Date Oct. 3, 1991.Apparatus and process for sorting used batteries and accumulators on the basis of their chemical constitution based on the analysis of the inductive effect produced by the substances which are contained in the battery or accumulator, and whose ferromagnetic properties differ according to their chemical constitution. The measurement process in which the apparatus is used is based on the consecutive application to the excitation circuit of at least two different voltage amplitudes at the same frequency or two different frequencies at the same voltage amplitude.
