How to extend the lifespan of my Audi A6 battery?

I have noticed that my Audi A6 battery is not lasting as long as it used to. Is there anything I can do to prolong its lifespan?

Firstly, make sure to regularly check the battery's electrolyte levels and top it up if needed. This will help prevent sulfation and prolong its lifespan.

You could also invest in a good quality battery charger and use it to maintain your battery's charge when the vehicle is not in use for extended periods of time.

Avoid using electronics in your Audi A6 for long periods of time when the engine is not running. This can drain the battery quickly and shorten its lifespan.
