How to Extend the Battery Life of My Audi A4?

I've noticed that the battery life of my Audi A4 seems to be decreasing. Is there anything I can do to optimize its lifespan?

First of all, make sure to regularly check your battery voltage and keep it within the recommended range. Avoid draining the battery completely and try to charge it fully. Additionally, minimize the use of electronic accessories when the engine is off.

You can also try using a battery tender or trickle charger when not driving your Audi A4 for extended periods of time. This will help maintain the battery's charge and prevent it from draining too quickly.

Another tip is to keep your battery terminals clean and free from corrosion. Use a mixture of baking soda and water to clean them if needed.
