How do I extend the battery life of my Audi A8?

I've noticed that the battery on my Audi A8 doesn't last as long as it used to. Is there anything I can do to extend its lifespan?

Regularly maintain your vehicle's battery by checking its voltage and keeping it clean. Also, try to avoid short trips and always use a battery maintainer when your car is not in use.

Make sure to turn off all electrical devices when your car is not running, including headlights, interior lights, and the radio. This can prevent unnecessary drain on the battery.
