Use a wire brush or terminal cleaner to remove any corrosion from the battery terminals.
Ensure the terminals are clean and dry before reconnecting.

3. Replace Battery (if necessary)

Remove Old Battery:
- Unscrew and remove the battery hold-down bracket.
- Carefully lift the battery out of the tray (ensure to maintain proper lifting posture).
Install New Battery:
- Place the new battery into the tray, ensuring it is oriented correctly.
- Reattach the hold-down bracket and tighten it to secure the battery.
Reconnect Battery Cables:
- Connect the positive terminal first, followed by the negative terminal.
- Ensure connections are tight to prevent any electrical issues.

4. Dispose of Old Battery
