Suspiciously high SoH?

[IAMTHESTIG]

So I just bought a 17’ SL it’s about 43K miles that has a claimed 98.78% SoH. This can’t be right considering its age. I would expect somewhere in the 80s. it was owned in Oregon and not driven a ton. I’m just concerned the dealer bought it from may have reset the BMS which could result in this perhaps incorrect health. I connected my LeafSpy pro and took a few snaps, at idle with AC on, under full acceleration, and regen. I dont know if this means anything useful but judging from the voltage variance w my limited knowledge it seems fine, but I wanted to get some opinions. those of you super familiar with this, do you think? It’s not like I can take it on a long test drive to discharge it down to 10% then measure kWh used to charge to 100 before buying so I guess I’ll just run with it. I only drive 30-40 miles a day so this will easily meet my needs even if the battery is only at 80 SoH.

Don't take my word for it, but looks like you have a 40kWh battery. Those are not standard in a 2017. There must have been a battery replacement?

Seems like you lucked out.

What range are you getting?

 

[Stanton]

With an AHr reading ~110, I can guarantee that's a 40kWh battery pack. If you select that setting in LeafSpy, it will then correctly calculate other parameters (like SOC/SOH/etc).

Looks to me like you made an outstanding purchase. Congrats!!!

 

[IAMTHESTIG]

They didn't say it had a new pack or anything. It does look like later 2017 models got the 40 kWh though. I don't know, I'm still skeptical....

We shall see after some driving. I bought an Emporia EVSE and am getting a 50A 230V outlet installed this weekend.

AFAIK the first Leaf to come with the 40kwh pack was the 2018.

I think you just won the Leaf battery lottery. The previous owner must have gotten a pack replacement and since they don't make the 30 kWh battery packs anymore, Nissan puts the 40 kWh packs in, instead. When fully charged, the dash should read very high, like probably +180 miles of range given the SoH. If everything is fine, mechanical wise, you should get all of the original 2017 range and more for the next decade, provided you take care of the battery.

What was the purchased price?

Your car's original pack was replaced. you have a 40 kwh pack. The original pack was 30 kwh. Based on the Hx, the pack is very close to brand new.

No 2017 got a 40 kwh pack. In fact the 2018 model year launched nearly 2 months late (although Nissan acted as if it was normal) likely due to a slow revamp to the 40 kwh pack sourced thru TN

In my research I did see that it appears the later 2017's had 40 kWh packs... but this one may very well be a recent replacement. Does anyone know if the QC and L1/L2 charge count gets reset with a new pack?

Anyway I drove it away from the dealer today with 79% charge and drove 66 miles in the city, had 42% when I got home. So that's maybe about 160 miles range. SoH is now reading 98.72, Hx 98.46, AHr 113.96.

I paid about $12.3K before taxes, fees, and some BS that dealers add. I wanted more like $11K but couldn't get it.

The numbers are not reset when done under warranty.

Did I not say this was a 40kWh pack in like the third post!

Nice. Makes me feel even better about just getting my 2020 with 22k miles for 12.7k. You lucked out with that battery and that car should last you a good long time.

How much did you pay for it?

Asked twice, and already answered--you got to keep up, read the thread RTFT

Oops. My apologies.

IAMTHESTIG was commenting about the possibility that the 40kwh bat was original versus DaveinOly's assertion that it had to have been replaced. I think IAMTHESTIG is correct about the *possibility* of it being original -- but DaveinOly is correct I think. No 7 year old battery even in the Pacific northwest would still be at 98% SOH........ Its a replaced battery.

 

[IAMTHESTIG]

After driving it some more days it really is doing good. Seems like a new pack to me. I am pretty happy with it. It has more than double the range that my previous ‘14 which had 77% SoH. And I bought the ‘14 in 2019 for about $9k I think, sold it in 21 for &14k…. So in the end I’m pretty happy.
