Extrcted from Wikipaedia: Eveready Battery Company, Inc. is an American manufacturer of battery brands. Eveready and Energizer, owned by Energizer Holdings. On January 10, 1899, American Electrical Novelty and Manufacturing Company obtained U.S. Patent No. 617,592 (filed 12 March 1898) from David Misell, an inventor. This "electric device" designed by Misell was powered by "D" batteries laid front-to-back in a paper tube with the light bulb and a rough brass reflector at the end.[3] Misell, the inventor of the tubular hand-held "electric device" (flashlight), assigned his invention over to the American Electrical Novelty and Manufacturing Company owned by Conrad Hubert. In 1905, Hubert changed the name again to The American Ever Ready Company, selling flashlights and batteries under the trademark Ever Ready. In 1906 the British Ever Ready Electrical Company was formed for export of batteries; it became independent in 1914. In 1914, The American Ever Ready Company became part of National Carbon Company. Hubert stayed on as the president. The trademark was shortened to Eveready. In 1917, National Carbon Company merged with Union Carbide to form The Union Carbide and Carbon Company. From 1917 until 1921, Eveready used the trademark "DAYLO" for their flashlights and on their batteries. In 1957, employees Lewis Urry, Paul Marsal and Karl Kordesch invented a long-lasting alkaline battery using a zinc/manganese dioxide chemistry while working for Union Carbide's Cleveland plant.[5][6] The company did not aggressively market the invention, however, and instead continued to market the old Zinc-carbon battery. As a result, the company lost significant market share to Duracell. Prior to March 1, 1980, the company's alkaline battery had been called the Eveready Alkaline Battery (19591968), Eveready Alkaline Energizer (19681974) and Eveready Alkaline Power Cell (1974February 29, 1980). On March 1, 1980, it was rebadged under its current name, Energizer. In 1986, Union Carbide sold its Battery Products Division to Ralston Purina Company for $US1.4 billion, becoming the Eveready Battery Company, Inc., a wholly owned subsidiary. At that time, the Eveready and Energizer batteries held 52 percent market share. The company under Ralston lost market share to rival Duracell. In 1992, it bought the British Ever Ready Electrical Company (manufacturer of Gold Seal and Silver Seal batteries) from Hanson Trust,[8] bringing its former subsidiary back under common ownership. In 1999, Eveready sold its rechargeable battery division, although it still markets them for retail sale. In 2000, Ralston spun off Eveready, and it was listed on the New York Stock Exchange as a holding company, Energizer Holdings, Inc., with Eveready Battery Company, Inc continuing as its most important daughter company. The company's current US production facilities for batteries and battery parts are located in Asheboro, North Carolina; Bennington, Vermont; Maryville, Missouri; St. Albans, Vermont; and Marietta, Ohio; with a technology center for research located in Westlake, Ohio.[9] There are also numerous production facilities outside the US.
