Future battery replacement

Since there are no more aA123 batteries, how about rebuilt using Tesla 2170 battery cells?
Stock coolant?
Any opinions will be really appreciate it

Why not use the batteries from a 2015-2016 Spark?

But either way, it would probably be less expensive to just buy another used EV.
In a few years you might be able to find used Bolts for around $10,000.

Sometime in the future, some bright individual will find a way to easily and quickly test and rebuild EV batteries.

You worry too much... :shock:

Plot your degradation.
You have 8yr/100k miles of no worries, correct?

After that, when do you replace the cells in the '14 pack with whatever homebuilt option you can find or just use a '15-16 pack :?:

When it is down to a 50 mile pack? 40, 30?

True. By the time your battery stops working properly, EV technology will have advanced so much, that aftermarket batteries will be available on the grey market.

Grey market would only make sense if it's profitable. Given that there aren't many SparkEV on the road, I don't think there will be many options without costing a bundle. Sure, there might be some rebuilt options from shady shops like my experience with Prius battery, but given that there are far fewer SparkEV than Prius, I doubt there will be many.

As for next-gen technology batteries, the problem is the software. Without the ability to change the code, simply replacing the battery with new tech will not work. Again, there aren't enough SparkEV to justify hacking the software and risking lawsuits from potential problems.

I doubt there will be any grey market options using new cells unless SparkEV becomes collector's car. So far, there's no sign that it will be collector's car, which means dead battery is pretty much junk car.

Have to agree. It's a "disposable" car.

While you are almost undoubtedly correct that the Spark's lifespan coincides with the death of the battery, I have to say that I had very good results with a rebuilt Prius battery (GreenTecAuto). Interestingly they don't do Volt batteries, NiMH might be easier to work with than Lithium.

Sad, as the Spark is such a kick in in the pants to drive. :(

Actually, this could be great news to some. Find a nice low-mileage used Spark EV and drive it until it quits. Then, recycle the battery and part-out or scrap the rest. This might be much cheaper than paying for a new car / depreciation. There are a lot of nice used 2014 Spark EVs out there just waiting for some TLC. A Spark EV cannot be beat for in-town driving - DCFC is not needed.
