   For a 12V car battery set the voltage to 14.2 - 14.4 and the max   
   current to 5A.   The charge rate (current) will then take care of   
   itself, which is essentially how a car's own voltage regulator does   
   it.   
      
   For a long term maintenance charge you could wind it back to 13.8V.   
      
   For a 6V battery (if you happen to own an old Beetle or a Model T)   
   halve the voltage.
