[TR] Battery trickle charger

I replaced a 12 volt battery in my RV (for towing the Spitfire race  
car) with two six volt batteries (to get more amp hours/storage) wired  
in series to get 12 volts. Question is do I charge it with a 6 volt  
or  12 volt charger? Maybe 12 if I hook the charger to where the pos  
and neg cables attach.
