9 volt batteries and button cells must be covered with adhesive tape for collection. Fact or fiction?
FACT!
It is true that it is best not to just put 9 volt batteries and button cells loose in a collection cube. But why is that and how does adhesive tape help?
Plus and minus: too close together
Because button batteries are so flat, their positive and negative poles are very close together. If they come into contact with other batteries in the collection cube, such as a 9 volt battery, this can cause a short circuit.
Sticky tape to the rescue
If you cover button cells and the poles of your 9V batteries with a piece of tape, you are covering them with a "protective layer". That way, the risk of a short circuit with other batteries is prevented.
Always cover button cells and 9V batteries when returning them!
Do you have a number of discarded batteries at home? Did you tape your 9V batteries and button cells with a piece of adhesive tape?
