The battery will attempt to charge the charger since the battery is at a higher voltage than the charger. Thus, the battery will simply discharge and generate heat. If you leave it plugged in long enough, eventually the battery will discharge to a point where it can maintain only 6V, where it will stay until you actually charge the battery.
