How do I properly maintain my Kia Niro's battery?

I have noticed that my Kia Niro's battery life seems to be decreasing. What are some steps I can take to properly maintain my battery and prolong its lifespan?

Regularly check the battery's fluid levels and top it off if necessary. This will ensure it is not running on low voltage and prolong its lifespan.

Avoid leaving electronic devices plugged in overnight, as this can drain the battery even when the car is turned off.

Consider investing in a trickle charger, especially if you live in colder climates. This will help maintain the battery's charge during long periods of inactivity.
