...which is why I said in my previous post that changing the CCA setting on that tester doesn't change the load, it just changes the way the tester computes and reports the battery's health: Presumably if you've told the tester that the battery under test is 500 CCA it expects to see a somewhat higher voltage under load than for a 200 CCA battery.
