There you go...pretty good evidence that QC is not harmful to the battery! I think you got an awesome deal (well, I don't know much you paid, but I suspect with 100K km on the clock you probably got a good deal). With that kind of battery stats, you should be able to get plenty of more use out of this car!

I've paid 13.000 euros and got 3000 euro municipalities rebate. Effectively the car cost me 10k. The dealer had about 40 old leaf taxis for sale this year. Most of them were sold to traders in other EU countries.

I think QC are not harmful, but leaving the battery charged at high percentage is for a long period of time is.

Interesting. That's about 72.3K miles. With other stats like that and the table at viewtopic.php?p=455984#p455984, it seems like it's on the verge of losing a capacity bar soon though.

I'd imagine that Amsterdam is a pretty mild climate. I've only been there once in the winter.

OK, battery degradation - 2012 SL, 14.2K miles, parked outside always, including in the sun, and it gets hot in LA, but not like Phoenix, not for more than a week at a time usually. Wife uses it for work, including twice a week at night. When she returns home the predicted mileage is (was) usually down around 40, and she charges again till it's full.

We're down to 11 bars. And where our predicted mileage regularly showed 80-90, now it's in the low 70s, and when she gets home it's as low as 28.

Cell balancing. Any time you leave the car sitting for awhile, particularly at full charge, it will have a chance to rebalance and reclaim some of the capacity lost by the imbalance.

Fantastic, now I'm up to 43.75 no way I'm going to make my warranty date now :-( guess I will start saving for a new battery. I was reading on another post about a 20/80% split but I don't remember the conditions.

Two routes you can take, try to preserve or try to accelerate the impending failure.

Best way to kill lithium batteries in my experience is to run them dead. Do you have another car? Run the Leaf to turtle and park it and don't plug it in. I would imagine after a week or two it would have discharged below the safe level and start to go bad fast.

Shame I did not know this. I was told to run it up to 100% and leave it for 2 weeks. Which is what I did. I am not able to let it sit right now. BUT I do turtle it almost every day trying to get to work.

I think I have extraterrestrial battery on my Leaf.
Did one 100% 59 minute charge at DC-station.
Hx/SOH went up after DC-charge from 95 to 98,39%, SOH 98%.
Unrealistic numbers. I felt 95% was more-or-less correct.

279GIDs my *ss :roll: Not possible. Battery is 2,5 years old, 46600 miles, almost out of warranty.
Short range EVs <30kWh -- Medium range: 30-60kWh -- Long range: >60kWh
Charging: Trickle <3kW -- Normal 3-22kW -- Fast 50-100kW -- Supercharging >100kW
