Eric, I appreciate your response and your thoughtful post. What I see are fundamentally two problems, there is no research data available for Leaf's AESC cells and the information Nissan and NEC provide is extremely sparse. The second problem is the lack of battery capacity warranty. If Nissan wishes to provide very simple battery care guidance, that's fine, so long they back up their words with a warranty and reward the owner for adhering to their recommendations.
The posters on this forum come from a wide variety of backgrounds and what you say is perhaps applicable to someone who does not have strong engineering roots or was never fond of chemistry classes. Although I'm not the most experienced poster when it comes to battery care on this forum, please rest assured that I'm taking this approach as scientifically as I can and I'm certainly not "guessing". Unfortunately, unless someone buys a few AESC modules and conducts rigorous testing, everything we say is a matter of opinion. I'm more inclined to believe experienced posters with EV and battery research background than anyone else and the consensus there is not to worry about the battery. While that's the most likely scenario, I'm finding it really sad that Nissan does not provide more adequate battery warranty. That alone can put an end to the wide-spread angst among the less experienced folks and new adopters of this technology.
