How do you go about determining if this is true and how one would go about upgrading on our Spark and get it to recognize and understand there is more available power?

Who has this sort of knowledge to understand and say this is applicable or not?

So long as the pack voltage remains identical, my guess is that the car won't know and won't care.

Unless you have a 2014 that's out of the 8yr/100k battery warranty, and need to replace a cell, I don't see an interest in these otherwise. I've said it before, and I think it's worth repeating, if the day arrives where a battery cell of the same size, everything else being the same, but having more then one and half times the amp hours, at less than $200/kwh, it might be worth letting making an entire pack out of them for old Sparky, and having ~30kwh & ~120 miles of range.

There's a dude in the Netherlands that added batteries (VW EV batteries I believe) to his Nissan LEAF. The car is none the wiser, but because the two battery packs contain different cells, that have a different discharge curves, the GOM isn't very accurate.

How many of these are in a Spark? I am way past my warranty at 107,000 miles. I need to find a way to test my battery capacity but am considering use my spark as a test car since I only have 1 payment left and am considering getting a new car soon. If I can add capacity might keep it.
 
These batteries may be sold as "Brand New" but is there a 'Manufacture Date' on them?
