How do I maintain the battery of my Audi A2?

I recently purchased an Audi A2 and I'm wondering how I can properly maintain the battery to ensure it lasts a long time. Can you provide some tips and advice?

To maintain the battery of your Audi A2, it's important to regularly clean the terminals with a mixture of baking soda and water. This will prevent any build-up of corrosion and ensure proper electrical connections.

Another important step is to avoid leaving your car idle for long periods of time. This can drain the battery and decrease its lifespan. Consider investing in a battery trickle charger if your car will be sitting for extended periods.
