Steps to Replacing Your Car Battery
Replacing your car battery is a relatively simple process that can be completed in just a few steps. First you will need to put your car in park, turn it off and make sure the key is removed from the ignition. Ensure the engine has cooled down then locate your car battery (usually in the front mounted on a metal tray). Then follow the steps below to replace the car battery:
Step 1: Disconnect the Cables
The first step in replacing your car battery is to disconnect the cables. There are two terminals where you will find the cables attached, a positive and a negative terminal. You can tell these terminals apart by:
Positive is usually red and has a + symbol.
Negative is usually black and has a – symbol.
You should always remove the NEGATIVE cable first. To disconnect the negative cable, use your wrench to loosen the nut or bolt on the negative terminal. Once the nut or bolt is loose, carefully remove the negative cable by gently twisting the cable connector as you pull it up. Now you can follow the same process to safely remove the positive cable.
Step 2: Remove the Old Battery
Next, you’ll need to remove the old battery from the car. To do this, you’ll need to use your wrench to loosen the nuts or bolts holding the old car battery in place. Once the nuts or bolts are loose, carefully lift the battery out of the car. You should wear gloves and use caution when lifting and carrying the battery, as it can be heavy.
Step 3: Clean the Battery Tray and Terminals
Once the old battery has been removed, you’ll need to clean the battery tray and terminals. To do this, use a battery brush, steel wool or brush to scrub away any corrosion or dirt on the terminals. You can also use a battery terminal cleaner or some baking soda in a little water to make sure the terminals are completely clean. As you are cleaning you should inspect all the cables and battery terminal to ensure they are in good condition.
Step 4: Install the New Battery
Now that the battery tray and terminals are clean, you can install the new battery. Before placing the battery in the battery tray, make sure the terminal posts are facing the same direction as the old battery. Once the battery is in place, use your wrench to securely fasten the nuts or bolts to the battery terminals.
Step 5: Securely Fasten the Battery
Once the battery is in place, you’ll need to securely fasten the battery. To do this, use the wrench to tighten the nuts or bolts on the battery terminals. Make sure the nuts or bolts are secure, as loose connections can cause electrical problems.
Step 6: Connect the Battery Cables
Now that the battery is securely fastened, you’ll need to connect the battery cables in the reverse order in which you removed them – which means you always reconnect the POSITIVE cable first.
Step 7: Check the Battery and Test Drive
Once the battery is connected and secured, you’ll need to check the battery and test drive the car. To check the battery, start the car and listen for any strange sounds or odours. If everything sounds and smells normal, you can take the car for a test drive to make sure everything is working properly. New car batteries come fully charged so should be ready to go right away. If your engine is still sluggish, lights are dull or you have any other issues, double check all the connections are secured firmly. If this doesn’t fix the problem it may be time to consult an expert!
