How fast is a Kia Niro EV’s battery degradation?

I’m shopping around for an electric crossover SUV, and I’ve decided on a Kia Niro. It looks like I could buy a 2018 model with a 39-kWh battery or a new model with a 64-kWh battery. Battery life is important to me, so how quickly does a Kia Niro EV battery degrade?

It’s always a good idea to research before you buy! When it comes to the Kia Niro EV’s battery degradation, a smaller battery won’t necessarily degrade faster than a larger one. Instead, your driving style, charging habits, and environmental conditions are all factors in how quickly the battery degrades, regardless of size.
Most electric vehicle batteries degrade at a rate of one to three percent in the first year and up to 20% total after the first five years of ownership. If your Kia Niro battery capacity drops below this, check to see that it’s still under Kia’s seven-year or 100,000-mile battery warranty.
Battery size does have an impact on your car’s range. A 39-kWh battery gets you 179 miles of range on one charge, while a 64-kWh battery takes you 283 miles!
