A cycling device for conditioning battery cells of different types. A selector allows an operator to select the type of the cells to be conditioned. The amplitudes of trickle, discharge and charging currents are automatically selected in response to an output signal from the cell type selector. A control circuit determines the sequence of occurence of the trickle, discharge and charging currents and produces discharge and charge logic conditions, which control circuit includes a timer which delivers a clock signal and which interrupts the charging current after the same has been supplied to the battery cells during a predetermined period of time. Proper discharge operation of the cycling device is indicated only when both the discharge logic conditions are present and the discharge current is detected, while proper charge operation is indicated only when, simultaneously, the charge logic conditions are present, the charging current is detected, and the clock signal is produced by the timer. A detector indicates opening of the circuit through which flow the trickle, discharge and charging currents. The battery cells are so conditioned that at least some of the problems associated with their general use with lack of care, for example crystal growth, lost of internal contact with the sintered plates, etc. are cancelled. The original characteristics of the cycling device can also be applied to a battery cell charger.
