Choosing the correct battery CCA depends on your vehicle type, engine size, and climate. Manufacturers usually recommend a minimum CCA rating. Using a battery with too little CCA can cause starting issues, while excessively high CCA is usually safe but may cost more. Matching battery CCA to your car ensures balanced performance and long-term reliability. https://manlybattery.com/battery-tools-and-resources/battery-cca-to-ah-calculator/
