Step 1
Start by removing the dead car battery from the car. You can get a mechanic to do this for you, or you can do it yourself. This old battery will give you the information you will need to find and choose your new car battery.
-
Step 2
Look at the dead battery and look for the "group size" number, which indicates which cars the battery fits in. It might be difficult to find when you first look, but look at where all of the main information is on the battery.
-
Step 3
Go to your auto parts store and take the make and year of your car with you. These stores usually have books to help you find the correct battery that you need to put into your car. Find the year and model of your car in the book and choose the appropriate battery.
-
Step 4
Make sure you have the right amps for the engine that you are trying to start up. You need the right amount of power to get your engine to start and keep the battery healthy.
-
Step 5
Keep it in mind that you will need the right cranking amps and cold cranking amps if you live in a colder climate. If you own a truck or any other diesel car, then you will need to check what it requires.
