Storage batteries having a rechargeable battery for operating electric tools often have a state of charge indicator. A state of charge circuit, which has a sensor that is coupled to the evaluation unit, is provided in order to identify the operating state of the storage battery. An interlock switch for preventing indication of the state of the charge is coupled to the evaluation unit. If charging or discharging of the rechargeable battery is identified using the sensor, the interlock switch is used to prevent indication of the current state of charge. |
