Abstract: In one embodiment, a method can be used for measuring an effective capacity of a battery. A first measurement is performed during a phenomenon of relaxation of the battery. The first measurement measures a first voltage delivered by the in-use battery from a duration. The duration is the difference between a first initial time and a second time that is defined as the time when a first line reaches a second voltage delivered by the battery when the battery is relaxed, the first line being tangent to the origin of a curve corresponding to the evolution over time of a voltage delivered by the battery during the phenomenon of relaxation.
