How to extend the lifespan of my Audi A2 battery?

I have noticed that my Audi A2 battery is not lasting as long as it used to. I want to ensure that I am doing everything I can to prolong the lifespan of my battery. Are there any maintenance or usage tips that can help me achieve this?

First off, make sure to regularly inspect and clean your battery terminals. Debris and corrosion can build up and affect the battery's performance. Also, try to avoid short trips where the battery doesn't have enough time to fully charge.

Using electronic accessories while the engine is off can also drain the battery. To avoid this, turn off all electronic devices when the engine is not running. Another helpful tip is to invest in a battery tender, which can maintain the charge of your battery when the car is not in use.
