Battery Fundamentals: Ah vs. CCA
Ampere-Hours (Ah)
Ampere-hours (Ah) is a unit of electric charge, indicating the amount of current a battery can deliver over a period of time. It's a measure of battery capacity.
- Higher Ah means longer discharge time.
- Commonly used for deep cycle batteries.
Cold Cranking Amps (CCA)
- CCA measures a battery's ability to start an engine in cold temperatures.
- It's the number of amps a 12-volt battery can deliver at 0°F (-18°C) for 30 seconds while maintaining at least 7.2 volts.
- Crucial for starting batteries in vehicles.
Key Formulas (Approximation):
CCA = Ah × 7.25
Ah = CCA / 7.25
Calculation Formulas
Ah to CCA:
CCA = Ah × 7.25
CCA to Ah:
Ah = CCA / 7.25
Example Calculation
Convert 100 Ah to CCA:
Ah: 100 Ah
CCA = 100 Ah × 7.25 = 725 CCA
Result: 725 CCA
Convert 500 CCA to Ah:
CCA: 500 CCA
Ah = 500 CCA / 7.25 ≈ 68.97 Ah
Result: 68.97 Ah
