     No most 12 volt car battery chargers operate at 13.6 VDC.  That is the   
   CHARGE Voltage, not the voltage the battery ends up carrying.  In order   
   to charge a battery, one must apply a higher voltage than the battery   
   operates at.

     You're an idiot.  A car battery or 12V gel cell that reads 12volts IS   
   fully charged and will put out its declared rate.

     You're an idiot.  Perhaps you should provide a wiki citation or such.   
   Right now you appear as a joke.
