How to troubleshoot a battery problem in a Kia Picanto?

I have been experiencing some issues with my Kia Picanto's battery. Sometimes it fails to start and I have to jumpstart it. What could be the possible cause of this problem and how can I fix it? Any suggestions would be highly appreciated.

It's possible that your battery is simply old and needs to be replaced. Consider checking its age and if it's more than 3-4 years old, it's recommended to replace it.

Another common cause is a bad connection between the battery terminals and the cables. Make sure to clean them and tighten them properly.

It could also be an issue with the alternator not properly charging the battery. Have it checked by a mechanic to ensure it's functioning properly.
