What makes a car battery cold cranking amps?
Automotive batteries are rated in “Cold Cranking Amps”. The higher the rating, the more power the battery can produce. If a battery is rated for 700 cold cranking amps (CCA), that means the chemical reaction inside can produce 700 amps for 30 seconds when it is 0oF.
