Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect any accessories connected to the battery.

2. Disconnect the Old Battery

Safety First: Disconnect the negative terminal first (usually marked with a “-”).
- Use a wrench to loosen the nut on the negative terminal and remove the cable.
- Secure the cable away from the battery.
Disconnect the Positive Terminal:
- Loosen the nut on the positive terminal (marked with a “+”) and remove the cable.
Remove the Battery Hold-Down Clamp:
- Locate and remove any clamps or brackets holding the battery in place using the appropriate wrench.

3. Remove the Old Battery

Lift the Battery Out:
- Carefully lift the battery out of the tray. Batteries can be heavy, so use proper lifting techniques.
- If the battery is stuck, gently rock it to break any corrosion or debris seal.

4. Install the New Battery

Place the New Battery:
- Position the new battery in the tray, ensuring it is oriented correctly (positive and negative terminals align).
Secure the Battery:
- Reinstall the battery hold-down clamp to secure the battery in place.

5. Connect the New Battery

Connect the Positive Terminal:
- Attach the positive terminal first, tightening the nut securely.
Connect the Negative Terminal:
- Attach the negative terminal and tighten it securely.
Final Check:
- Ensure that both terminals are tight and free of corrosion.
