Hyundai Kona Electric: How to Change the 12V Battery?

[@elmarwinkler3340]

Good to hear the removal does not cause onboard electronics problems! Will do my 2022 Kona this Summer. Cheers.

That battery setup looks very similar to my Kia Niro EV 2019, so this was a great demo I can use when I will be needing to replace my own battery soon.

You make it look so easy mate thank you

Thanks for all the videos on your Kona. They were kinda a review of of the Kona EV for me before i picked up one myself. I like it alot so far, for my work commute. So thanks, by the way, I've used napa batteries for decades and they have been great. My muscle Car and my boat share a Napa battery. No problem

Great content. Thank you for showing this. I have a feeling I'm in for this at some point on my '22 Kona as the wireless charger is no longer working. Hoping to get it dealt with under warranty but we'll see😅

Thanks for posting this, very helpful! I assume everything has been working well since the change?

I'll note that it's important to disconnect 12V power anyway just so that the car can re-assess the 12V battery characteristics, which from my measurements will take a few days. Owners might look for the correct DIN44 metric-size battery, if available. I installed a DIN44-AGM "stop-start" type which has been more resilient than the OEM Rocket. There's also a DIN44-AGM "hybrid auxiliary" type which is less easy to find but even more optimal, such as the Yuasa LN1-MF.

Thank you very much! I suppose that if the battery dies, you can't open the doors automatically... Any problems with the manually opening with the key? And what about the hood? Thank you again!

Thanks for the tips

How did you know it needed changing

[@sunilkumarrai8937]

If negative terminal has a sensor we can direct disconnect the battery ? Otherwise we should use another battery inside the car and then disconnect negative terminal first, right sir? Plz reply

[@harveyrichard2007]

Silly question : why always the -ve terminal first when removing terminals ?

[@DerekRoss1958]

It's to do with accidental short circuits. Following the order given in the video makes it much less likely that you'll cause a short circuit by accidentally dropping a tool or touching something energized.

What is the wrench size?

The 12v Battery on my 2022 Kona EV is dead and the dealership is telling me they are on backorder with NO ETA. I'm currently jumping it with a little portable charger, every time I need to drive.Concerned that if I use a battery from napa etc, it may cause issues down the line. Thoughts anyone?

[@momblame]

No issues - It's 12V battery, the 121R seems to be the right fit for Kona EV - the one from Costco even has greater crank amp rating. I will change mine today, thanks to this video!
