What are the common issues with the battery of the Audi A2?

I have noticed some battery problems with my Audi A2 and I am wondering what could be the cause and what steps should I take to maintain it properly.

One common issue with the Audi A2 battery is its susceptibility to extreme temperatures. It is important to keep the battery within a moderate temperature range to ensure its longevity.

Another common issue is the build-up of corrosion on the battery terminals. Regularly cleaning the terminals with a mixture of baking soda and water can help prevent this.

If you notice that your battery is constantly losing charge, it could be a sign of a faulty alternator. In this case, it is best to get it checked by a professional mechanic.
