WebApr 3, 2024 · there is no way to convert cca to ah directly because there is no correlation between them. but for a rule of thumb, you can divide the cca by 7.25 to get the calculated ah. for instance, if your battery is marked with a 1450 cca, it represents 200 ah. a battery of this rating should last for 25 hours while producing power of 8 amps. WebNov 4, 2024 · To test the CCA with a carbon pile, a battery that must have an SoC of 70 to 100 percent. It is then loaded with half the rated CCA for 15 seconds at a temperature of 10º C (50º F) and higher. As an example, a 500 CCA battery will discharge at 250A for 15s, and the battery passes if the voltage stays above 9.6V.
