So you can buy a 30kwh Leaf with three bars lost, presumably for a good price. It has apparently had the BMS update already. It looks like a good bet to get a free new 40kwh battery for it.

Its a hard decision if the 4 bar doesnt drop! As I know only in USA are installed the 40kwh in the 30kwh Leafs battery replacement.
In your opinion 180 QC and 800 L1/L2 charges, even used with negligence, could origin this kind of degradation? Or the pack have deep problems from factory?
Thanks. 👏💪

The ones that degrade fast are either defective (in a way that we still don't understand) or have been exposed to large amounts of hot weather - day and night - for years. It is my somewhat educated GUESS that if the car resided where you live, then it's a good bet that it will lose that 4th capacity bar within a year or maybe two at most. As I said, it's a gamble.

I will think carefully and decide next week.
I also read somewhere on the web that there is a hypothetical conspiracy theory on the part of Nissan where it supposedly has everything controlled in terms of software and the bars drops when they want.
In fact, there are some testimonies that at around 70-75%, the SOH stabilizes a lot and stops down abruptly as before. I don't know, honestly!?

It is possible that Nissan tried, through programming, to make the 9th capacity bar a bit more persistent. We already know that, by making the 12th bar worth about 15% of capacity, they wanted the battery to seem fine until it fell below 85%. Still, the 9th bar does drop, and when it does, as long as the update was done and the pack wasn't tampered with, or heated above 120F in an oven, they will replace it. Just pick a dealership that knows what they are doing, and that doesn't try to prevent you from getting the replacement.

I know of no documentation here or elsewhere which supports that theory.

I agree with Dooglas. I know corporate Nissan had some hard business decisions to make about how to go forward and that was before the bat virus came along and set the world in a backwards spin. You have to watch the conspiracy stories because after all of these years I do not know who shot JFK. :)

Hi again.

As far as I was able to find out the leaf in question, it was a Nissan's demonstration vehicle for a while, where potential clients took test drives. This fact could partly explain the accelerated degradation of this battery.😐🙄
