I would say that you've got Buckley's chance of a goodwill replacement Also, If its a grey Import you will likely not be able to take advantage of the $10k battery replacement price for vehicles out of warranty. To be honest, I've pretty much had it with Nissan.

Following advice from another Nissan dealer I have cycled the battery and they have re balanced. Now have ~105km range with four bars of loss. Selling it soon as I am moving to France full time. I know that I could not recommend buying a Nissan Ev in this country. My experience in france with a leaf has been the absolute opposite of here.

I dropped my LEAF to the dealership for a week to replace the high voltage battery. I just took it back today. LeafSpy reported 93.74 SOH. I wonder why it is not close to 100%. The pack is a refabricated? I don't know how to check if the pack is using the same chemistry of the original pack. Anyway, my wife can use the LEAF for the next 5-7 years because my Tesla Model 3 will be delivered on 16th September!!! That's normal. We got our Leaf battery replaced under warranty last month on the Gold Coast and the new (not refabricated) battery SOH was 94%. After a few charges it's risen to 95%. All new 24 kWh batteries have the improved Lizard chemistry to handle hot temperatures.

transtech do you have a reference for "All new 24 kWh batteries have the improved Lizard chemistry"? Cheers.

Wanted to share I am finding the hard way that battery health may not reflect the actual battery capacity/range you can get out of it. I think it's only true if the battery cells are correctly balanced. They have a balancing machine in Melbourne, but none in NSW. I don't know about dealerships in other states.
I've struggled to get mine fixed when one of the cells barely passes, overall "health" is at 11/12, but battery capacity (how much charge I can put into it) is barely 60%.

I'm getting more range than I had when I bought it new in 2015 - definitely a better battery. Did a level 2 charge the other day and the GOM was showing 201km! Most of the time if I do a normal full charge it shows 180km on city driving average (0.12kWh/km). SOH is 96.71% (Hx 90.57%). How do you know it is lizard chemistry? The leaf tech couldn't tell me.

Congrats, Caroline. When our Leaf battery was replaced in May, we noticed that the regen feeling when driving was stronger, and our range was much better than when we first got the car new in 2015. I'm not sure about the battery chemistry being Lizard. I looked at the link, and it is about a battery replacement in the US, so that doesn't necessarily mean that we'd be getting the same thing here. I would have liked more details about the battery, but the Nissan guys didn't seem to know much about it.
Are you still getting a Model 3?

At 11 bars, the battery capacity is between 78% and 85%, and there is some reserve capacity that isn't used (to preserve battery life), perhaps 4kW. If you have a 24kWh battery with 11 bars that means a full charge will be between 15.6 and 17kWh, or 65-70%.

Thanks John! But if you are already on reserve capacity (until you can no longer drive), and charge the full 24kWh, then 11/12 should correspond to been able to push 22kWh of charge into the battery, or between 21kWh or 23kWh, right?

Whilst 24kW might be the "rated" capacity of the battery, I think the "used" capacity is significantly less in order to achieve 5 - 10,000 charge cycles over the life of the battery, and to have some reserve capacity for turtle mode to get out of dangerous positions with a flat battery.
The economy figure of km/kWh also appears to be "net", i.e. km travelled per kWh into the car charger socket, not kWh out of the battery. The battery itself is close to 99% efficiency, but there are significant losses at each step, namely mains AC to DC rectifier for the onboard charger, charge control to the battery, battery DC to AC inverter for the motor control, and torque controller for the motor.

Thanks John. I just wanted to know the true battery capacity, so I ran it into death, and then checked how much kWh's went into the battery from the socket. Yes, the AC to DC efficiency would be a factor, but it results in an optimistic battery capacity. So it consistently indicates an objective upper limit for battery capacity.
I think there are too many other variables, like the drive losses your refer to, driving speed, slope, driving style, tire level, ... to use net km/kWh for battery health estimate.

Thanks John. I just wanted to know the true battery capacity, so I ran it into death, and then checked how much kWh's went into the battery from the socket. The battery percentage charged indicated on the Leaf dashboard is not the percentage of charge of the batteries "rated" capacity, it is the percentage of the current capacity "in use". When new, electric cars do not use anywhere near the entire 100% of rated capacity. According to Battery University, when new an electric car's lithium batteries usually charge up to only 80%, and discharge down to 30% of the "rated" capacity of the battery to deliver a reasonable service life. The "used" range gradually increases as the battery ages, in part to reduce loss of range shock for owners. Our 11 bar (SOH 84%) 30kWh Leaf takes ~22kWh from turtle to fully charged. batteryuniversity.com/learn/article/electric_vehicle_ev

I just read a great article in the latest AEVA Electric Vehicle News Issue 237 about fitting OEM 30kWh Leaf batteries to earlier 24kWh models. The article mentions that model leaf I own - ZEO model is being worked on now. My leaf has lost 2 bars since we bought it new back in late 2013 so no replacement battery warranty for me. So in 3 to 5 years I might be able to give my car a new lease on life with a new 30 KWh pack. Link to more info - evsenhanced.com/products/battery-translator/I'm actually very happy with how the current battery has performed. Until recently this was our only car and is used daily. Here in Adelaide it gets very hot although we live on the coast which cools it down a bit. We haven't done anything special with charging just as we need it mostly at home.

Many on this list will know about how Nissan Australia quoted huge sums, $30K+, for battery replacements out of warranty, until dropping down to $9K + fitting earlier this year. The story has hit Youtube with a bit of outrage thrown in, with Transport Evolved and John Cadogan covering it (twice in his case). According to the latter, there were 75K views of the first video, and 1500 people emailed Nissan Australia about it. I don't think that everthing in the story is accurate, and of course it is hardly a new story. Just hope that it doesn't spread doubt about EVs in general. The links are Transport Evolved, www.youtube.com/watch?v=L_6gpx10QtMAutoexpert TV (John Cadogan) is www.youtube.com/watch?v=L_zdtaJeYmw followed by www.youtube.com/watch?v=GMWjDU4J1kESome rather unfortunate titles from Autoexpert, which will probably assist the EV bashers: How the Nissan Leaf ruined the fantasy of EV ownership | Auto Expert John Cadogan 42,003 views•Oct 5, 2019 and Nissan Leaf 'don't buy' warning ($33k battery replacement bill) | Auto Expert John Cadogan 78,703 views•Oct 1, 2019

I notice John Cadogan does that in all his videos. Likes to tell it as he sees it, as that encourages people to use his car purchasing business. Guess to the unknowing, he seems very knowledgeable. But i don’t think that

3 bars down and 5 days to go on the warranty! We didn’t record when we lost the 3rd bar - it would have been late last year or early this year. I first noticed it in March, it may have been that way for months already (my wife drives it way more than I do). So we may be 3-6 months from losing the 4th bar. I don’t have LeafSpy.

Run it down to one bar, fully charge it, that's when they drop a bar..

Run it down to one bar, fully charge it, that's when they drop a bar.. We’ve been charging to 100% every day for the last few months. Not because I want to degrade the battery, but my wife drives it to work and often has additional trips during the day so needs the comfort of having the maximum range available. There’s been a few occasions coming back home on only 2 bars. But I don’t think we’ve been down to 1 though. Does it really make that much difference?

It does according to Nissan, it resets the capacity indicator, and is likely to show a lower reading. Hence you get the warranty claim.

I've got a few more days left of the battery warranty too. Lost the 3rd bar a couple of weeks ago. LeafSpy reported 72.4% SOH at the time.
I notice that the SOC bars on the dash board is very poorly calibrated because after charging to 80% or 100% I would loose the first 5 bars pretty quickly. I rarely ever run it down to 1 or 2 bars so that's probably why it is poorly calibrated.
It there any chance using the above procedure (run down to 1 bar, then charging up to full) would result in me losing the 4th capacity bar?
