Edison established Edison Storage Battery Company in New Jersey in 1901, to develop, manufacture, and sell Thomas Edison’s alkaline storage battery. Edison spent a lot of time and effort in developing a storage battery that he intended for use in electric automobiles. It took him a decade to develop a commercially viable iron-nickel battery. The battery found an extensive market for his battery in a variety of industrial uses. It became the most successful product of his later life.


The battery company was sold to the Exide Battery Corporation in 1972.
