Solution

1. Preparation

Tools Required: Socket set, wrench, battery terminal cleaner, safety gloves, eye protection
Ensure the vehicle is parked on a level surface and the engine is off.
Open the hood and secure it with the prop rod.

2. Disconnect the Old Battery

Safety First: Wear safety gloves and eye protection.
Locate the negative battery terminal (marked with a minus sign).
Using a socket or wrench, loosen the nut on the negative terminal and carefully disconnect it first to prevent any short.
Repeat the process for the positive terminal (marked with a plus sign).

3. Remove the Old Battery

Check for any securing brackets that hold the battery in place, typically located at the base of the battery.
Remove the bracket using the appropriate socket or wrench.
Carefully lift the battery out of the tray, ensuring to use proper lifting techniques due to its weight.

4. Install the New Battery

Positioning: Place the new battery in the tray, ensuring the terminals are in the correct orientation (positive to positive, negative to negative).
Reinstall the securing bracket to hold the battery in place.

5. Connect the New Battery

Start with the positive terminal; place it onto the positive battery post and tighten the nut securely.
Repeat the process for the negative terminal, ensuring it is tight.
Inspect both terminals for any corrosion or loose connections.

6. Final Checks

Close the hood securely.
Start the engine to verify proper installation.
