How do I replace the battery in an Audi A6?

I recently purchased a used Audi A6 and I've noticed the battery is starting to lose its charge. How can I replace the battery in my car?

To replace the battery in an Audi A6, first make sure the car is turned off and the key is removed from the ignition. Next, locate the battery in the engine compartment. Disconnect the negative terminal first, followed by the positive terminal. Remove any hold-down brackets and pull the battery out. Install the new battery in the reverse order, making sure the terminals are connected securely.

One important tip when replacing the battery in an Audi A6 is to avoid touching the battery terminals with bare hands. The oil and dirt from your skin can damage the terminals or cause poor electrical connections. Always wear gloves when handling the battery.
