How do you change the car battery in an Audi A1?

I am having difficulty finding the location of the car battery in my Audi A1 and I need to replace it. Can someone provide instruction on how to safely and properly change the car battery in an Audi A1?

To change the car battery in an Audi A1, locate the battery under the hood and use a battery wrench to loosen the terminals. Once the terminals are loose, remove the old battery and replace it with a new one following the same steps in reverse. Always be sure to wear protective gloves and goggles while working with a car battery.
