    Your batteries should have 12.6 volts when fully charged, 2.1 volts per cell X 6 cells = 12.6 volts. Have you had the batteries load tested to make sure they are maintaining the proper voltage while cranking? Too much voltage drop will keep the starter from turning properly; too much current draw from the starter will also cause problems. Are the battery cables tight and in good condition?

    I AGREE, THAT IS FOR EACH BATTERY! WERE BOTH INSTALLED AT THE SAME TIME? DOES ANYONE USE A HYDROMETER ANYMORE?
    YOU HAVE A TOTAL OF 12 CELLS IN 2 BATTERIES, IF ANY CELL IS DEFECTIVE IT WILL AFFECT ALL OTHERS. JUST LIKE YOUR FLASHLIGHT.

    ideally you should have 12.6 voltes, you should start it with 12.0 voltes as long as it does not drop below 9.5 voltes WHILEST cranking
