Battery Capacity
If the battery is being discharged very quickly (i.e., the discharge current is high), then the amount of energy that can be extracted from the battery is reduced and the battery capacity is lower. This is due to the fact the necessary components for the reaction to occur do not necessarily have enough time to either move to their necessary positions.
Battery Cranking Amps
CCA is the amount of current a battery can deliver at 0-degrees Fahrenheit for 30 seconds without dropping below 7.2 volts. Marine Cranking Amps (MCA) is another measure of battery performance, and it shows how well the battery performs in colder temperatures.
