How To Convert Cold Cranking Amps (CCA) To Amp Hours (Ah)?

If you’ve ever wondered how to convert cold cranking amps (CCA) to amp hours (Ah), you’re in the right place. In this quick and easy guide, we’ll show you how to make the conversion so you can understand your car battery’s true capacity. Let’s get started!

What Are Ampere Hours (Ah)?

Ampere hours, or amp hours, are a unit of measurement that indicate how much electrical charge a battery can hold. The amount of charge a battery can hold is determined by the size of the battery, as well as the type of battery. A battery with a higher amp hour rating will be able to hold more charge than a battery with a lower amp hour rating.

The term amp hour is often used to describe the amount of charge a battery can hold over time. For example, a battery with a rating of 100 amp hours can provide 1 amp of current for 100 hours, or 2 amps of current for 50 hours. The amp hour rating of a battery is usually printed on the battery itself.

Amp hours are often confused with cold cranking amps, or CCA. However, CCA is a measure of the amount of current a battery can provide in short bursts, while amp hours are a measure of the total amount of charge a battery can hold.

What Are Cold Cranking Amps?

Cold cranking amps, or CCAs, are a measure of a battery’s ability to start an engine in cold weather. The higher the CCA, the more power the battery can provide to start the engine. Amp hours, or Ah, is a measure of a battery’s capacity. The higher the Ah, the more energy the battery can store.

Must Read

-Determine the battery’s cold cranking amps. This is usually listed on the battery itself.
-Divide the battery’s cold cranking amps by the voltage. For a 12 volt battery, this would be 12 divided by the cold cranking amps.
-Multiply the resulting number by the amp hours. This will give you the equivalent number of amp hours.
