How do I disconnect the battery in an Audi A7?

I need to disconnect the battery in my Audi A7 to do some maintenance work. Can you guide me through the steps?

To safely disconnect the battery in an Audi A7, first make sure the ignition is turned off and the key is out of the ignition. Next, locate the negative battery terminal, which is usually marked with a minus sign (-). Use a wrench to loosen the bolt that holds the negative cable in place, and then carefully remove the cable from the battery. Repeat the same steps for the positive cable. Remember to wear gloves to protect your hands from any corrosive materials.

Before disconnecting the battery, it's important to take a picture or make note of the battery's orientation in the car. This will help you reconnect it correctly later on. Once the cables are disconnected, make sure they are secured and won't accidentally touch the battery terminals. You can use a battery terminal protector or electrical tape to cover the exposed terminals. When you're ready to reconnect the battery, start with the positive cable and then the negative cable. Double check to make sure everything is securely attached.
