What are the most common issues with the Audi A6's battery life in extreme weather conditions?

I recently bought an Audi A6 and have noticed a significant decrease in battery life during extreme weather conditions such as hot summers or cold winters. What could be causing this and how can I prevent it?

Battery life can be greatly affected by temperature changes. Extreme heat or cold can cause the battery to drain faster or struggle to hold a charge. The best way to prevent this is by keeping your battery well-maintained and regularly checking its voltage and fluid levels.

One common issue with the Audi A6's battery is a faulty alternator, which can cause the battery to not charge properly. It's important to have your alternator checked and replaced if necessary to ensure optimal battery performance.
