The company started in 1842 as the White Lead Company in Cincinnati, Ohio; it later became Eagle White Lead Works in the 1850s. A merger with the Picher Lead Company of Joplin, Missouri, occurred in 1906, becoming Eagle-Picher Lead, which evolved into Eagle-Picher Industries, Inc., and finally EaglePicher Technologies.

EaglePicher Technologies’ history as a battery manufacturer dates back to 1922. The company became a battery supplier to the U.S. Government in the 1940s and was supplying silver-zinc batteries for missiles and rockets in the 1950s. The company’s longtime heritage as an industry leader in battery production has resulted in the diverse line of products that exists today. In recent years, EaglePicher has strategically broadened its portfolio and technical expertise with the acquisitions of BlueStar (in Vancouver, British Columbia, in 2000), Yardney Technical Products (East Greenwich, Rhode Island, in 2014) and Lithiumstart (Burlingame, California, in 2017).
