Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative terminal of the battery to prevent any electrical shorts.

2. Remove Battery

Using a socket set, loosen and remove the positive terminal first, followed by the negative terminal.
Remove any battery hold-down brackets using the appropriate socket.
Carefully lift the battery out of the battery tray, ensuring to keep it upright.

3. Inspect and Clean

Inspect the battery tray for corrosion; clean it with a wire brush if necessary.
If installing a new battery, ensure the new battery matches the specifications (size, capacity).

4. Install New Battery

Place the new battery into the tray and secure it with the hold-down brackets.
Connect the positive terminal first, followed by the negative terminal.
Ensure all connections are tight and free of corrosion.

5. Test Battery and System

Reconnect the negative terminal last.
Start the vehicle and check the dashboard for warning lights.
Measure the battery voltage again to ensure proper charging.
