You are probably in a situation similar to ours: your car likely sat on one or more dealer lots for a long time - possibly in hot weather - with a full charge before you bought it. Just avoid that scenario while you drive it and it will likely converge with other '20 Leafs in total degradation.

Does this seem about right?
It's on the high end, but within the range others report.

It is your first data point, You will have a much better idea of your personalized car degradation trend line in 2 - 3 years. Car battery degradation is mostly climate related but also owner determined. Lefty can point you to threads that discuss these variables and mitigation strategies.

Hi!

First time posting here - loving my Leaf!

Just got LeafSpy and checked the stats on my 2020 62kWh Leaf's battery.

The car is 15 months old and has just shy of 4k miles on the odometer thanks to lockdowns. No DC fast charges, regular charging has been at 3kW (fault on charger) and have just moved up to 7 kW charging (BP have replaced the faulty unit).

If I read LeafSpy correct, I have lost 4.7% of battery capacity in 15 months, which seems to tally with the max. range being reported.

Does this seem about right?

Sorry if this is a bit of a newbie question, but I have no reference point!

Also, is there anywhere one can get a data set of batteries, miles, age & SoH readings?

Happy to plot it, but I would like to get an idea of what is average and where SoH heads over time/miles.

Many thanks for anything anyone can contribute!
You are normal. Loss during first year generally ranges between 4 and 8%, 2nd year 1 to 3% then it drops to about 1% a year. Despite the wide ranges, after a period of time, most of us will converge to the same range of numbers regardless of location, miles driven or charging habits.

Mine @ 15 months was down 7½% which was lower than most, at 18 months 5¾% which is just a pinch higher than the average.

In short, battery health/life can be improved by doing these things:

* Don't charge when the pack is hot if possible, according to the battery temp gauge. Anything in the upper* or rightmost 1/3 of the gauge is "hot." If you have to charge, don't do it with DC Fast Charge, aka "QC."

* Don't leave the car sitting with more than 70% or so charge. If you need the full range, charge it to 100% with the charge timed to end shortly before you leave.

* Keep the state of charge (SOC) between 25% and 75% when possible. If this means charging once every few days instead of every day, that's fine.

* 7 temperature "bars" or more on the Gen I Leaf is hot. If your climate allows you to avoid 6 temp bars as well, that's even better.

In short,
Good list. I summarize it as "the LEAF battery is not an egg. Do not boil, poach, fry, bake, or microwave."

Sticking the car in a poorly ventilated garage on a hot day falls into the 'bake' category.
Parking on 150F tarmac is frying
DCFC is microwaving

Many thanks for the posts and advice - really helpful.

The list from @LeftieBiker is gold!

Good to know this is in the normal range and I may have not helped by 'egging' a bit last summer. Nissan seem keen not to worry customers about batteries and so the car was left with a high SoC too much - and not much driving was done.

I am keeping between 40% and 80% now, but I'll take the advice to drop the upper end to 70% as I don't usually do more than 40 miles a day plus can charge cheaper overnight.

If it helps, 3% is like 13% because the Leaf hides capacity near the end. ;)

Latest battery bms update complete on my 2019 S+. SoH increased from 93.59% to 94.00%. I was hoping for a bit more, but better than down. We have stopped DC charging the cars as of mid June, so let's see if that is positive to SoH over time.

Hi Everyone,

As a first time EV owner, I can't thank enough for everyone share their insight about their leaf

I got a 2019 Leaf SL Plus (62kwh) about 2 years ago here is the stats I got off

Ahr 162.71
SOH 92.24%
HX 107.46$
QC84
L1/L2 125
Miles 10,428

Took me a while before I got a Lv2 charger up and running this is my my QC is a little high

I was hoping if anyone can share their thought on the state of health of the battery, while I expect some level of degradation over time, I wonder if 7.26% for 2 years is reasonable. I'm in the New York City so I have a fair amount of cold weather.

Apology for rookie questions, any insight will be greatly appreciated

Thanks
