Open letter to Leaf owners, re: battery capacity loss

[Kathy Sokolic]

This was just posted by a Leaf owner on the forum, addressing the battery capacity loss.

Interesting.

My capacity seems to be going up and down...but I haven't tracked it well enough to know what may be causing the changes...?

I feel for these guys.  My guess is that it's a software issue that's misrepresenting the pack.  Or maybe that's my hope.  Either way it's too early to tell.  

A few weeks ago I was consistently getting 9 bars on an 80% charge.  But now it's back up to 10 bars for 80%.  The weather has been cooler, maybe that was it.

Many people on there think that letter is not saying anything new; some are somewhat

mollified in that at least the letter is an official acknowledgement from Nissan

that there is _something_ going on with the battery, if not an actual problem.

I'm hoping that it's a combination of temperature (which explains why most

of these incidences are in AZ and TX) and software/hardware miscalibration...

But you're right, there are many unknowns at this point.

I got 9 bars about 50% of the time in the past 15 charge-to-80% events.

There is a recent discussion in the forums about that:
