What happens when you have too many Cold Cranking Amps?

Answer 1

There is no such thing as too many cold cranking amps! The battery does not push the CCA (cold cranking amperage) but merely has it available to the starter to draw from the battery as the starter needs it. Buying a bigger CCA Battery is a waste of money and may work the alternator a bit harder to keep it charged but will not cause damage to the electronics or starter. The bigger CCA Batteries have their plates closer together which will result in the battery not lasting quite as long but this shorter life may be out weighed by the additional power needed for accessories or cold starting conditions. Along with the CCA (cold cranking amps) the consumer ought to also consider the "AH" rating (know as the AmpHour Rating). This is the specification that tells you how long you can accidently leave the lights on or an accessory on before the battery will be drained dead. >Good AH ratings are somewhere between 41AH & 65AH which will allow the lights to be on for 5 to 10 hours yet still start the vehicle (in average temperature weather).
