M3X-54-1 54Ah MicroMaintenance Battery

The model M3 X-54-1 (P/N 33183-001) is a 19-cell Micro-Maintenance battery, with a nominal voltage of 24V, and a nominal capacity of 54Ah, at a weight of only 96 lbs. (max). The M3 X-51-1 will provide an Imp (15-second discharge @ maximum power transfer) of 1400 amps at room temperature.  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 M3-2X-54-1 is currently PMA’d for the following applications: Boeing Aircraft: 737-600, 737-700, 737-800, 737-900, 747-400, 767-200
  • The M3-2X-54-1 is designed as a low-maintenance replacement for our 46Ah TSP-46-1 batteries.
