You are misinterpreting the battery ratings; the amperage capacity is a rating of the amps the unit can deliver over a period of time (total capacity), not its actual momentary amp delivery. Most of the batteries that came with the Boxsters are rated at 600-800 CCA, but actually can only deliver 50-80 amps in 10 seconds……. If it could deliver 600 amps instantaneously, your battery cables and starter would not survive…………
