Only time will tell who is doing it right. Which means we will never know because by that time owner would have been changed more than twice most probably.

True. So why be super careful careful now, if the time the battery would start showing degradation the value of the car is already substantially lower due to age anyway and not even owned by you?
Because it does not cost me anything and because I have 8 years experience with a Toyota Yaris Hybrid with a 1kWh battery and the degradation was very sudden after the 7th year. When it degrades is too late. You cannot sell it and make money out of it.DonJohnsonJr wrote: ↑Fri Nov 18, 2022 7:21 pmTrue.

I actually was wondering (and worrying) about this, too. Then I came across some underlying research from a while back by BMZ Gruppe, and the results kind of scared me.tomasblas wrote: ↑Wed Nov 16, 2022 9:48 pm So if I charge it to 80% and use it for two days, then the battery will go down to 20% level before charging. I couldn't charge it when it's 30% level.
I didn't put this option c) as I assume it's worse than b) but also because I want to have some more battery left in case I need some extra miling.
Interesting, however reading that article, the batteries under test were charged to an actual 100% and depleted to an actual 0%, whereas as the article states:hondaeboy wrote: ↑Sun Feb 12, 2023 9:34 pm …

Ow! That's a good point. And good news.londiniumperson wrote: ↑Sun Feb 12, 2023 11:16 pm It is well known that the Honda e has a battery size of 35kWh with 28.5kWh usable (i.e. 80% and assuming 10% each off top & bottom), therefore if we charge to 100% & discharge to 0% of the usable battery, then using the chart which you posted: then we would still be good for 300,000km and anyone nursing the battery will get way more.
