The ideal Cold Cranking Amperage (CCA) for a car is best between 350A and 600A; it could be higher for trucks and bigger vehicles. You need to be aware of the CCA rating of your car’s battery. Knowing the CCA rating will help you buy the most suitable battery for replacement when you need to do so. It is best to buy a battery with a CCA equivalent to that of your original battery or one with something higher. It helps to ensure optimal or higher performance.
