Find Your Car Battery Group Size
Car batteries are all sorted by a group size. Group size is typically based on your vehicle’s make, model and engine type. It indicates the measurements of the battery case as well as the orientation of the battery terminals or posts. Although some vehicles may accommodate a battery from more than one group size, it is important that you use a battery approved for use in your vehicle. Make make sure your new battery will fit the proper CCA according to the vehicle manufacturer’s specifications. Consult a Battery Guyz local representive to find the battery group size that works for your vehicle.
Step: 1 Check for the group size on your old battery. If the battery that originally came with your car is still in it, look for the group size on a label on the battery. The label may be on the top or on the side of the case. Group sizes are typically a two-digit number and may be followed with a letter.
Step: 2 Check your owner’s manual for a group size. Look under the specifications section in your owner’s manual. The battery group size as well as other pertinent battery information will be in the specs.

Your vehicle requires a certain amount of amperage to start, especially in cold weather. If your battery doesn’t have sufficient amperage to turn over in cold weather, it won’t start and you’ll be stranded.
Step 1: Look on your battery’s label. On a label on the top or the side of the battery case, look for a number followed by “CCA.” If the battery isn’t original to the car, you’ll need to verify that this number is accurate. The label may be faded or illegible. You may have to find the CCA through another method.
Step 2: Check your manual. Check your owner’s manual specifications for a minimum CCA rating.
Step 3: Find a battery with a high rating. If you live in a cold climate with several months well below the freezing point, you may want to look for a battery with a higher CCA rating for easier cold-weather starts. Likewise, If you live in a hot climate with several months well above 100 degrees point, you may want to look for a battery with a higher CCA rating for easier.
