Method for managing a battery comprising several accumulators that can be linked in series or in parallel, comprising a charging or discharging phase during which the accumulators are disposed in series, characterized in that it thereafter comprises a balancing phase comprising the placing of the accumulators in parallel, during which an electrical quantity Gmin representing the balancing of the accumulator that has attained the maximum voltage during the charging phase or minimum voltage during the discharging phase is measured or estimated, and during which an electrical quantity Gi representing the balancing of another accumulator i of the battery is also measured or estimated, and in that the state of health SOHi of this other accumulator i is computed on the basis of the two electrical quantities Gmin and Gi and on the basis of the knowledge of the performance of the accumulator i at the start of life.
