Right, I suppose that's possible, and they have proven to be working very diligently, albeit quietly. That said, I choose not to believe in this theory. I hope you don't mind. I took enough flak for trying to raise awareness last May, and even more so in the subsequent months. Although the right hand might not know what the left hand is doing when it comes to large corporations, I have to think that there was at least one element of surprise in the mix. It might not have necessarily been battery performance though.

I had a look at the GCR article you referenced above, and I believe that Ghosn was referring to the Mk2 battery there. He specifically mentioned lower manufacturing costs, and the MK2 battery and its modified packaging would fit the bill.

oh i dont mind if you disagree. disagreement and different POVs are is the value of this forum. there has been many times i thought for sure I and others were right only to be proven wrong.

in fact, for a lot of things, i want to be proven wrong. it only helps me. Only a fool would be upset when others pointed out their mistakes.

either way, it is only a few weeks away now.

It would surprise me not. They may not have used your model as is. But since they have much more complete data than we do, they may have used the models method and approach to the problem to arrive at a reasonable cut-off point.

Can you tell me why i did not get to the turtle mode when i was 3 blocks to go to get home??
my leaf was sitting in the dealer showroom for 6 months and i did not know about the 12 bar's
i am sure that i did not have them as when i charged the car only showed 102 or 103 Miles and
it used to get about the 72 or so mile after driving 10 or 15 mile at 48 MPH when new then it is gitting worse . I think the battery show get a good check as it was checked and the report show 5 Stars and now i only get 55 miles after a full charge , it starts out at 88 miles and drops after 3 miles to 70 MPH
and keep's going Down going at the speed of 48 MPH. What has to happen to get the weak or bad cell or cell's replaced. If I have to wait till the bar's get to 9 to have them fixed what will the miles that i can go?? :|

You are referring to the dash instrument that we call the Guess-O-Meter. Please use another method to determine how much range you may have. I recommend the Range Chart that is linked in my signature line.

Would it be possible to calculate the relative aging factor for the following location: St. George, UT 84770. It would be much appreciated.

you need to update your profile and add a location. it is critical in these kinds of battery situations.

at least update your profile or explain to me how your car was sitting in a showroom 2 months before the first American delivery

I only use the trip meter and add the guess meter to get the 55 miles

My car was sitting in the Showroom for 6 months as it was a demo for people to see before ordering the car as they did not have a supply. I live in Arizona and when it was 110 it got better mileage with the air on ,Does the heater takes more?
