Use a battery terminal cleaner or a mixture of baking soda and water to scrub the battery terminals and cable ends.
Rinse with clean water and dry thoroughly before reconnecting.

4. Install New Battery

Place the new battery in the tray, ensuring it is oriented correctly.
Reattach the hold-down bracket and tighten to secure the battery.
Connect the positive terminal first (red cable), followed by the negative terminal (black cable).
Ensure that both connections are tight and check for any corrosion.
