Park Your Car in a Safe Place

Park your car in a safe and flat area, away from traffic. Turn off the engine and the headlights, and engage the emergency brake. Ensure that the car is in park or neutral and that the keys are out of the ignition.

Disconnect the Battery

Using a wrench or pliers, loosen the bolts that hold the battery in place. Start with the negative terminal, marked with a minus (-) sign, and then move on to the positive terminal, marked with a plus (+) sign. Once you have loosened the bolts, gently lift the battery out of the car.

Clean the Battery Area

Before installing the new battery, clean the battery area using a wire brush and a battery cleaner. This will remove any corrosion and dirt that may have accumulated over time.

Install the New Battery

Place the new battery in the same position as the old one. Make sure that the positive and negative terminals match the correct cables. Tighten the bolts that hold the battery in place, starting with the positive terminal first and then the negative terminal.

Test the New Battery

Start the engine and let it run for a few minutes. Check that the battery is working correctly by turning on the headlights and testing the electrical system. If everything works correctly, you have successfully changed your car battery!
