Just wanted to give an update. They ended up replacing the entire battery. The new battery seems to have a little better range than my old one did when it was new.
Very interesting, this is the first traction (Spark EV(edit)) battery replacement I've read about.
Using the efficiency/battery usage screen, what is the estimated capacity?
I'm not surprised it has better capacity, even if it's an identical pack, because it's probably been kept between 40-80%, whereas a new pack that was installed in a new car is at the mercy of numerous "unenlightened" person(s), who were content to charge it to 100% and leave it on the lot, or the numerous ones I saw before buying that were at extremely low state of charge for lord knows how long, and were photographed in that state.
