American company

The Edison Storage Battery Company manufactured a type of nickel–iron battery developed by Thomas Edison from 1903 to 1932. Dissatisfied with the heavy lead-acid battery, Edison developed a type of nickel–iron battery (invented by Waldemar Jungner) that was about 40% lighter for the same amount of energy stored and, he claimed, could be recharged twice as fast. He filed the first of numerous battery patents, for "Reversible Galvanic Cells or so-called Storage Batteries", on November 20, 1900, which was granted on January 12, 1901.² Wikipedia text CC BY-SA 4.0
