Or are they both charging at 15 amps? BTW I got an astonishing nine years out of my last set of Costco interstate batteries. I had a load test performed on the deceased and one rated good, the other was toast as I mistakenly set the smart charger to charge at 40 amps.
The answer is "depends" in a perfect world both would receive 7.50amps....... The way the batteries are wired play a large role on charge and discharge behavior. Here is some homework if you are interested.Good stuff here
