Note on the disposal of used batteries

The following notice is aimed at those who use batteries or products with built-in batteries and no longer resell them in the form delivered to them (end users):

1. Free return of old batteries

Batteries must not be disposed of with household waste. You are legally obliged to return old batteries so that they can be disposed of correctly. You can hand in used batteries at a municipal collection point or at your local store. As a battery distributor, we are also obliged to take back old batteries, although our take-back obligation is limited to used batteries of the type that we carry or have carried as new batteries in our range. You can therefore either send used batteries of the type mentioned above back to us with sufficient postage or hand them in free of charge directly to our shipping warehouse at the address given in the legal notice.

2. Meaning of the battery symbols

Batteries are marked with the symbol of a crossed out garbage can (see below). This symbol indicates that batteries must not be disposed of with household waste. For batteries that contain more than 0.0005 percent by mass of mercury, more than 0.002 percent by mass of cadmium or more than 0.004 percent by mass of lead, the chemical name of the pollutant used is located under the garbage can symbol - where "Cd" stands for cadmium, "Pb " stands for lead and "Hg" for mercury.
