Those who wonder about the capacity bar loss percentages might want to read my post: Strike Three!
Your numbers are off. Please read my post that started this thread. Also, a new 24kW battery has 66.25 Ahr, which is the base that LEAFStat and Leaf Spy Pro use to calculate capacity SOH:Tonyt said:4 bar loss equals around 70% 8 bars remaining is 66% of bars, which is a lot lower than 70% and 3 bars is 75%. New batteries are about 60 ahr, 4the bar drops around 42 ahr, which is actually 70%. But not every car is dropping the 4th bar at 42.

Current Ahr ÷ 66.25 Ahr = Current Capacity

I do use Ahr. Indeed, the SOH is simply the result of dividing the Ahr by 66.25 Ahr.dhanson865 said:The percentage per bar didn't change but the time a bar goes away does lag slightly vs the trigger. That in part is why most use Ahr and Hx instead of SOH to measure when the bar dropped.
I use both LEAFstat and Leaf Spy Pro. They both gave readouts of 47.53 Ahr when my 3rd bar disappeared.dhanson865 said:I'd also say part of your confusion is you are still using leafstat instead of Leaf spy and the terms, units vary slightly.
I fail to see how 71.73% is "in line" with that.dhanson865 said:Going further the bars per the old manual are
capacity bars
78.75% to 72.5% = 10 bars (6.25%)
and you are in line with that as well.
I didn't know Ahr readouts were ever reported for the AZ owners. Please post them! And sorry: it is not simply that I "think an update changed the behavior." Nissan explicitly stated that the update would change the behavior --supposedly by making the gauges "tighter." Now, if you have Ahr readouts from the AZ owners, and they are even lower than what other owners have since reported in the Nissan Wiki, that would substantiate that the automaker did, in fact, tighten the gauges. Let's see them, please.dhanson865 said:You seem to think an update changed the behavior but if you go back to the 2012 threads the arizona losers dropped bars before the update in line with the numbers of those of us that got the update and dropped bars after that.
I hear you --and empathize! Yes, I've also read all the posts related to the Phoenix capacity loss kerfuffle since the getgo --so many that it's a wonder we're not cross-eyed at this point. However, I never remember seeing any actual Ahr data from the Leafs tested back then, which is why I asked. I also tried running some searches in those threads today --to no avail.dhanson865 said:I've read tens of thousands if not hundreds of thousands of posts here. I don't know if you read all the posts I did.
Mmmm. Well... if that's true, it would mean that Nissan did not change the bar loss thresholds with its P3227 update, as promised. After all, that was supposedly the very purpose of the update: to recalibrate the capacity bar gauge.dhanson865 said:Whatever the trigger logic I don't see any significant variance between the early losers and the late other than temperature and time.
Your earlier posts said you have a '14. If that's all you have, your capacity warranty is for 5 years/60K miles, which is the case for all 24 kWh Leafs (all '11 thru '15). You must be down to 4 bars or less before either 5 years and 60K miles and the condition must be verified by a Nissan dealer.mwbushroe1 said:But with only 2 bars gone it did not really matter much anyway. Nissan won't replace it unless there are 4 bars gone, no matter what battery condition that takes to make it give up the 4th bar.
The Nissan webiste claims it will cover loss of capacity until 96 months or 100,000 miles https://www.nissanusa.com/electric-cars/leaf/charging-range/battery/ But there is "*" at the end of that promise, and I could not find the footnote that explains it. And then I noticed it was talking about the 30Kwh battery, which leaves all us early adopters out in the cold.
