on the battery as the Leaf *does* degrade its battery by 40% to approx
60% capacity in approx 50k mi in warmer climates (that is the point
where Nissan gives a warranty battery replacement, even though they
promised 70% but re-calibated the battery to lose the 4th bar around 60%
capacity and triggering the warranty if it occurs within the warranty
limits for time and mileage.)
When I first got my Leaf, I was astonished at how crappy the
instrumentation is/was. Coming from the conversion world, I expected to
see, or find out, how much energy went into the battery and how much
came out. Instead, I had these twelve "bars". Unacceptable
granularity. Later, I found the "bars" were not even of equal value.
After some pondering, I came to the conclusion that Nissan did things in
that way to hide information from their customers. What other
explanation could there be?
Even more astonishing is how Leaf owners accept the situation and speak
of almost meaningless "bars". I'm not surprised to learn that Nissan
dynamically recalibrates "bars" to manage their warranty threshold.
