This folder contains correspondence and other documents relating to the commercial and technical development of Edison's alkaline storage battery. Included are numerous items in Edison's hand, including a list entitled "Uses for Edison Battery"; its typed draft, prepared by Miller Reese Hutchison, bears marginalia by Edison. Also included are notes, draft correspondence, and interoffice communications relating to experiments, cell tests, the procurement of equipment and supplies, advertising, and sales and administrative practices. Other items pertain to commercial development in foreign markets, including a report concerning Russia by foreign representative Maurice E. Fox. Some of the letters discuss the use of batteries in delivery wagons, electric bicycles, and telephones. There is also correspondence with the Hooker Electrochemical Co., the National Hydro-Carbon Co., and the Niagara Alkali Co. relating to Edison's investigation of a lower-cost substitute for German potash. In addition, there are numerous unsolicited requests for information about the battery, some with marginal notes by Edison. A sample of these letters has been selected. Among the correspondents are Edison associates William G. Bee, Frank L. Dyer, Ignacy Goldstein, and Walter E. Holland. Other correspondents include electrical engineers Henry M. Byllesby of Chicago and W. Hibbert of the London Polytechnic; Arthur I. Clymer, an investor in the Edison Storage Battery Co.; and Theodore N. Vail, president of the American Bell Telephone Co.

Approximately 80 percent of the documents have been selected. The items not selected consist of unsolicited correspondence, a translated copy of "Alkaline Iron Nickel Accumulator," and an address delivered by J. A. Montpellier at the International Congress of Electrical Applications in Turin, Italy.
