1. Preparation

Gather necessary tools and safety equipment.
Tools Required:
- Multimeter
- Battery terminal cleaner or wire brush
- Safety gloves and goggles
Safety Warnings:
- Disconnect battery before working on electrical systems.
- Avoid open flames near the battery due to explosive gases.

2. Remove the Battery

Open the hood and locate the battery.
Disconnect the negative terminal (black) first, then the positive terminal (red).
Remove any securing brackets or straps holding the battery in place.
Carefully lift the battery out of the tray.

3. Inspect and Clean

Inspect the battery for physical damage or leaks.
Clean the battery terminals and cable connectors with a battery terminal cleaner.
Ensure no corrosion is present; if found, remove it thoroughly.

4. Install New Battery

Place the new battery into the tray and secure it with brackets or straps.
Connect the positive terminal first (red), followed by the negative terminal (black).
Tighten terminal connections to ensure a solid contact without over-tightening.

5. Final Checks

Ensure all tools are removed from the engine bay.
Start the vehicle to check for proper functioning of electrical components.
