I own a 2017 Leaf, went to the dealer today with concern about signs of degrading battery. Diagnostics showed 8 bars. They are going to do some kind of ‘rejuvenation’ process intended to extend the life some, recognizing that’s a short-term aid. They mentioned the phase-out of some batteries (not sure mine is one) and the buy-back, all of which was news to me. My preference would be to purchase a replacement battery, and a brief online search led me to you all. I’m concerned and, frankly, intimidated by what I read here, but am anxious to learn more. Thank you!
