How Do You Replace a Car Battery?
-
Step 1: Gather Necessary Tools and Materials
Before you start the replacement process, make sure you have the following:
-
Step 2: Park and Turn Off Your Vehicle
Ensure your car is parked on a flat surface with the engine turned off. Engage the handbrake to secure the vehicle in place.
-
Step 3: Locate the Battery
In most vehicles, the battery is located under the bonnet. Refer to your car's manual to find the exact location.
-
Step 4: Disconnect the Battery
Using the wrench or socket set, loosen and remove the negative terminal first, followed by the positive terminal. This minimises the risk of electrical shock.
-
Step 5: Remove the Old Battery
Unscrew the battery bracket and carefully lift out the old battery. Be mindful of its weight, as car batteries can be heavy.
-
Step 6: Clean Battery Terminals
Use a battery terminal cleaner to remove any corrosion from the terminals. Apply a thin coat of terminal protection spray to prevent future corrosion.
-
Step 7: Install the New Battery
Place the new battery in the same position as the old one. Connect the positive terminal first, followed by the negative terminal. Tighten the terminals securely.
-
Step 8: Test the Battery
Start your vehicle to ensure the new battery is functioning properly.
