M3-1760L-1 MicroMaintenance Battery

The Marathon Micro-Maintenance M3 battery is a greatly improved nickel-cadmium (Ni-Cd) battery that features:
• Significantly Increased Maintenance Intervals
• Very Low Water Consumption
• Excellent Capacity Retention During Extended Cycling
• Same Physical Size As Standard Ni-Cd
• Lower Weight Than Standard Ni-Cd For A Given Capacity
• Same Or Better Power Than The Standard Ni-Cd

The battery incorporates a state-of-the-art negative pasted electrode that provides high volumetric and gravimetric energy density. This, along with the standard sintered positive electrode, provides a high capacity battery with excellent power. Other characteristics of the battery include our standard, internally threaded butt terminals, long life separators, nylon cell cases and covers. The design of the battery increases the electrolyte reserve to more than two times the standard Ni-Cd battery. The M3 battery was designed to increase the battery maintenance interval. This design has reduced electrolyte consumption, coupled with an increased electrolyte reserve, results in a increased maintenance interval of two to six times.


  • The M3-1760L-1 is currently PMA’d for the following applications: Bombardier Regional Jet Series: 100, 200, 440, 700, 701, and 900.
  • The M3-1700L is designed as a low-maintenance replacement for Saft 1756-1 battery.
