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.
No, the battery charger has to match the voltage of the battery it is to charge.
