizes—AA, AAA, C, D, and 9 volt—to suit their application and needs. They are free of mercury and cadmium, which make them non-toxic and environmentally friendly. Alkaline batteries are a smart choice because they last a long time, perform well at high and low temperatures, and have a long storage life. They can be stored at room temperature for two years and still retain 90 percent of their original capacities. ZEUS alkaline batteries are high performance—designed with high current and large capacity.
