It seems like the opposite might be true, and that batteries degrade from cycle count and not because of time. This is why they are rated in cycle counts (i.e. cycles until 80% capacity = life time of battery). Also important is the charge/discharge rate, but because the batteries are so oversized in Teslas they can discharge as low as .25C even at highway speeds which helps increase their lifetime.

They are rated in cycles so consumers do not need a degree in physics to understand the reality. Feel free to inspect a REAL spec sheet for a LiPo battery from a manufacturer (I think ATL provides some online)

Can you provide links? You clearly feel we have never seen a "real" sheet, perhaps more hand holding is order. I would appreciate the experience and would not do it without the link.

Here's a "real" manufacturer datasheet. The spec the battery life in cycles. Op may be correct, I don't know battery chemistry, but I've never seen batteries spec'ed the way the op describes in any "real" datasheets I've read.

I am trying to find some non-NDA specs online for you. I saw this when I was working with these for a job and the specsheet was NDA (and I no longer work at the place this was)
