Question: what is the difference between cranking amps and amp hours?
Answer: Cold cranking amps (CCA) is a measurement of the number of amps a battery can deliver at 0°F for 30 seconds and not drop below 7.2 volts. So a high CCA battery rating is especially important in starting battery applications, and in cold weather. ... An amp hour (AH) is a rating usually found on deep cycle batteries.
