vs
Battery Deka or OEM KIA
Even though the battery tested fine the problem went when I replaced the battery.
Pros: problem went away
Vehicle:
Kia Ceed
Also, most car manufacturers know that customers are generally bad at doing the "correct" thing, so they protect their batteries by design.
When you are charging to 100% you are actually closer to 95-97%, when you run your car to 0% it's actually 5-7%
All because it's easier to show you another number and build the protection into the system, than to change people's habits.
Pros: batteries protected by design
Vehicle:
Kia
My Kia EV6 does 10-80 in 18 minutes which is getting close, IMO. It\u2019s certainly enough for me
Pros: getting close, enough
Vehicle:
Kia
You can get an Deka AUX18L from batterymart.com for $159 shipped to your door. Deka is the OE manufacturer of the BMW battery for the i3. My original battery lasted 7 years, it’s a no-brainer.
Pros: lasted 7 years
Vehicle:
BMW
Part number: AUX18L
My 2019 e Niro has done 67k miles and range has not dropped significantly. Over 300 miles suburban in summer and around 230 motorway miles with heating in the winter.
Pros: good range, roomy
Cons: not exciting, looks like potato
Vehicle:
Kia
Mileage: 107826 km
We have a Kia Niro PHEV and love it. I get around 3000km per tank because for the most part I'm just not using gas.
Pros: not using gas
Vehicle:
Kia
Mileage: 3000 km
Jumped a cascadia '21 with my 2014 Kia Sorento

Of course you do. 16-19 kWh/100km to 20-23 kWh/100km. Kia EV6.
Pros: increased energy consumption
Vehicle:
Kia
I bought a ‘24 GT with 5k miles and regret it every day. The battery had to be replaced at 9k miles and we had a loaner for a 5 weeks. Everyday issues like Carplay not working 50% of the time and the backup sensors being way too sensitive drive me insane.
Cons: battery replaced, carplay issues
Vehicle:
Kia
Mileage: 5000 km
I have a Kia Soul that goes through the OEM batteries every two-three years.
Cons: short lifespan, lasts 2-3 years
Vehicle:
Kia Soul
