A method for managing the electrical energy passing through a metal-air battery comprising a cell and the associated cell comprising a negative electrode, a first positive electrode referred to as the air electrode, and a second positive electrode referred to as the power electrode. The cell further comprises a third positive electrode. In a first charging phase, a charging voltage is applied to the cell, this voltage causing current to travel between the negative electrode and the second positive electrode, the first and third positive electrodes being electrically inactive. In a second charging phase, the charging voltage causes current to travel between the negative electrode and said third positive electrode, the first and second positive electrode being electrically inactive.
