A method for operating an electric gardening and/or forestry apparatus system having an accumulator, a gardening and/or forestry apparatus with an electric motor, and a protective electronic circuit including inputs which are connected to the accumulator, outputs which are connected to the gardening and/or forestry apparatus, and a switching element which is disposed in a power path between one of the inputs and one of the outputs. The method turns on the switching element to a first conductive condition, measures an electric current through the power path, turns off the switching element to a second conductive condition, if the measured electric current exceeds a predetermined current limit value, measures an electric output voltage between the outputs, and either again turns on the switching element to the first conductive condition, if the measured electric output voltage reaches and/or exceeds a predetermined voltage limit value, or outputs an error signal, if the measured electric output voltage is below the predetermined voltage limit value.
