The model M3 -28-1 (P/N 33206-001) is a 19-cell Micro-Maintenance battery, with a nominal voltage of 24V, and a nominal capacity of 28Ah, at a weight of only 55 lbs. (max). The M3-28-1 will provide an Imp (15-second discharge @ maximum power transfer) of 1000 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 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.
