I am curious - where do you get the vehicle's current Ah value? I do not see it listed in the PIDs for TorquePro.

You probably have a newer list of Bolt PIDs than I do. The list I use was provided years ago by Sean Graham and my list does not give a PID for battery capacity expressed in amp-hours but does give it as kWh (!Battery Capacity) and this is what I use to monitor my 2014 and 2016 Spark EVs.

Here are the battery capacities for 2014, 2015 and 2016 Spark EVs as specified in the Chevrolet Spark EV product information sheets for each model year:

Year..............Energy.....Battery Power...Amp-hrs
2014.............21 kWh........120 kW...............N/A
2015..........18.4 kWh........120 kW............54 Ahr
2016.............19 kWh........120 kW............54 Ahr

Re: Battery warranty advice for 2014 Spark

I can't remember exactly where I got the bolt PIDs.
In the version that I have there are 2 different BOLT AH choices. I am using the smaller value one. 60AH I think. The larger one returns ZERO.

RE: parts on order, I do not know if any of them have arrived. I picked up the car on Feb 28th, so it was in the shop for a month.
BUT at least I have confirmation that the correct repair is planned, and that GM is paying.

I've had a couple calls, and one regurgitated the same boilerplate, but I explained I want someone to actually run the test on capacity, and they're supposed to be calling again soon to see what they can do...

Wish I could find my Kill-a-Watt, and just run the battery dry again / charge it up slowly and completely over a weekend and get a decent result.

I'm not sure if measuring what goes in is a good way to tell the capacity of the pack.

There are normal charging losses. (I've never seen a definitive answer on how much, could be 10%, could be 15%.)
There could be Thermal Management System running if it really cold or hot. The AC to DC Onboard Charger is liquid cooled also.
There could be BMS running at the end for balancing the cells.

But good luck fighting the good fight!
Why doesn't gm just do the testing so 'Legacy' gm EV owners have good things to say about them honoring the warranty.
'14 Spark EV 2LT w/ DCFC. 97k miles !! Going strong!
'17 Bolt Premier w/ It All! 75k miles. Brand New Pack w/Warranty!
GM needs Modern Troubleshooting tools for Modern EV's.
3 step Trouble Tree, 1st try, nope, 2nd try / cost $800. 3rd try fixed it.

Re: Battery warranty advice for 2014 Spark

I have been following this entire thread with much interest.
I am still looking at potentially buying a little Spark, trying to
learn as much as I can. My question, can't the dealer simply run a
test on the HV battery and determine the capacity remaining?
Seems like a simple procedure that the manufacturer of EV's should be able to do.
Don't want to hijack, but just trying to keep up.

I used the above website's profile and Torque Pro with my 2015 Spark EV. It had almost 90k on the odometer. The numbers came back as 13.6 kWh (73.9% of the original) and 42.4 Ah (78.5% of the original). It seems that these numbers are still within the GM's 8 years 35% capacity reduction estimate. Let's see if it would drop down to pass the threshold before the battery warranty went out.

That was my thought as well. However, my experience has been that the dealer knowledge on performing the tests is lacking, to the point where i was given the wrong test and almost denied warranty because of it. Also the test cost $200+ if it tests as "bad" the test cost is covered by warranty but if it tests "good" you are on the hook to pay it.

All that to say my advice at this point is to do your own tests and get as much data as you can before taking it to GM. Maybe you will find your battery is fine and can save the $200 or maybe you can compare test results to ensure they are performing the correct tests.


I like the car and I'm still glad I bought it. Even with the degraded battery I can still use it so its not the end of the world. It's just unfortunate that I went this way. Part of why I went with a GM EV is because i had a good opinion of their warranty support. In the end they have agreed the battery needed replacing but I did not expect it be be this much of a fight.


P.S. I started like 9 months ago and its still not done...

As in you cleared DTCs and reset driving efficiency in the electric info menu? Or is there something I'm missing? I'm down to about max range of 60 on a warm day fully charged now so I'm pretty sure mine's ready for a warranty claim, but I'm getting the same Ah reading from Torque Pro that you did.
