The battery cover is secured in position with T30 bolts, removing all the t30 bolts properly. Before you remove this housing, make sure to wear high-voltage gloves to avoid any electric shocks.

After removing the battery cover, remove the bolts holding the battery power cables in position. You will now see a computer harness on the side of the battery; disconnect that also.

Open the car’s trunk, go to the backside, and remove all the covering to see the steel plate holding the battery. You will see two 12 mm nuts below the rubber recess; remove them too.

Go to the front side again and remove the other four nuts which hold the battery, and you should see the battery coming loose. Slowly pull the battery out.

Step 5: Replace the battery

Simply insert the new battery in position and secure it using the same four nuts and reconnect the computer harness and power cables. Make sure to connect everything in the same way as you have disconnected the battery.

Once the battery installation is complete, check every connection and start your engine. The battery should be working fine.
