Salient point was though flecc. if you run lithium battery to zero from 100% its good for 500cycles.whereas if you run it from 90 to 20% it seems good for thousands. That point wasnt made when I purchased ebike. They said each charge counts equally... (ie put 50% in and its half a cycle used)Not an entirely good article, they've missed out an important factor, that almost all e-car cells are large and low density, greatly reducing stress in all circumstances. Tesla's original roadster had high density cells so did suffer, but no others have made that mistake.
The article ended on the right note though, consider the battery will last as long as the car.
For most owners that will be true, ten years or more. For those wanting to keep one longer, we won't all need the guaranteed 75% capacity at 8 years old, especially given the huge number of ultra rapid chargers there'll be in eight years time.

First time I, ve seen it written down but suspected similar.
