Providing the Most Cost-Effective, Reliable Power Source for Your Aircraft

Marathon initiated the development of the nickel cadmium batteries in 1948, and be­came the first company in the United States to manufacture a rechargeable, sintered plate nickel cadmium battery. The company’s technological and industry firsts over the decades have placed Marathon as a leader in the aerospace market.

With the development of the M3 Micro-Maintenance battery, Marathon Norco was able to meet and exceed the airlines growing demands of providing a more cost-effective solution while simultaneously providing product improvements such as reduced maintenance, faster recharge, and extended life.
