Important information on the correct handling of 9-volt batteries

All 9-volt dry batteries are atmospheric oxygen batteries, which means they need oxygen to develop energy. Before using the device for the first time, it is essential to remove the label to open the air inlets. If the battery is not used for an extended period, the air inlets should be closed again and the battery should be stored in a dry and cool place. In this way, self-discharge is avoided and battery life is extended.
