Andrew,
If the charger is truly making only 2 amps per output, then batteries should not get immediately warm. Either the batteries are defective or the charger is making way more than 2 amps (as in the charge circuit is shorted). Even with defective batteries, the KOP charger takes a while to heat a battery. The documentation talks about the four charge cycles but it doesn't really explain if the charge current is average or maximum. In general, CCA testers put a very low resistance load across the battery. I would be interested to know the model of the tester you use.
