What's the lowest voltage you saw under load?
They were bouncing around a lot while driving but I think I saw something like 2.79 for just a second, when I slowed toward a stop they went back above 3.00.
What's the lowest voltage you saw under load?

AHr=64.03 prev high 63.31
SOH=97% prev high 96%
HX = 98.2 prev high 97.25
GIDs= 278 prev high 271
I have had my Leaf about six weeks now and the numbers keep improving.

blogging about this but have you ever quick charged? reason I ask is because every time I do i see a significant jump in my readings. I think that extended periods in the cold depress the readings.

Car only has about 3400 miles on it, so 10% degredation seems a little high, especially since we are usually 80 chargers, and it has been only temperate and cold since we have had the car (in Chicagoland area).
Thanks

The other stat I have from Leaf Spy is a cell pairing voltage of 4.12 at near 100% charge per the car (between 98% and 100% - was preheating on L1 which pulls charge down a little).
is Hx the health percent? (if so that is also 90.01%).
Car was leased in May of 2013. 2 year lease.

I'd bet that the first one was old data. It can take 10 seconds for that plot to fully settle, or so, and is really only useful when there there is no significant power being drawn from the battery, or if you're able to keep a very consistent load on the battery for an extended period of time.Berlino said:Can I trust either one?

Extreme conditions may throw this off. I turtled with 8 Gids, SOC = 8.5%, min voltage 3.352, battery temp -8°C.
Actually, perhaps the cold was throwing the instruments or LEAF Spy off. In either case, proceed with caution
crabasa said:Whew! Just made my way through this entire thread. I am the owner of a Leaf manufactured in June 2013 that has less than 800 miles on it and is exhibiting the low SOH/GID symptoms described in this thread. I am currently in the process of executing a range test from 100% down to Turtle.
My question is: what kind of range am I looking for? I know the answer varies based on driving style, elevation, type of road, temp, etc. But what is the range of the mileage I should look for? I saw a post earlier in this thread of someone who went 114 miles on a charge.
I'm trying to evaluate whether I should pursue a remedy with my dealer (car or battery swap) or whether my car is "fine". Would love everyone's thoughts. I will post my data once I'm done with my test.
