Hi John, Here is some info for you to use to answer this question. The most important consideration is that the battery's CCA rating MEETS OR EXCEEDS, your car's OEM cranking requirement in your climate. CCAs are the discharge load measured in amps that a new, fully charged battery, operating at 0 o F (-17.8 o C), can deliver for 30 seconds and while maintaining the voltage above 7.2 volts. Batteries are sometimes advertised by their Cranking Performance Amps (CA), Marine Cranking Amps (MCA) measured at 32o F (0 o C), or Hot Cranking Amps (HCA) measured at 80 o F (26.7 o C). These measurements are not the same as CCA. Do not be misled by CA, MCA or HCA ratings. To convert CAs to CCAs, multiply the CAs by 0.8. To convert HCAs to CCAs, multiply HCAs by 0.69.]
To start a 4-cylinder gasoline engine, you will need approximately 600-700 CCA; 6-cylinder gasoline engine, 700-800 CCA; 8-cylinder gasoline engine, 750-850 CCA; 3-cylinder diesel engine, 600-700 CCA; 4-cylinder diesel engine, 700-800 CCA; and 8-cylinder diesel engine, 800-1200 CCA. Hope this help you.
