What is the best way to replace the battery in an Audi 80?

I need to replace the battery in my Audi 80, but I'm not sure how to do it properly. Can someone guide me through the process and also provide some tips and tricks?

The first step is to make sure your car is parked on a level surface and the engine is turned off. Then, remove the negative cable from the old battery followed by the positive cable. After that, remove the old battery and clean any corrosion off the terminals and battery tray. Finally, install the new battery and attach the positive cable then the negative cable.

Before installing the new battery, it's important to make sure it has the correct specifications for your Audi 80. Also, be sure to securely tighten the cable connections and apply a small amount of petroleum jelly to the terminals to prevent corrosion.
