This folder contains correspondence and other documents relating to commercial and technical development of Edison's alkaline storage battery and its use in electric vehicles. Most of the letters are by William C. Anderson, president of the Anderson Electric Car Co. and manufacturer of the Detroit Electric automobile. Some of the items concern Edison's competitors, including the Electric Storage Battery Co. of Philadelphia, manufacturer of the Ironclad-Exide battery. Also included are remarks by Edison regarding the performance, capacity, and efficiency of batteries, rectifiers, and vehicles. A newspaper clipping enclosed in one of Anderson's letters discusses the divorce of Frank J. Kellogg, a childhood friend of Edison.
