Caution: Battery runs out when he remains in the charger!

The product idea and uses are super. After extensive testing I have found, however, that the battery will lose if he remains after charging in the cradle. After about 5 days only 87% capacity were available after 2 weeks there were only about 50%. The charger must draw current from the battery therefore constantly. To preserve the 100% state of charge of a freshly charged batteries, you must therefore remove the battery from the holder and store separately. For me this is a design flaw and therefore a KO criterion. - Too bad -
