   If that was a 12.5 volt battery (6 cell) his meter should not show 13.6   
   volts if it was correct .  However the testers will put a heavy load on   
   the battery and it should not drop but maybe 2 to 4 volts depending on   
   the tester and the load it puts on the battery..  The less the better.   
   If it drops more than that the battery is on its way to going bad.   
   Simple volt meters tell almost nothing about a battery.  They often have   
   the rated voltage without a load. They must be put under a load.  The   
   more the voltage drops for the same type of battery the worse it is.
