Use a socket wrench to loosen the negative (-) terminal first and remove it.
Follow with the positive (+) terminal.

3. Remove the Old Battery

If applicable, remove any hold-down bracket securing the battery.
Carefully lift the battery out of the tray (batteries can be heavy).

4. Clean the Battery Tray and Terminals

Clean any corrosion from the battery terminals using a wire brush.
Wipe down the battery tray with a cloth and mild cleaning solution.

5. Install the New Battery

Place the new battery into the tray, ensuring it is seated securely.
Reinstall the hold-down bracket if applicable.

6. Reconnect the Battery
