Since I lost my top capacity bar, the SOC and GOM (DTE, sorry Nissan) instrumentation has been very pessimistic. Also, I am now getting more miles between LBW and VLBW than before.

The estimated time to charge has been affected to the point that it now underestimates charging time. Therefore, I think the errors in the dash instrumentation are leading you to inaccurate capacity loss calculations.

interesting. i wonder how many people have range anxiety needlessly?

Sounds like voltage suppression.
I noticed you're still working with polymers.

Do you mean voltage drop due to increased internal resistance? That would be a possibility, but if that were the issue, it would have come on gradually instead of suddenly when I lost the top capacity bar. I think it is software-related (car's computers manipulating the displays) to provide more cushion against running out of power and requiring a tow.

I wanted to go back to the original Leaf advertisement..I was looking for any where in the ad. where it stated or recommended 80% charges..I found (0)

I see that they added positive Leaf owners stories to it also..I found one story very interesting where a family took their car on a 800 mile trip in Cal. where they used lvl 3 charges on the trip...
That was something I wanted to do and I explained my story here but was told here that would harm the battery..Kind of funny I never even left town or used a fast charger and still lost 2 bars..

Heres the Ad. I had not read it in over a year...

I think Nissan may have to change thier advertisement on the Leaf soon..I find myself only wanting to drive the car at night in Phx. now doing the summer..

They used only few DC chargers, and mostly used to top-up @3.3kW, then charge overnight. They did 180mi on average per day which requires just 3-4 stops for activity, and I think is not bad for battery as well.

You have to understand that folks share their opinions regarding the LEAF and how to use it, not all opinions are reliable. Just because another forum member carries a rabbits foot in the glove compartment doesn't mean that we all have to. Only time will tell what is good, bad and indifferent to the LEAF. During the current uncertainty over the durability of the LEAF's battery in hot climates we can expect a certain amount of hysteria until Nissan finally determine the cause and come out with what they are willing to do or not do about it.

But I read on another forum that if you place the rabbits foot on the battery pack it will soak up the excess heat and you can drive in temperatures up to 140 degrees! Is this true :?:
