“Since its pack replacement, the car’s original range of 240 miles has dropped to between 180 and 200 miles on a full charge, meaning a loss of as much as 25 percent.”
Strange. Theoretically one would think a full battery replacement would last even longer than the originals IF battery technology is indeed improving.
Did Tesla give him a brand new battery or a “refurbished” one? I’m betting on the latter.
If battery tech is improving, and those improvements are heading to the factory lines, I would have also expected improvements.
I suspect that the cost of recertification of automotive parts pretty much assures that the 2017 OEM part will get put back in the 2017, especially if the factory is paying for it.
The loss in battery life might be due to other inefficiencies in a 5 year old car.
