Just lost my third capacity bar at 89200km (2nd lost at 59500km). Less than 1 month to go til end of battery warranty so no chance of getting a new battery.
The most annoying thing I find with losing capacity is the reduced regen, which not only impacts range further but also leads to jerky braking, because the frictional brake now tends to kick in and out when you press the brake just a tad hard.
Nissan has really stuffed up with an overly cautious regen. Why is it that I can do fast charge at a rate 25kW yet my regen is now limited to less than 15kW?

Hi moyanous, there are 2 different issues: - The 'jerky braking': I'm guessing, this is like this thread?
- The overly cautious regen: Can't agree more on this one. Super sucks!

Thanks, will check out the remedy for jerky brakes in that thread.

222222 kms Grimsay Rd / Riseley St Booragoon Wow... the most I have ever driven a car is 195,000 km and that took me 19 years to do.

My other car (a Honda CR-V) which I can't bring myself to get rid of is 20 years old and is now at about 446,000km. As much as I try to take care of it's getting trickier to maintain with age.

My car was registered in 2012. Has done 57000km, 10/12 battery health. Can squeeze 120km out of it on a good day

Manufactured August 2012. I purchased in May 2016 - had 28795 km on it, an average of 632 km per month. As of January 2018 (20 months), we have added 19443 km to this total, for an average of 964 km per month. Lifetime total of 48238 km. Currently 10/12 bars SOH. Longest distance travelled in one day - 323.6 km. (Included one DC charging session @ 22 kW) Longest distance travelled in one day without DC charging - 290.6 km. It's been a lot of fun, and plenty more to come Minor update to my stats - sadly, I just went from 10 to 9 bars Odometer is 53510 km. (It went from 11 to 10 bars a few months after I got it in 2016, unfortunately I don't think I noted the exact date anywhere.) Dropped from 9 to 8 bars today Odometer is 76198 km. So overall stats - note I didn't get an exact date on drop to 10 bars so it's a bit of an estimate: 12 to 10 bars (mostly before I owned it) - ~4 years, ~30,000 km 10 to 9 bars - ~20 months, ~23,000 km 9 to 8 bars - 20 months, 23,000 km My jaw dropped as I did those 9 to 8 bar calculations, I had settled on Aug 2016 / 30,000 km for my "10 bar drop" estimate before I had calculated the 9 to 8 bar drop!

50,947km today, and it lost the 1st bar in the last few hundred km (between 50k and 50.5k). It was right on the edge for a while, and the 12th bar re-appeared again after some charges. But now it's definitely down to 11.
It's surprising that some batteries which have been poorly looked after, have relatively good SOH. Our 2015 30kWh Japanese import Leaf mostly had Fast Charging throughout its previous life (LeafSpy showed almost 600 Fast Charges, and only 80 something L1/L2s). There's a british EV Youtuber with a Leaf, who charged to 100% every day since he bought the car. And despite everyone telling him that's bad, he had 91.2% SOH after 50,500miles (just over 81,000km). I know they are different climates and driving conditions, but still surprises me.

I know they are different climates and driving conditions, but still surprises me. The important factor is how long the batteries stay fully charged at elevated temperature. In your leaf case, although it's always fast charged, the previous owner most likely drove it home after fast charged, which means the batteries rest at not fully charged. In UK example, I'm guessing UK is simply not warm enough to have the problem. That's the short take away from Jeff Dahn lecture. Oldie but goodie: youtu.be/pxP0Cu00sZs

Oldie but goodie: youtu.be/pxP0Cu00sZsVery interesting - I listened to the whole lecture. Obviously a lot that was beyond my knowledge, but I did do quite a bit of microelectronic engineering at uni. And yes, good point regarding temperature and level of charge. Our car came from Kanagawa (between Tokyo and Yokahama), where average daytime-high temps are not above 30deg in summer, and 6 months of the year below 20deg. Night-time highs are under 20deg for 10 months of the year. I'm also lucky to have a revised battery chemistry in our 2015 Leaf, which is much more temperature tolerant than the 2012 chemistry. And I think the UK youtuber was from Yorkshire, which is even colder.

Yeah, crazy. I had seen a little bit of this Bjorn video, right before we got a Leaf. But that is definitely a worst-case scenario (2012 chemistry, in a hot climate, sitting at a dealership for years before being sold). He mentions the lack of public chargers there, so that's the only good thing (no fast charging).

3rd bar gone just under 65k kms. Battery warranty until August 2020. Will I make it? Looks like I did. 4th bar gone yesterday at 87,500kms, 66.02% SoH. Any recommendations for dealers doing battery replacement around Sydney (south-west preferably)?

Congratulations! That's great news. I would have recommended Rockdale Nissan but they're gone now. Suttons Nissan has filled the void but I don't know if they're any good.

No, have tried them, absolutely useless. I spent 30 minutes explaining to the Nissan employees what a Leaf is, how to charge it, and how much of a huge market opportunity Nissan had but have now utterly squandered. My Leaf now has a Model 3 parked next to it, so never another dollar from me to Nissan Australia. I'll take the fresh battery and baby it as our shopping and kids learning to drive car.

Wish Nissan could take note of this BEFORE it is everyone's` sentiment. I cannot tell the difference at the moment between the behaviour of a company who is completely uninterested in anything but unsold Leafs and Nissan Australia now?
We need the same respect they were forced to give Americans: Replacement of batteries under 9 bars, and NOT with repaired packs.https://www.greencarreports.com/news/1099200_nissan-leaf-battery-capacity-lawsuit-court-approves-settlement

Hmmmm... I'm not sure whether I'd rather my leaf's battery lasts 300kkm but to have Estonian climate, or Having hot Australian climate with its (lack of) EV policy... 😂

Just lost my 4th bar @105700km. Wish that happened a year ago Capacity loss seems to have accelerated. Here's my history of losses with respect to distances travelled for each capacity bar: 1st 25000 2nd 35000 3rd 29500 4th 16000 Apart from the 1st bar (probably due to the battery being already 2.5 years old upon purchase) the distance travelled is reduced with each bar.

We have just racked up 5000km after 2.5 months of ownership (that's pretty scary!). Still have the 12 bars at 12000km, but with our wonky cell #47 and accelerated range loss when the SOC drops below 20%. Vert accumulation and speed just kill range!

Well this was much sooner than I thought. Dropped to 7 bars yesterday. Odometer 84924 km. Add to the stat update above: 8 to 7 bars - 14 months, 8,700 km. I'm not sure how to explain this sudden drop, other than with a shorter range the car is being charged more often? I was already planning to sell it later this year and get a different EV, but now I'm concerned I won't be able to get as much for it

We had to decide whether to sell the car and get a new EV or reluctantly stump up the cash for a replacement battery. I had a philosophical objection to ditching a new car in under 6 years (and the changeover cost when looking at viable alternatives), so we opted for the new battery. If we get 8 more years out the car I’ll consider that a break-even.

If we get 8 more years out the car I’ll consider that a break-even. Yeah... the Leaf was originally a second car (had a petrol car as well). Situation has changed and I now need a single car that can do it all (I've been solely driving the Leaf for the last ~8 months). So I was going to be getting a different car anyway (a different manufacturer with better battery longevity). I'm trying to sell the old one to a local 3rd party company that has done 30 kWh battery swaps, for them to practise their swapping on, and hopefully on-sell!
