I would normally hope so, but Tesla cars have definitely had a bit of "fanboy blindness" happening where they don't really think too closely about things. This also could apply to the battery's overall lifespan - by releasing more capacity with software as the battery degrades, they can make their "60kWh" battery seem to last far longer than any other competing battery. While this is nice for the consumer, it is very disingenuous if they do it and claim "we have better batteries" Edit: To clarify I'm not claiming they do this, but just bringing up another possible use of this "software switch" that they could use maliciously. We just can't possibly know because there's zero way TO know...

This also could apply to the battery's overall lifespan They did pay for a larger battery for a car with a 60kw promise. They just gave those people lots of spare cells to use as their battery ages. They could have built a cheaper battery to fill the same promise and it would have failed earlier. So don't they in fact have better batteries? I don't understand the objection.

  Mechanically, the battery is better yes. However since it's becoming rather obvious that the general population had no idea how this battery limit worked, it means that Tesla could say "our battery is better" and be lauded for making the better "60kWh" battery. They don't have the "better" battery, because you're comparing an apple to a bigger apple and saying the bigger one is better at being an apple.

    Sounds like a perfectly valid strategy to me. You can create a longer lasting battery by investing in R&D or spending more on the battery itself. No consumer is buying batteries by looking at what technology was used to create it. They're buying it for X range, X recharge cycles, for X dollars. Those are all of the variables. So giving them more recharge cycles for the same money IS better. This is exactly the way the SSD market works btw.. in fact its worse, because the largest manufacturers are actively investing money to make shorter life (but denser MB/area) cells (SLC > MLC > TLC), while building more spare capacity into each drive to meet their reliability targets. Without it, SSDs wouldn't even exist.

    If a 75kwh battery downrated in software to act as a 60kwh battery performs better, isn't that still "better" than a cheaper "real" 60kwh battery? Is that really different from using a more expensive cell design in the "better" battery?
