ACDelco recommends the right balance of Cold Cranking Amps (CCA) and Reserve Capacity (RC). A higher CCA battery will not start your car faster. This is due to gear reduction starters, lower viscosity oils, fuel injection, etc. The average car cranks no more than 3 seconds and as a result does not need more CCA than what the vehicle manufacturer recommends. With the addition of vehicle electronics, Reserve Capacity (RC) is becoming more important. Select a battery that has the right amount of CCA, found in your Owner’s Manual, and as much RC as you can.
