The value reported as SOH will go down and up over the course of the year. You cannot extrapolate a few months of changes into how it will look multiple years later.

Newer cars seem to not adjust the same as older cars.

My 2014 I can drive the SOH up from 90 to over 100 in a few days by doing specific things driving and charging.
Or drive the SOH down to 87 in a few days by doing different things driving and charging.
When I go back to "normal", the SOH returns to normal.

If anyone has a chance at a free battery its probably me. Not only does the warranty start when you buy - so it started for me after the car had already degraded sitting around for a year. But also i live in a hot climate.

As of this am it's going through its second big three month drop and I'm at soh 93.73% and it's not done with the big adjustment yet.

So I'm about 5 months into the warranty and it's the 93% already.

Of course I'm not yet convinced this is a real SOH.

Yeah, join the club. Guess what? Doesn't matter where you live because people all over the World are seeing the EXACT same thing you are on the EXACT same time schedule.

What was your starting SOH?

So I drove it home beginning of may and it was at 97.63% after sitting around for nearly a year on the dealers lot. But a month after I got it it went through its first big drop.

I post the data in the 40 battery thread.

Interesting. Even when sitting, its degradation curve is practically the same as mine. What was build date?

Good question. I know I looked before but don't recall. Early 2018 i think. I know it had literally been sitting on the lot for a year. I knew it and got a great price because of that.

I'm about 200 miles from it but can check when I get home tonight. Door jam?

When did they start rolling off the line? I wonder then how long it took to get to the dealers lot. So it may have been sitting for more than a year.

But the warranty starts when bought.
