An electrical battery pole or terminal (50) is cold-produced by means of a process comprising axial compression at room temperature of an essentially cylindrical metal element (42) between a first and a second portion of die (1) and (2), travelling one in respect to the other, of which the first (1) forms that which will be the protruding part (13) of battery pole or terminal and the second (2) portion of die, by subjecting lower part of the metal block to compression, achieves the electrical battery pole's lower part, which is provided with shaped portions (35) achieving a number of ribs. |
