How do I replace the battery of my Audi A2?

I have noticed that the battery of my Audi A2 is not working properly and I need to replace it. Can someone guide me through the steps to do so?

Replacing the battery of your Audi A2 is a relatively simple process. First, make sure the car is turned off and the key is removed from the ignition. Then, locate the battery, which is typically located under the hood. You may need to remove a plastic cover to access it. Once you have located the battery, use a wrench to remove the negative (-) and positive (+) terminals. Then, carefully remove the battery from the car. Install the new battery in the same position, and reattach the terminals in the correct order. Make sure they are securely tightened. Finally, start the car to ensure the battery is working properly.
