Step 1: Find your battery group size

Car batteries are divided into group sizes, it indicates batteries length, width and height. If you own a car that has its original battery, you can find the number on the label of the battery. Group sizes are typically a two-digit number and may be followed with a letter. Otherwise, to find the required size for your vehicle, please see the owner’s manual (look under the specifications section) or consult with a mechanic. Battery of the right size should fit the battery tray perfectly and feel secure so that it does not move and get damaged when driving on roads that cause vibrations.

Step 2: Find the required minimum CCA (Cold Cranking Amps)

Battery Capacity is measured in CCA (Cold Cranking Amperes). To learn more about CCA, read our How to choose the longest-lasting car battery blog. To find what CCA is required for your car, see on a label on the top or the side of the current battery case, look for a number followed by “CCA.” If the battery is not original, see the owner’s manual or consult with a mechanic.

Step 3: Determine the battery cell type

Batteries come in three different types: SLI (Starting, Lighting and Ignition), Lithium-Ion (Li-ion) and VRLA (Valve-Regulated Lead-Acid). We explain each one in detail in choosing the correct battery for your car blog. But in simple terms, the vast majority of cars you see on the road use SLI batteries.
