Ricardo from Florida writes by email: “I have a question for you. Would it hurt or be a disadvantage to use a 1,000 CCA-rated battery in a vehicle equipped with a four-cylinder engine? The technician at the shop told me that the standard battery for my 2015 Chevrolet Cruze is 590 CCA. I was told to take the cubic-inch displacement of the engine and double it to arrive at the suggested CCA rating of a battery. However, with just a 2.0-liter (122 cu. in.) engine, this calculation does not seem to apply.
The temperatures here in south Florida are high and I don’t think I need a large battery capacity to start my car even in the winter. The technician also said that the heat causes the battery to lose capacity and installing a high-capacity battery will result in a longer battery life. I don’t want to have a large-capacity battery hurting my car. What is your suggestion?”
