Solution

1. Preparation

Gather tools and materials needed.
Ensure the vehicle is parked on a flat surface and turned off.
Wear safety goggles and gloves.

2. Disconnect the Battery

Use a socket set to loosen and remove the negative (-) terminal first to prevent short circuits.
Follow with the positive (+) terminal.
Ensure the battery is completely isolated from the electrical system.

3. Remove the Old Battery

Open the trunk and locate the battery compartment; it is usually situated on the right side.
Remove any cover or panel that conceals the battery.
Unfasten the battery securing bracket using the appropriate socket.
Carefully lift the battery out of its compartment; be cautious as it can be heavy.

4. Install the New Battery

Place the new battery in the compartment, ensuring the terminals are positioned correctly (positive to positive, negative to negative).
Secure the battery with the bracket and tighten it using the socket set to the manufacturer's specifications.
Reattach the positive (+) terminal first, followed by the negative (-) terminal.

5. Final Checks

Double-check all connections are secure and free of corrosion.
Replace any cover or panel that was removed.
