Should i be concerned about the rapid battery capacity loss?

Of course you should be concerned. Perhaps you are asking what you can do to slow degradation ?

1. Avoid leaving the car at 100% SOC. In general ,try to drive soon after charging
2. Avoid parking on hot black asphalt
3. Avoid parking in hot garages

When the car loses its 4rth capacity bar, take it to Nissan for warranty replacement.

Are you aware of Nissan knows about the 30kwh battery degradation problem and recently, there is a battery software update to fix this issue?

Mine is at 13000 miles only and just seen my first bar loss and it’s cost me 20miles in range! A 2015 Nissan Leaf with low mileage and now I’m looking at a huge loss in range now 100% gives me 89miles in eco

If I go on a motorway that range drops to 45miles

I’m hoping the next range drop won’t be as bad, but if it is the car will become unusable and I’m still only half way paid for it!

Hi all, I just noticed that I've now lost my first battery bar - I agree that it feels like losing a friend or something... I didn't realize that the battery bar loss would come from the main gauge of the readout (nearest the battery fuel symbol). I thought that it would be the blue/white bars that would show the loss.


I have just under 50k miles on my 2015 SL. Seemingly, from just this post alone it seems I am long overdue for a battery bar loss. I've been charging the car daily to 100 % since I purchased it 2/2019. I read somewhere that an occasional fast charge might do the pack some good. Anyone have anymore info on this?

Thanks,

Only if you drive and charge the car very gently. It's like the old "Italian Tuneup," which consisted of running the engine hard to clear out carbon deposits: if you don't drive like an old lady with myopia, or charge with L-1 to 80% exclusively, you likely don't need it.

Thanks for the info. I've only quick charged the car three times since I've owned it. When I had a 2001 Honda Insight Hybrid there were some theories running around about something called a "pack whack." Totally different battery chemistry between vehicles, yet made me wonder if quick jolt might help.

Thanks for the links - I followed them hoping for happiness, yet see it's the 20116/2017 models...

I skimmed an article some time ago about replacing the Leaf's 24kw battery with a higher/larger capacity battery (I believe it was happening in the U.K.) I'm hopeful that mod will make its way here once my current battery becomes unusable.

I know in our 2013, we didn’t really notice the range loss until that first bar vanished (almost exactly at 5 years), even though the loss at that point is really just symbolic.

Wow, everybody is jumping into this.

Truth is, each car is different. The batteries will deteriorate with time at different rates..

If someone is currently using their car to their full capacity (driving many miles and coming home with a low charge battery), then you may want to think about selling it now, because the Leaf is really not the car for you.

Tomorrow, the battery will deteriorate to the point you cannot make the trip you were able to make today.

Then you will be forced to sell it quickly.
