What is the cause of Kia Niro's battery draining quickly?

I have recently noticed that my Kia Niro's battery drains quickly. What could be causing this issue and how can I fix it?

One possible cause could be a malfunctioning alternator. It's important to have it checked and replaced if necessary to avoid further issues.

Another potential cause could be an old or faulty battery. It's recommended to have it tested and replaced if needed to ensure proper functioning of your vehicle.

A dirty or corroded battery may also lead to faster draining. Make sure to clean your battery terminals regularly to avoid this issue.
