- Safety gloves
- Safety goggles
Ensure the vehicle is parked on a level surface and turn off the ignition.
Open the hood and locate the battery.

2. Disconnect the Old Battery

Safety Warning: Disconnect the negative terminal first to prevent electrical shorting.
Using a 10mm socket, loosen the bolt on the negative battery terminal and remove the cable. Secure it away from the battery.
Repeat the process for the positive terminal.

3. Remove the Old Battery

Check for any securing brackets or clamps holding the battery in place and remove them using the appropriate tool.
Carefully lift the battery out of the tray. Batteries can be heavy; use proper lifting techniques.

4. Clean the Battery Tray and Terminals

Inspect the battery tray for corrosion or debris and clean it using a battery terminal cleaner or wire brush.
If corrosion is present on the battery cables, clean them as well to ensure a good connection with the new battery.

5. Install the New Battery

Place the new battery in the tray, ensuring it is oriented the same way as the old battery.
Reattach any securing brackets or clamps to hold the battery in place.

6. Connect the New Battery

Connect the positive terminal first by placing the cable on the positive terminal and tightening the bolt securely.
Connect the negative terminal next, ensuring a tight connection.
Safety Warning: Ensure the cables are not touching each other or any metal parts.

7. Final Checks

Close the hood and start the vehicle to ensure that the battery is functioning properly.
Check for any warning lights on the dashboard related to the battery or charging system.
