Please note: since our deliveries may contain batteries (single-use and rechargeable),
according to the German Law on Batteries (BattG) we must advise you of the following:
single-use and rechargeable batteries must not be disposed of along with domestic waste, but rather you are legally required to return used batteries. Used batteries may contain damaging substances which, if not stored or disposed of appropriately, may damage the environment or your health. Batteries may, however, also contain important raw materials, such as, for example, iron, zion, magnesium or nickel, which can be recycled. Once used, you may either send the batteries back to us, or return them in
your vicinity (e.g. at the shop, communal recycling points or at our expedition warehouse) - free of charge. When returning used batteries to points of sale, the quantity you are allowed to return is limited to the quantity typical for a single end user, and to those batteries which the seller offers or used to offer in their product range.
