Thanks leafkabob..
I think this is the worst degradation reported so far, do you always charge to 100%?


No, it isn't the worst. All the ones that have lost a capacity bar are worse. He rarely charges to 100%.

I don't charge to 100% very often and I just lost the 12th bar this evening. When we started out I made a point of checking to see if I had all 12. On the way home I noticed I only had 11.

Indicated range (trip distance plus SMRD reading) is 90-95 miles on a full charge. That makes maximum range (to turtle) 95-105 miles.

If the gid really represents energy in the battery, I am 10-12% low.


In late May, I find my SOC meter reading 242 on 100% and 204 on 80% charges. It looks like I failed to report gids for 80% when I first received my meter but it was around 212. We now have 15-16k on the odometer. I hope my readings continue to decline so I can get my battery fixed at no cost to me. I haven't yet discussed the problem with my dealer. I wonder at what point I should bring it up with the dealer?

anybody have a GIDmeter in NH or northeastern MA I could borrow? I'm holding out for a LEAFSCAN so I'm not building my own GIDmeter, but I am curious...

this morning. scenario, drove 112.8 miles yesterday with 4 stints at L2 charging in anticipation of the launch of DCFCs here. well, the Northern half of the state got some, we got nothing. hence the L2 time. drove to Chehalis to pick up my Sears ext cord (very nice!! heavy duty 12 gauge with plug lock!) which is 72 miles RT with a useless stop in Centrailia to look at the "coming soon" sign... but that is another thread i guess.

home at 5:35 PM and plugged in immediately. charge completed at 12:48 AM

i am at 16,998 miles. so basically 17,000 miles and .4% degradation. i think i can find a way to live with that

When you notice the car is not reaching full power acceleration and the battery has a good charge level.. keep an eye on the power bubbles!

If your annual battery check was due soon, that might be a good opportunity to mention it. Gids have some correlation to battery degradation, but we don't know what exactly it is. It's nearly certain however that it's not a 1:1 relationship. There seems to be a degree of seasonality, and the numbers should creep up again as the weather gets colder. I've noticed that you switched to 80% charging most of the time, this should be good for battery longevity.

This morning, 6/14/12, a full charge gave me only 242 gids. About 86% of "full". 80% charges have recently been giving me ~204 gids. Today's full charge indicates only 106 miles on the SMRD; I would normally expect to see 115-125 miles on the SMRD after a full charge. The crappy "bar" display still shows 12 bars.

I'll probably get it to the dealer in the next couple of months and see what they say about battery condition.

Will be nice to have more reference from TX but only 2 reports from people that have car for 1 year or longer and both of them low GID number about 240 at 100% charge. Hopefully more people will start to measure so we will know what is real situation in TX

I'm guessing that you aren't talking about the Phoenix LEAFs. There is no degree of seasonality here. When someone loses a capacity bar, it's gone. I find it highly unlikely that it will come back in the fall/winter. And my BCM which is based on the 281 raw number is very accurate in predicting capacity loss. Right now, I just lost another 2% which puts me at a 11% loss. I had 86% after a 100% L2 charge, now it's 84%.

My wife swears that my 12'th capacity bar turned back on for her for about 10 minutes about a week after losing it. Also, I did see an increase in capacity last fall so there does appear to be a seasonal effect. However, I agree that noone's battery is going to repair itself.
