How should I maintain the battery life of my Audi A4?

I have recently purchased an Audi A4 and I want to make sure that the battery life is maintained properly. What steps should I take to preserve the battery life of my car?

First, make sure to regularly check the battery's voltage and charging system to ensure it is functioning properly. You can do this yourself or take it to a trusted mechanic for maintenance checks.

Avoid leaving your car unused for extended periods of time, as this can drain the battery. If you know your car will be sitting for a while, invest in a battery tender to keep the charge level stable.
