A system for cycling battery cells with pressure regulation is disclosed. The system comprises supports for receiving the battery cells which insert in a clamping arrangement having jaws moving one with respect to the other by an actuator operated by a controller in order to apply a pressure in a pressure application axis to the cells. A pressure sensor measures the pressure applied to the cells while a cycling module connected to the cells performs their cycling and measures their charge and discharge level. A programmable processing unit ensures a control of the pressure and, if desired, the temperature applied to the cells according to a programmed cycling mode and records data representative of the pressure and other cycling measurements.
