Re: Poll : Number of miles before losing the first bar

Lost the first bar at 45441 miles and almost 40 months. Car was mostly garaged and rarely exposed to outside temp over 80F. I would say 80% of the time the car was at 80% charge. QC 70 times. In dry 75F wheater we can still make a 70 miles RT with 50 miles on the freeway at 55-60mph, reaching VLBW closer to turtle.

Well I can't say I've lost any bars yet... just turned 30K on my 2013 picked up 3/15/2013. I thought it would have happened already....not that I'm complaining :)

25,400 miles @ 2 years 10 months. Was hoping not to see it before I turned in the 3-year lease, but oh well.
I noticed you're still working with polymers.

In Minnesota? I'd have been mighty surprised if you lost a bar in just a year and a half that far north.

Lost my first bar at 27,400 miles... After driving it for 3.5 years in SF bay area.

Note mileage. I drive a 73M RT 5x week (probably not more than 25miles on an average for a whole weekend) and charge 2x daily to at least 80% in weather above 20F. Ideal climate but I'm probably on the high end of charging frequency.. not sure how that factors in to the equation.

Last winter most of my drives home were on 100% charging. Car parked in city ramp and temps were brutal...we had a MANY sub-zero days. Battery obviously tolerates that rather than the extreme heat.

Next question... is battery loss fairly linear? Is there accelerated loss ????

[EDIT]
Forgot to add my 73M RT is 95% 55-60mph...slightly slower during the winter.

For the first model years, 2011 and 2012, the biggest predictor by far of battery loss was exposure to excessive heat. This was first noticed by LEAFers in Phoenix, who lost as many as 3 bars in a year. By "excessive heat" the limited data suggests that starting with battery temps about 80F the excess wear on the battery kicks in and increases exponentially. Based on model year 2011 and 2012 data, cool climates like Minnesota saw much slower degradation. I'm at 7400 foot elevation in Colorado so rarely see days of even 90F and the battery temp gauge has rarely topped 6 bars, so my 2012 LEAF has all its bars and a 90% SOH after 31k miles. By contrast, my 2011, with fewer miles (22k), has all bars but only 86% SOH because it spent the first 18 months of its battery life roasting on the lot of a dealership in the Houston area, usually with a nearly full charge.

For 2013 and later model years we don't know if the heat has the same effect on the LEAF batteries. Lots of speculation, very little real life data. Nissan announced a "lizard" battery that is supposed to tolerate heat for the 2015 model year, but most of us think that this was actually rolled out earlier, possibly to some or all 2013s, but not announced because Nissan wanted to collect real life data before concluding the problem was solved.

In term of linearity of battery loss there is also a lot of interest and speculation on that topic but still very limited data, since the first LEAFs aren't yet 4 years old. Early suggestions were that the degradation would "flatten out" over time but the limited data doesn't seem to support that.

In my 2011 i didnt lose a bar in 3 years and 45,000 miles and you have a newer and likelier better (and bigger but not starting any rumors ;) ) pack so pretty sure you have a long way to go
2011 SL; 44,598 miles. 2013 S; 44,840 miles.2016 S30 deceased. 29,413 miles. 2018 S40; 129 miles, 491 GIDs, 38.1 Ahr available, 100% on everything else :)

Lost my first bar today at 47,840 miles, ahr = 55.53. My 2012 was manufactured in January, 2012 and I purchased it in April. Not 1 QC even though I have the port - just no QC chargers around. I have a 60 mile round trip commute and am located in Upstate NY south of Rochester. Losing the bar wasn't unexpected - I knew I was getting very close. I record my battery values everyday and had read that others lost their first bar at about 55.5 ahr. I was hoping to make it to 50,000 before it happened, though.
