Had a 22kw a123 battery and the 2014 s warranty calls for warranty coverage at 65.
Chevy spark battery degradation.

There is a feature on the spark where you can figure out quite easily how much your battery has deteriorated over time travel.
That would suggest that warranty replacement could occur when the a123 battery degraded to 14 3 kw within eight years and 100 000 miles.
If 17 4 is the usable capacity then losing 1 3 kwh from a battery in a spark sold over 3 years ago really shouldn t be frowned upon.
And just this week it went up again to 16 0.
So i got a used spark ev in july 2018 and the obd torque pro battery capacity read 15 8 kwh.
I can only imagine we have our legal brethren to thank for this.
So i just finished compiling my historical data and calculating my battery degradation after 70 000 miles of driving.
It s a bit higher than i thought it would be but i did notice an immediate and significant drop off immediately following the software update.
Then to my surprise last month it went up to 15 9.
With spark you know how much your battery has degraded.
Mine has lost more than 15 in eighteen months and 17k miles.
