Marathon Power Technologies Company

MarathonNorco Aerospace, Power Distribution


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.

Technological Benefits Include:

  • Significantly Increased Maintenance Intervals (Two to Six Times)
  • Very Low Water Consumption
  • Double the Electrolyte Reserve in Comparison to Standard Ni-Cd
  • capacity Retention During Extended Cycling
  • Better Capacity than Standard Ni-Cd
  • or Better Power than Standard Ni-Cd
  • Same Physical Size and Weight as Standard Ni-Cd
