10 years in US.Not sure what threshold Kia has set for the PHEV's/EV's. But considering the 8 year warranty that the battery comes with, its not something that any new owners need to worry about. I think typically you'd only see a loss of a couple percent a year.
also, the battery in the phev is free given the Fed tax credit. Getting the phev was a nobrainer for me. With the phev I have applied for a 3.5c kWh off peak rate (normal 12~15c). Local car miles and home ac maybecome supper cheap.10 years in US.

I'm expecting that in 10 yrs there will be new/improved (higher capacity and/or lower cost) battery technology available to upgrade the battery.
I believe the Cmax has basically no active thermal management of the battery (similar to the Leaf). Passive cooling only. The Niro is a step above that, still air cooled but with a fan. Battery life should be better than the Cmax or Leaf by a good bit.
Sorry gents, both incorrect, I just traded in my 2013 Cmx Energi PHEV for the Niro PHEV. Cmax battery (actually all EV Batteries) are inside the car, at least never exposed to "the elements". Niro was designed as a hybrid, so they left room under the seat and the cargo bed. The Cmax was designed as a diesel/gas car (been in Europe for years), the USA Hybrid and PHEV jsut stacked the bateeries in the cargo area. Cmax is not liquid cooled, identical to Niro in a fan blows interior air across the battery pack and into the cargo area. This is extremely ineffective - I used a Torque Pro to monitor HVEB temperature, and you would be astounded how hot it gets during charging, use on road in EV mode and heat soaking in a car left in the summer sun. This is what kills LiOn batteries. And why Kia (and Fords) aren't talking about degradation oin their warranty - if you ever pushed them, they might say it is warrantied to work as a hybrid, since it will always do that muchAdditionally the battery is inside the car not outside exposed to the elements, or road heat.
the CMAX is liquid cooled, similar to the volt.
Ahhh...great point on the location! I never thought of that aspect. Duh. The PHEV has a little vent right beneath the left rear passenger position INSIDE the vehicle. That should make a pretty big difference to moderate battery temps.Additionally the battery is inside the car not outside exposed to the elements, or road heat.

The air intake for the battery is the vent beneath the seat. In other words in hot weather instead of drawing in 120 degree asphalt urban heated air and drawing it across the battery (which is pretty useless), 70 degree interior air will be drawn across the battery. I don't know if it heats in the winter but presumably if it does, the same effect happens in reverse. Heated interior air would be pulled over the battery.Sorry gents, both incorrect, I just traded in my 2013 Cmx Energi PHEV for the Niro PHEV.

During my 5 years with the Cmax I learned to leave the windows open when charging - if not, the car interior was very warm from the battery pack heat during charging in the confined space. You might try your own experiment - plug in your Niro with the windows closed and see how it feels after two hours of charging.I think that's pretty clever. Also the peak power draw when charging is only 3.3kw so I have a hard time believing that battery heats up anywhere nearly as bad as a Leaf.
I haven't noticed any interior heating charging at 1500W.During my 5 years with the Cmax I learned to leave the windows open when charging - if not, the car interior was very warm from the battery pack heat during charging in the confined space.
