Notes according to the Battery Act (BattG)
Batteries must not be disposed of with normal household waste. As an end user, you are legally obliged to return/properly dispose of used batteries.
After use, you can return the batteries free of charge to the point of sale or in the immediate vicinity (e.g. to collection points in stores or to municipal collection points). You can also hand in the used batteries to us free of charge or send them back to us by post (TEQneers GmbH & Co. KG, Wankelstr. 14, 70563 Stuttgart).
Batteries containing pollutants are marked with a symbol consisting of a crossed-out garbage can and the chemical symbol of the heavy metal that determines whether the battery contains pollutants. Cd stands for cadmium, Pb for lead and Hg for mercury.
You will also find this information again in the accompanying documents for the shipment.
