2. Disconnect the Old Battery

Open the hood and locate the battery.
Remove any plastic covers if present.
Disconnect the negative (-) terminal first using a 10mm socket or wrench to prevent short circuits.
Disconnect the positive (+) terminal using the same tool.
If applicable, remove any securing brackets holding the battery in place.

3. Remove the Old Battery

Carefully lift the battery out of the tray; batteries can be heavy, so use proper lifting techniques.
