The device contains a pulse generation circuit, a frequency generation circuit, a voltage detection circuit, and a frequency control circuit. A positive terminal of a lead-acid battery of a motor vehicle is connected to the pulse generation circuit and the voltage detection circuit. The pulse generation circuit is connected to the positive terminal of the battery, the frequency generation circuit, and the frequency control circuit. The frequency generation circuit is connected to voltage detection circuit, the frequency control circuit, and the pulse generation circuit. The voltage detection circuit is connected to the positive terminal of the battery, the frequency generation circuit, and the frequency control circuit. The frequency control circuit is connected to the voltage detection circuit, the frequency generation circuit, and the pulse generation circuit.
