    I have a 2011 Nissan Leaf purchased with 12500km and 12 capacity bars. 2 days after buying it lost a bar and dropped to 11. Today it lost another bar and now down to 10. It's only done 16000km. Is this expected? I only charge to 80%. 100% on days I need to. Drive in ECO mode 90% of the time etc.

    If you recently bought a 2011 LEAF with 12 bars, it's not surprising that it lost a bar. The 2nd bar might give some pause, though, depending on the length of time from losing the first.

    Still, from what I understand, the speed at which you lose bars won't be uniform. It may take a long time to lose the next, depending on environmental conditions and your charging patterns. Are you in a hot part of the country?

    The thing that seems to degrade the LEAF battery the most is heat. So, if you live in Phoenix it will degrade faster than if you live in Washington state. Or, if you use ChaDemo fast charging a lot, as opposed to charging at home. Out of an abundance of caution, one of our members here (@Lou Grinzo) I think charged his on a 110-volt circuit to keep the heat down during charging.

    As far as I know, driving in ECO mode won't extend the life of the battery. It supposed to just help get the most miles per charge.

    Thank you for your quick reply. I live in New Zealand and the temp averages 20C. Lately it's been low teens and my temp bar only has 4 bars when usually it has 5. Heat isn't an issue with my battery. The SOH is 77.69% and AHr 50.96. It seems to lose .2% of SOH every 3 days or so. Only had 13 QCs too. I really hope it is a long time until I lose another bar. We are coming into winter here and the temp very rarely goes above 22C at the most.

    I can't predict the future, but I think you should be ok. Certainly the climate where you are is pretty LEAF battery friendly. Time can also be a factor in lithium battery degradation, but I'm sure others probably have a better knowledge of exactly how much and what to expect.

    I would consider joining this Facebook group of New Zealand Nissan Leaf owners and asking what their experiences have been. As I understand it, LEAFs in New Zealand are generally bought used by way of Japan, and may be slightly different from the ones built in England and the U.S.

    Please let us know how things go, if you can.

    There is no way any 2011 Leaf anywhere still has 12 bars. There is a trick dealers do where they reset the computer which brings the display back to full bars so the battery looks in better shape than it really is. Then someone buys it and it loses three or four bars very fast. I don't know where you bought it but whoever you bought it from was trying to pull a fast one. It may not drop any more bars as the computer has had time to readjust itself. If the range works for you then you will probably be fine but I have read a lot of stories just like yours from people buying used Leafs.

    I note that even with the mileage showing, it still has all the capacity bars.

    Ssssshhhhhhhh! Don't tell my car. It's a 30kwh 2016 now at 30,000KM. Still have all my capacity bars. And with the temperature now going
    a little above freezing I seem to have all of my range back even with the winter tires.

    Hopefully the cooler weather up there will help keep things under control.
