Batteries are normally sized by criteria such as "group size" and CCA (cold cranking amps). Sometimes vehicles may have mixed installation of battery sizes from the factory, so it's important to identify which size applies to your specific car.
Group size is an industry standard for battery width and height, with some examples being H7, H8 or Group 48. These are all references to the physical dimensions of the battery. To ensure that the battery will physically fit in the car, the group size must match your current battery and is normally stated on the information sticker on the top of the battery.
CCA - cold cranking amps - is the most commonly discussed battery criterion. CCA is the number of amps the battery produces when cold and is often measured to determine a battery's health. CCA ratings can range from as low as 300 up to over 1000. A battery must meet the correct CCA level for your vehicle.
If you're interested in finding a battery that fits your vehicle, head over to fcpeuro.com and start by entering your vehicle into our vehicle selector.
Once your car is added to the selector, there are a couple of important ways that we advise correct fitment.
The first is the "fitment indicator" shown on the Product Page after selecting a part. This box is below the "add to cart button" and has two states. It will either say " Yes this part fits" or "Part may not fit, click to verify".
Sometimes the green box will be accompanied by extra fitment notes. These notes may be independent of the information gathered by the vehicle selector. IE: VIN-specific options, need to be taken into account when determining overall fitment.
