The batteries and accumulators must not be disposed of with household waste; you are legally obliged to return used batteries and accumulators. Used batteries may contain harmful substances which, if not stored or disposed of properly, could harm the environment or your health. However, batteries also contain important raw materials such as iron, zinc, manganese, or nickel and can be recycled. After use, you can either send us the batteries or return them free of charge in the immediate vicinity (for example, in stores or at municipal collection points or at our shipping warehouse). The sale in retail stores is limited to end users for quantity.
