Example of Ah to CCA Calculations

To convert ampere-hours (Ah) to cold cranking amps (CCA), the same approximation can be used but in reverse. The commonly used approximation is:

CCA≈Ah×7.25

This estimation can vary depending on the specific battery and its design.

Below is a table showing the conversion of various Ah values to CCA, sorted from smallest to largest.

Ah	CCA	Ah	CCA
1.00	7.25	10.00	72.50
20.00	145.00	30.00	217.50
40.00	290.00	50.00	362.50
60.00	435.00	70.00	507.50
80.00	580.00	90.00	652.50
100.00	725.00	120.00	870.00
150.00	1087.50

To convert 1 Ah to CCA:

CCA=1×7.25=7.25 CCA

To convert 10 Ah to CCA:

CCA=10×7.25=72.5 CCA

To convert 60 Ah to CCA:

CCA=60×7.25=435 CCA

To convert 80 Ah to CCA:

CCA=80×7.25=580 CCA

To convert 100 Ah to CCA:

CCA=100×7.25=725 CCA
