Hi y'all. First post in about a year, I recon.

I had my 281 back when my LEAF was new, and wrote about it extensively.
Today, after 24,000 miles and two years, I max out at 233. That's 83% of original capacity.

Every morning my LEAF promises about 89 miles, and gets Low Battery after around 45 miles of typical driving.
I've met slow learners, but this range guess-meter takes the cake.

wow, that is a lot. where are you located?

I usually get anywhere from 105 to 118 miles estimated in the morning in Eco mode which is the only mode I ever use besides neutral

Yowza, that is really bad.

What sort of roads do you drive on?

I'm at 28,000 with the same Gid count, and I get an easy 60 miles before LBW. So your issue has to be down to either driving style; terrain; or maybe both.

FWIW, due to the disparity between Gids and true SOC, 233 Gids is actually around 87% of original capacity based on SOC.

SOC has very little (or "nothing") to do with Capacity.

No matter what the capacity, charge to full and you get about 95% SOC,
or charge to 80% and you get near 80% SOC, assuming normal temperatures.
But, you could have 30% capacity loss.

My experience with my first Leaf was very much like this. I think I could hit about 240 after 18k miles. And I never let it sit near full although did let it sit at 80% (which we now know is not all that different from "full"). I also didn't pay much attention to the temperature (being in Coastal SoCal) although for over half of 2012 it was common to see 6 temp bars. Only once did I see 7 on a summer day in Fontana with ambient temps over 100F. Now that I can see pack temperature I'm trying to keep it under 25C (ie 5 bars). I know that will be a challenge in the coming months..

Can you imagine the uproar that would occur if ICE owners were told that they had to keep the gas tank under 25C or it would shrink and they'd loose capacity :lol: ???

OK, so the disparity is between Gids and 100% SOC then. Same difference.

I believe that 100% SOC would correspond to 300 GIDs
on a new battery pack. But, we never charge to a real
100%. Stopping the charging at about 95% "real" SOC
helps preserve the battery life.

Loosing 50% of the original usable capacity might give you a
maximum of 140 GIDs, not 150.

However, the SOC would still be about 95% when "full".
