The official recycling symbol is the circle with 3 round arrows. Batteries that still contain heavy metals are covered by European Directive 157 and must be marked with a special logo (crossed-out wheelie garbage can). These logos should encourage consumers to return the battery instead of simply throwing it away in the garbage garbage can.
This month was THE boat reveal of TU Delft’s Hydro Motion Team and we are proud battery sponsors there. See below the boat the students designed themselves, which contains the battery.
