Duracell® The Duracell® brand has its origins in the partnership of a scientist and a businessman who joined forces in the 1920s to produce mercury batteries for military equipment; the company continued to produce various mercury batteries for decades. With Kodak’s launch of cameras with a flash in the 1950s, the AAA battery was developed and the market for batteries designed specifically for consumer use expanded rapidly. Introduced in 1964, the Duracell® brand name was inspired by the concept of a “durable cell” battery. Today the company is part of the Berkshire Hathaway family of brands. Count on the coppertop for reliability in even the most extreme conditions; the batteries may be used to power toys, juvenile products, cameras, flashlights, clocks, smoke alarms, portable radios, remote controls, safety gear and more. Products include AA batteries, AAA batteries, D batteries, 9V batteries and C batteries.
