   There is also C:  Put the positive on the recipient car last because you   
   have less chance of accidentally shorting the circuit & there is no   
   hydrogen there.   
      
   Of A and B, they might both be logoical but B is more important.   
   Shorting the donor battery, even at the other car, is going to cause a   
   lot more trouble, cause a lot more damage, than hydrogen gases.  That's   
   why B is recommended.   
      
   Usually the guy helping me is also putting the cables on his car, but I   
   still look at them before I finish my car.   For various reason, I've   
   had many dead batteries.  Once a pretty girl stopped to give my car   
   battery a jump.
