How do I know if my Kia Sportage needs a battery replacement?

I have a Kia Sportage and it's been having some trouble starting lately. I'm wondering if it's time to replace the battery. What are some signs that indicate the battery needs to be replaced?

If your Kia Sportage is taking longer than usual to start, it could be a sign that the battery is losing its charge.

Another indication that your battery may need to be replaced is if your headlights or interior lights seem dim.

You can also check the battery's voltage with a multimeter. A reading of less than 12.4 volts means it's time for a replacement.
