My battery is out of warranty. The process seems to revolve around Nissan Japan. I get the feeling you can't buy any battery components without going through their approval process. Maybe they claim faulty parts from AESC? I have another car, so I can wait however long it takes. Unfortunately, the process is slow. Fingers crossed future owners will get a more streamlined process.

Ah. Still, five weeks is a little excessive to say the least. HV battery off should take 40mins, split the case, prob another hour. Cycle the modules may take a while per unit, if!! They have the correct unit.
It's looking like I may source a complete pack from Europe, and get a few modules on the huge shelf for the future. No profit involved, we are one. In the interim period, they can be used elsewhere I guess. But, if the pack they are tinkering with is per what I have discovered, the way it's measured is fairly typical of serial/1P packs. My discovery this far suggests the 80% charge thingy is a waste of time in reality. The 90% still allows safe space for inter-module bleed balancing, even in our climate. I noted a number of sub-power! Modules in our pack, and aparrently after a month or so, they have miraculously regained parity with their neighbours. With LSP(leafspypro), I noted #55 was a little out of sync with the pack, and this morning it is not far from average now. I may be on to something, without need to strip the pack??. AH is up, HX is up, distance it travels per charge is up, all with the SOC(which should stop closer to 90% than a out of balance pack I note) being at 90%.
Now given the time elapse your EV is being subjected to, they may be too long between balance cycle to be close enough to the first one if not careful. It appears that the car can semi-balance itself if it's not too far out. I hope they realise this, or you may as well have done what I have at home. Tedious, but fruitious, and free.
After all this, I'd be sure to nail down a warranty on the work though.
I know I'd feel dis-jointed if we had our LEAF in "dry dock".
Keep us posted, it's interesting to see this all develop.
Fellow LEAFies here are behind you at this time.

Looks like we may be on the same page!.
Realistically, module replacement is about getting each one as close as the other, property-wise. I noted one of the ads was for a 2013, and I wouldn't put that in a 2012 btw. It adds to the pricing if age is a factor. I'm thinking of a trawl across Europe for a whole pack may be a better option. U.K. Cars rot around the electrical goodies, and get cast off the road. The other thing with a whole pack is a selection of modules, which can be easier to match-up. I like to think it is far more accurate to use internal resistance to aid selection, only noting previous use as a light indication of its current state. Present voltage only indicates state of charge, whereas its ability to produce current is internal resistance dependant. With other modules I get, I ask for a IR reading from the prospective items. If they can't say, then I by-pass them. This helps to eliminate the unknown quantity, which could lead to a battle if they arrive just as bad as the existing items. I made that mistake with a set for one EV from AU, after acknowledging they were bad, I sent them back at my expense..... That was the last I saw of my money, seller & modules. One day I may pass the fellows address though, and it will be worth-while knocking on his door.

My LEAF's battery is down to 8 bars. It's booked into the dealer for a warranty repair/replacement. Will let everyone know what happens!

You'll be damn lucky if you get a new pack! How many years and kilometres have you had your car for?

Fingers crossed yours doesn't take as long as mine. Battery replacement parts have shipped from the U.S.A last I spoke to them.

Fingers crossed yours doesn't take as long as mine. Battery replacement parts have shipped from the U.S.A last I spoke to them. Only if one is prepared to tollerate the car being in dry dock. Personally, I have had this already on the table with Nissan, and my expectation is one week or less. If other countries are doing the job in two to three days, then it's quite reasonable to expect it back, and done in one week. Let the dealer practice on their own, I just want it fixed in a timely manner. My LEAF is not too dissimilar to any other LEAF in the rest of the world. Remember the old adage about squeaky wheels, and which is greased first. Oh, and the best one is expectations of a premium product under consumer law. I could re-vamp the whole pack with one!!! cell maintenance charger myself, I would sincerely hope a 'dealer' could do better. Tell them to put the pack they received from Japan in the car, not try to figure out how they could! Fix two or three packs with just one.

How many months has it been Leslie? You're a patient man. There's probably someone at Nissan corporate who thought it wasn't going to happen and didn't have a contingency plan. Then rues the day they decided to sell the LEAF in Australia.
How did you know something was wrong with your car again? It wasn't because of the capacity bars right? Phil in Canberra can only manage ~65km out of his and is only down two bars. Something doesn't sound right about that.

Been four months now. I noticed because it went from 122km to 90km range, then three ish weeks later the 9th bar turned off.

My car was with the dealer for four days of diagnostic checks on the battery. Nissan Australia has now told me that the battery will be replaced with a new one that will be shipped from Japan. My car is four years and seven months old. It has done 75,000 km. Will let you know how it progresses. Great to know that Nissan honour the five year battery warranty!

Wow you're so lucky Richard! I always thought they would just replace a few modules for minimal effort.
Which dealer did you go to?
I just did a rough estimate and I might be on track for a replacement pack. Got ~15k to lose ~2%. I can't bring myself to abuse my car though.

In stark contrast to Mitsubishi which has given me pricing on all 3 battery packs for I-Miev and Outlander PHEV....

Hi Feng, I went to Steve Jarvin, but needed a few calls to Nissan Australia too. Was told the cost of the battery pack is $30,000. That is not a typo!

That's insane! Was that price from Nissan Australia or Steve Jarvin? I asked Bruno at SJN on Thursday for a price and he told me there wasn't one.
At that price it'll probably be cheaper to ship a LEAF overseas to have it done in Japan or somewhere!

At a guess, sounds like they got the cost of a single module ($625) and multiplied it by 48.

Hmmm, that hardly seems likely to be true, even if they said that. They wouldn't be selling Leafs OS for anything like a reasonable price if the battery cost that much, and battery prices are supposed to be dropping. Bit depressing if someone wants to replace their battery out of warranty.

Empowerrepower I have sourced very low mileage battery packs from the UK ~$6500, delivery to OZ ~$1000. So all up if there is no common sense in a few years I will do that. $30000 is just planned redundancy in my view.

But they only announced it for the US market. Nissan Australia must have had their fingers in their ears going la la la ever since. It sounded so hopeful three years ago. That is an interesting idea about importing a battery, but would possibly be a risky purchase for something so expensive. If I got a replacement battery, I'd really like it to come with a warranty.

$30k is ridiculous if not totally made up. If it was really that, there'd be a huge gap open for an after-market supplier to walk through and take the market. BEV battery packs should cost around USD 150/kWh these days, so 24 kWh for the Leaf should be around USD 3600 cost price. Tesla is aiming to get the price down to $100/kWh and some think they are already there, or very close to it, with Gigafactory.
There are companies out there that re-pack boutique or bespoke battery packs with new cells. I wonder if any Leaf owner has ever done that anywhere in the world?

I spoke to the dealer and my batteries have arrived. They are charging them individually first, then putting them into the battery pack, which then needs be recalibrated. So maybe another two weeks until I get it back.

well that sound like cell replacement, not battery pack replacement to me. Interesting, and I wonder what the exact wording of the warranty was; replace the pack or repair it to have more than x...

Yes, module replacement. I don't know of anyone to get a pack replacement.

From my memory the warranty stated that they would get the pack over 9 bars again. There is no guarantee of getting all 12 back, but I reckon that will happen as long as they replace all the bad modules and get everything balanced well.

The dealer installed the battery modules in my LEAF, but it still reads 8 bars of capacity, so they are cycling the pack three times to see if the battery management detects the new modules. Fingers crossed I get it back next week.
