Solution

1. Preparation

Gather tools: socket set, multimeter, battery terminal cleaner, safety gloves, and safety goggles.
Ensure the vehicle is parked on a level surface with the engine turned off.

2. Disconnect Battery

Using the socket set, disconnect the negative (-) terminal first, followed by the positive (+) terminal to avoid short circuits.
Remove any battery hold-down brackets securing the battery in place.

3. Remove Battery

Carefully lift the battery out of the tray, ensuring to maintain a proper grip to avoid dropping it.

4. Install New Battery

Place the new battery into the tray, ensuring it is oriented correctly (positive and negative terminals on the appropriate sides).
Secure it with any hold-down brackets removed earlier.

5. Connect Battery

Connect the positive (+) terminal first, followed by the negative (-) terminal.
Tighten the terminals securely but avoid over-tightening, which can damage the battery posts.

6. Final Check

Inspect the installation to ensure everything is connected properly.
Close the hood and start the vehicle to verify the installation.
