How do I properly change the battery in my Audi A5?

I've noticed my car's battery is getting weaker and I want to replace it. However, I've never done this before so I want to make sure I do it correctly. Can someone walk me through the steps?

First, be sure to disconnect the negative cable from the battery before attempting to remove it. Then, loosen the bracket that holds the battery in place and carefully lift it out. Install the new battery by reversing these steps. My personal recommendation is to also clean the battery terminals before reconnecting them to ensure a good connection.

Replacing the battery in your Audi A5 is a simple task. Just be sure to note which side of the battery is positive and which is negative before removing it. My advice is to take a photo of the battery before removing it so you can reference it when installing the new one.
