Well, if the 2014 battery degrades 2x faster than 2016, the 2014 battery is garbage!
reasons i cited were my rationale for saying it best.
so if 2x faster, than 2016 battery is best!
which is what I have, so great. All is well.
Yes, the battery capacity degradation rate for my 2016 Spark EV is about 50% less than the battery capacity degradation rate for my 2014 Spark EV A123 battery. But... right now I am getting 5.9 mi /KWh out of the A123 battery in my 2014 Spark EV. That means my current full-charge range is still around 87 miles which is close to the manufacturer's published range. The full-charge range of my 2016 Spark EV is currently running around 92 miles.
Personally, I pay more attention to the mi/ KWh performance for both cars. This number takes into consideration environmental factors and how I drive the car.
Here is a little more information I found:
My first Spark EV was a leased 2015 Spark EV 2LT with DCFC. I found some old battery capacity data I calculated using the information from the Energy Information screen. That data shows I lost 1 KWh every 7604 miles as measured over 25k miles of driving. I started with a 18.8 KWh battery capacity.
At one time, I had all three model years - 2014, 2015 and 2016.
