Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the negative (-) battery terminal first to prevent electrical shorts.

2. Remove Old Battery

Sub-steps:
1. Using a wrench, loosen the clamp on the negative (-) terminal and remove the cable from the battery.
2. Repeat for the positive (+) terminal, ensuring both are completely disconnected.
3. Locate and remove any retaining brackets or clamps holding the battery in place using a socket set.
4. Carefully lift the old battery out of the battery tray, taking care not to spill any battery acid if it is a flooded battery.

3. Clean Battery Tray and Terminals

Sub-steps:
1. Inspect the battery tray for debris or corrosion and clean it with a wire brush if necessary.
2. Clean the battery terminals with a mixture of baking soda and water to neutralize any corrosion.

4. Install New Battery

Sub-steps:
1. Place the new battery into the battery tray, ensuring it is oriented correctly (positive and negative terminals match).
2. Reattach any retaining brackets or clamps to secure the battery in place.
3. Connect the positive (+) terminal first, followed by the negative (-) terminal.
4. Tighten the terminals securely to ensure a good connection without over-tightening.

5. Final Checks

Sub-steps:
1. Start the vehicle to ensure it runs smoothly.
2. Check for any warning lights on the dashboard regarding the electrical system.
