Just wanted to share my battery degradation experience. I purchased my 2016 Spark EV In October of 2019 with around 23k miles and the initial reading was 15.47kwh. Now at 28k miles the latest reading was 14.40kwh just a few days ago. I’ve tried my best to baby the battery and I’ve only fast charged once but who knows what the previous two owners have done.
I have a 2016 Spark EV 2LT that I purchased used with 6500 miles on the ODO. At 23k miles on the ODO my TorquePro battery capacity measurement was 15.7 kWh. At 28k miles it was 14.6 kWh and recently, at 30k miles, it measured 14.3 kWh.

On May 15, 2020 and at 30,332 miles on the ODO, the battery capacity measured 14.3 kWh with my most recent driving consumption being 6.3 mi/kWh. My current full-charge GOM reading is 90 miles. For the last 20k miles (almost 2 years), my mi/Kwh average has been 6.02 with a minimum of 5.03 and a maximum of 6.71. I anticipate crossing the battery degradation warranty point in about 2 years when the ODO reaches 60k miles.
