Amp Hour to CCA Calculator

Formula

To calculate the CCA from amp hours and the conversion factor:

\[ CCA = Ah \times CF \]

Where:

\(CCA\) is the Cold Cranking Amps
\(Ah\) is the Amp Hours
\(CF\) is the Conversion Factor

What is Amp Hour to CCA Conversion?

Amp hour to CCA conversion is a method used to estimate the cold cranking amps (CCA) of a battery based on its amp hour (Ah) rating and a conversion factor. This conversion is useful for understanding the starting power of a battery, especially in cold conditions. The CCA rating indicates how many amps a battery can deliver at 0°F for 30 seconds while maintaining a voltage of at least 7.2 volts for a 12-volt battery. The conversion factor varies depending on the battery’s design and chemistry.

Example Calculation

Let's assume the following values:

Amp Hours (\(Ah\)) = 50
Conversion Factor (\(CF\)) = 7.2

Using the formula:

\[ CCA = 50 \times 7.2 = 360 \text{ amps} \]

The Cold Cranking Amps (CCA) is 360 amps.
