Why is it important to regularly check and maintain the battery in an Audi A2?

I just bought an Audi A2 and I’m wondering why I need to check and maintain the battery regularly. What can happen if I neglect it?

The battery is an essential part of your car's electrical system and is responsible for powering various components such as the lights, radio, and ignition system. Neglecting it can lead to your car not starting or your electronics failing.

Regularly checking and maintaining your battery helps ensure it has enough charge and is functioning properly. This can prevent unexpected breakdowns and costly repairs.
