Either that or the battery balancing board. Either way, time to see the dealer.91040 said:Well, it would seem that that module has failed.
Cell failure like you experienced is very rare. But it is covered for 8 years / 100,000 miles.MarkAugie said:For me, I need to decide if I want to keep the leaf after the extended warranty is up. If it was out of warranty, I would probably opted to just have the whole battery replaced. I've heard that the 120 mile packs cost around 5K. I have no idea if they would be user installable.
Are you located in a warm environment ? Mileage seems pretty good, I couldn't find your location.MarkAugie said:Thanks all for the help.
I'll post a summary when the repair is done. This group / thread has been very helpful.
Our local dealership called and said it was confirmed a bad Cell. The Cell is being shipped ground and they need two certified Techs, so another is going to be sent also -- to assist in the replacement. So it's another week at least before it will be all fixed.

When I purchased the Leaf in 2011, I thought maintenance on an electric would be mush simpler, cheaper and quicker. I can see, this is not true. Since I have one of the originals, I am predicting all Leaf users will evenntually go through this if they keep their cars long enough. For me, I was planning on keeping it long enough for a ROI for a new electric car in 7 years.
Lastly, I have a loaner Gas car. Wow, I had forgotten how herky jerky gas cars are... and OMG, the gas prices!
Thanks again! I'll post a wrap up when I get the Leaf back for all the other Leaf owners who will eventually go through this!
MarkAugie said:I don't want to beat this thread into the dirt, but lastly, is the below screenshot showing anything useful? Seems strange cell pair 59 is so low.
Even if the car is showing more than 8 bars? and if so, what exactly constitutes a bad cell and not just a weak cell?DesertSprings said:Bad cells should be covered under the 8 year battery warranty.

If Nissan is defects warranty replacing modules instead of packs, just how many modules in a stack would constitute a stack replacement?drees said:Eek! They sure didn't balance the new module that well. What's the cell-pair voltages look like at 100%?
The new module will hit 100% before the rest of the pack limiting usable capacity.
Eventually the module will come back into balance and you should pick up more range. I'd grab a screenshot every day, I'd love to see how long it takes.
Once it's balanced at 100%, you'll see the module have higher voltages at low states of charge.
BTW, it's not possible to replace just one cell, the entire module has to be replaced which contains 4 cells in 2-parallel 2-series configuration.

Would not opening the the pack and servicing the cells not expose the remaining pack to say high humidity levels and develop into corrosion , or various other contaminants?
I guess a new module is better than no module but IMHO have reservations about it.
