The iconic Duracell "coppertop" battery is Made in USA.
Duracell originated via the partnership of scientist Samuel Ruben and businessman Philip Rogers Mallory, who met during the 1920s. The P.R. Mallory Company of Burlington, MA produced mercury batteries for military equipment. During the 1950s, Kodak introduced cameras with a flash: the design required a new cell size, and size AAA was developed.
In 1964, the term "Duracell" was introduced as a brand-- a "durable cell."
