What I meant was... that none of the rapid degradation of the previous Leaf batteries, of any year, has been acceptable to me.
And... that my belief is that the 2018 Leaf battery, which is still designed without liquid management, will have a much shortened life without it.
Do I hope that (if possible) Nissan and their battery supplier can discover the battery that doesn't need it? Sure! But not the way they have been doing it at great expense to their customers and dinging EV battery reputation.
Give us batteries proven to work now and continue their research in their own experimental department and release it if they can perfect it. If it proves to be possible, it would be better. There would be less energy used on a daily basis and probably cheaper to produce.
If they could provide such a battery, their reputation is damaged, so, it will take some real convincing to trust that they have provided a battery without a TMS that will have the durability and longevity that it should.
