What is the best way to prolong battery life in an Audi A2?

I have noticed that the battery in my Audi A2 doesn't last very long. What are some specific tips or hacks for extending its life and avoiding unexpected dead batteries?

To get the most out of your battery, try to limit short trips and avoid excessive use of electrical components. This will help the battery fully charge and prevent unnecessary strain on it.

Always make sure to turn off all lights and electronics before exiting the car and lock it properly. This will prevent draining the battery while the car is not in use.
