 An important early customer for Electric Storage was the Electric Launch Company, also known as Elco.In 1893, the Norwegian explorer, Fridtjof Nansen, used Tudor accumulators supplied by the AFA during the expedition to the North Pole, which began in 1893, and from which he returned safely and intact in 1896.The batteries which gave light during the long polar nights were charged by a windmill, and the dynamos which were used for recharging are exhibited in the Fram Museum in Oslo, Norway.
