A method of manufacturing a lead terminal for an accumulator by plastic deformation on a cold-working apparatus that has a shaping station ( 2 ) and at least one deformation station ( 30. 40, 50, 60, 80 ) by shaping, at the shaping station, a slug ( 7 ) that has a longitudinal extension along a longitudinal axis such as to provide base ( 9 ) and contact ( 8 ) parts for the terminal and a size commensurate with the size of the terminal end piece to be manufactured; transferring the slug ( 7 ) to the deformation station ( 30, 40. 50, 60, 80 ); carrying out a first deformation of the slug ( 7 ) for inner and outer shaping of its base part ( 9 ); and carrying out a second deformation of the slug ( 7 ) for performing at least a further inner and outer shaping of the base part ( 9 ), the deformations being performed sequentially as progressive deformation steps.
