Step 1: Carefully lift the battery out of the tray. Batteries are heavy, so use proper lifting techniques.
Step 2: Inspect the battery tray for any corrosion or debris and clean if necessary.

4. Install the New Battery

Step 1: Place the new battery into the battery tray, ensuring it is oriented correctly (positive and negative terminals in the correct positions).
Step 2: Reinstall the battery hold-down brackets and tighten to manufacturer specifications using a torque wrench.
Step 3: Connect the positive (red) terminal first. Ensure it is securely attached to the battery post.
Step 4: Connect the negative (black) terminal next. Tighten the terminal clamp securely.
Step 5: Clean any corrosion from the terminals with a battery terminal cleaner or wire brush.

5. Final Checks

Step 1: Close the hood securely.
Step 2: Start the vehicle to ensure the battery is functioning correctly.
Step 3: Check that all electrical systems are operating normally.
