   Edison's batteries were profitably made from about 1903 to 1972 by the Edison Storage Battery Company in West Orange, New Jersey. In 1972 the battery company was sold to the Exide Battery Corporation, which discontinued the product in 1975. The battery was widely used for railroad signaling, forklift, and standby power applications.

4. Magnesium battery - Wikipedia

   A magnesium–air battery has a theoretical operating voltage of 3.1 V and energy density of 6.8 kWh/kg. General Electric produced a magnesium–air battery operating in neutral NaCl solution as early as the 1960s. The magnesium–air battery is a primary cell, but has the potential to be 'refuelable' by replacement of the anode and electrolyte.

   In the United States there are codes on batteries that indicate when they were manufactured. When batteries are stored, they start losing their charge; this is due to non-current-producing chemical reactions of the electrodes with the battery acid. A battery made in October 2015 will have a numeric code of 10-5 or an alphanumeric code of K-5.
