How long do these batteries really last…?

I just got a 2024 Kia Niro Wind and I love it so far. But something weird happened—the dealer cut the 10-year factory warranty in half because I’m the second owner. I’m a bit concerned, but I guess this is standard. Just wondering, how many miles can these go before the battery isn’t worth keeping or fixing?

I have a 2022 E-Niro with 100k miles and the battery is still charging fine with no noticeable drop in range. The 12V battery has been replaced twice, and the brakes squeal sometimes, but other than that, no major issues.

The high-voltage battery will probably outlast the rest of the car. Seriously, by the time you hit 200k miles, you’ll have worn-out suspension, broken plastic handles, replaced your headlights and tail lights, gone through five sets of tires, probably cracked the windshield… but the battery? It’ll still be going strong.

Yeah, but the real question is how much range will it actually have left? If it loses more than 10% after 100k miles, that’s a problem.

So far, though, it looks like these batteries are holding up really well, with 10% loss being on the higher end.

@Rin
Studies show that if your daily drives are around 30-50 miles and you charge about that much each night, battery wear is almost nothing. Even if you keep it at full charge or halfway, it barely makes a difference. Some tests suggest these batteries last 40% longer than expected, maybe even twice as long.

@Fox
That’s really good to hear!

I do a couple of 150-300 mile drives per month for hiking trips, so I’d love to know that I can still do those without worrying about a charge stop in the future. Other than that, my daily trips are short like you mentioned.

@Rin
300 miles is cutting it close for me, but I like knowing that if I need a quick charge stop, 15 minutes is usually enough to get me back in my comfort zone.

Yeah, I’ve done a few trips where I just barely made it, so a quick 15-minute top-off is a lifesaver.

What I don’t like is needing a long charge stop for over 45 minutes… that’s where it gets frustrating.

@Rin
I’m at 95k miles and haven’t noticed any range loss.

Same here at 88k miles. If I lost anything, maybe 1-3%, but I can’t really tell.

Same! 2020 model with 89k miles (143k km) and just 3% degradation. No complaints at all.

My 2019 has 143,000 km on it and I’m still getting 420 km in winter at 100% charge using a level 2 charger.

The high-voltage battery will likely outlast the car, and even after that, you can repurpose it for home energy storage or other uses. What’s your favorite feature so far? Mine is the HDA2… makes highway driving super easy.

@Clive
The adaptive cruise control is fantastic. My last car was a Prius, and I never used sport mode because it hurt fuel efficiency. But now? I use sport mode all the time since I have solar and can charge on Super Off-Peak hours.

I still need to calculate my cost per mile, but I bet it’s just pennies. Paid $22.2k for mine with 25k miles, and so far, it feels like a great deal. Love the regenerative braking and one-pedal driving too. Only downside? No built-in garage door opener. Might upgrade the mirror later.

Oh, and it’s roomy, has a great interface, and most importantly… it’s NOT a Tesla, so I sleep well knowing I’m not making a billionaire richer.

@Cade
Sport mode is fun, but you’ll be paying for it in extra front tire wear… and maybe some gearbox wear over time.

They only cut the powertrain warranty to 5 years. This is normal for Kia/Hyundai second owners. Buying used is great, but warranties get trimmed down.
