The invention relates to a method for managing the electric power passing through a cell (100) of a metal-air battery (400) and the associated cell. The cell comprises a negative electrode (10) connected to a positive terminal (101) of the battery, two positive electrodes (20; 30) and a switching means (70). Furthermore, the switching means is maintained in an arrangement connecting the positive terminal to the first positive electrode when an electric power to pass through the battery corresponds to a first power range, and in an arrangement connecting the positive terminal to the second positive electrode when an electric power to pass through the battery corresponds to a second power range, the second power range being associated with greater electric powers than electric powers of the first range.
