What is the best way to maintain and prolong the battery life of an Audi A2?

I have recently purchased an Audi A2 and want to make sure I am properly maintaining its battery to ensure longevity and prevent any unexpected breakdowns. What are some steps or practices I should follow?

Regularly check the battery terminals for any signs of corrosion and clean them with baking soda and water if necessary. This will ensure good contact and prevent any draining issues.

When parking your Audi A2 for an extended period of time, it is recommended to disconnect the battery to prevent any parasitic drain from electronic components. Just remember to reconnect it before starting the car.

Add a quality battery protector to your routine maintenance. This will not only prolong the life of your battery, but also help with starting your car in extreme weather conditions.
