Re: Are 2013 and 2014 Leafs beta testers for the Lizard batt

I'm pretty sure LEAFfan's 2013 lost its first bar faster than the 2011, but that it stabilized somewhat after that.

I do not think the 2013s contained the "Lizard" battery, but I do think they were tweaked somewhat from the 2011/2012s.

When enough data came in, they decided to make it standard for the 2015 Leafs. Some of the earlier Leafs may have it, a lot probably don't.
I would rate electrolyte purity as a minor tweak and that minor electrolyte tweaks have been occurred on an ongoing basis

I also suspect that high purity, major electrolyte tweaks takes time to ramp up production, so that there was a 2 year period where both prior and future electrolyte was used as supply improved. I don't think that Nissan would wake up one morning, head off to caltex and just started using standard grade chemical for some of these additives, (others - yes they might) it would take time to build and commission the supply of the purity required.

I have almost one year and 13K with one summer in Maryland and am currently still at 101% health.

2010: Nissan engineers are convinced they have a good battery, Management makes it and markets it in MY 2011 and 2012. By the end of 2011, they realized the battery had a severe Achilles heel. Researchers start frantically developing a better battery during 2012. By the end of 2012 they are convinced they have a better battery. BUT marketing and management say, "no way are we going through that boondoggle again, we are not announcing a better battery until we have real world data so that we don't look like fools again." So they announce a "minor electrolyte tweak" for the 2013 Leaf, but it is actually what they think will be the Lizard battery. If it doesn't work out, no big public relations problem. If it does work, they announce the New Lizard Battery for the 2015 MY.

So they install the (as yet unnamed) Lizard battery in all 2013 and 2014 Leafs, use a variety of programming tweaks to see if changes in the BMS can give an extra couple of miles of range (accounting for the observation of many MY2013 owners that Gids, AHR capacity, etc are all over the map), sit back and collect data via carwings for all of 2013 and by the time a year has gone by, it is clear that the new 2013 battery is MUCH better than the earlier batteries. They smile, give a big sigh of relief, and announce the Lizard battery for 2015 (the MY 2014 has already been out a few mo, so they can't announce it for that).

Any of this seem unlikely either from the information that is known, or for the likely behavior of a big car company?
my view is that Nissan Engineers thought they had a great battery setup but it was nixed by marketing due to a slight extra cost and another 6 months delay to bring it up to production ready status. It was then decided to use the pack from the last prototype instead

I agree and LEAF fan also got one of the first 2013's making it even less likely he got something "advanced"
