Solution

1. Preparation

Tools Required:
- Socket set
- Torque wrench
- Multimeter
- Wire brush or battery terminal cleaner
- Safety gloves and goggles
Disconnect the vehicle's ignition to prevent any electrical shorts.
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Remove the Old Battery

Open the hood and locate the battery, which is usually on the left side of the engine bay.
Use the socket set to loosen and remove the negative (-) battery terminal first. This prevents any short circuit when removing the positive terminal.
Repeat the process for the positive (+) battery terminal.
If your model has a battery cover, remove it by unscrewing or unclipping any securing elements.
Remove any securing brackets or straps holding the battery in place using the socket set.
Carefully lift the battery out of the tray; batteries can be heavy, so ensure to lift with proper posture.

3. Clean and Prepare the Battery Tray

Inspect the battery tray for corrosion or debris. Clean it using a wire brush or battery terminal cleaner.
If corrosion is present, apply a corrosion inhibitor to prevent future buildup.

4. Install the New Battery

Place the new battery into the tray, ensuring the terminals are positioned correctly (positive to positive, negative to negative).
Secure the battery with the original brackets or straps, tightening to the manufacturer's torque specifications.
Connect the positive (+) battery terminal first. Tighten securely with the socket set.
Connect the negative (-) battery terminal next, ensuring it is also tightened securely.

5. Final Steps

If applicable, replace the battery cover.
Start the engine to ensure the battery is functioning properly and that all electrical systems are operational.
Reset any electronic systems that may have lost power.
