A good post for an existing topic. Mods, please merge with the 2013 bar loss topic.
The forum for all aspects of the Nissan Leaf

Definitely not lizard battery, which didn't begin until model year '15. See http://www.mynissanleaf.com/viewtopic.p ... 06#p513306.Silverfish wrote:I hardly knew ye. But I knew it was basically a 10-bar Leaf when I bought it about 2 months ago.
Stats, for the curious:
2013 Leaf SV (built in 2/2013, so probably no lizard battery)
...
I hope the downward trend doesn't continue quite so quickly. But it is what it is.
Ah, sorry. I did a quick Google search and didn't find an existing topic. It's fine with me to merge this into whatever existing topic the mods choose. Or I can just delete it, if I can delete topics I opened.cwerdna wrote:Please don't open new threads for each capacity bar loss. MNL would get out of hand if everyone did that.

Also, some of the (well, at least one) moderators have complained about people unnecessarily starting new threads.

Interesting. I had thought that the lizard battery didn't officially appear until 2015, but was actually quietly put into service in later 2013. I hadn't realized there were gradations of battery types in between.cwerdna wrote: Definitely not lizard battery, which didn't begin until model year '15.

The 4/2013 and later built '13 Leafs and presumably all '14 model year Leafs seem to have a better chemistry, but not as good as the "lizard" battery.
If the downward trend continues as quickly and you don't live in a hot climate (I have no idea where you're at), you were a victim of a reset.
There are several generations of Leaf battery, most of which I have given nicknames to distinguish them from each other. The first, terrible pack made from 2011 through March of 2013, is the "Canary" pack because it is not resilient or long-lived except in optimum (chilly) conditions. The pack introduced in April of 2013 I nicknamed the "Wolf" pack, because it is tough and resilient in all conditions except sustained high heat. The "Lizard" pack you know about. It is somewhat better in extreme heat, but still not fantastic. Then in 2016 Nissan took two steps backwards with the "Lettuce" pack, with more initial capacity but such terrible degradation that it can easily fall below a Wolf pack in range after two years or less. They have recently introduced a firmware patch that will supposedly fix the issue, but I remain skeptical. The 40kwh pack in the 2018 Leaf seems, from very preliminary data, (unfortunately) to be another version of the Lettuce pack as far as durability of capacity goes...Interesting.

No, lizard pack was NOT put into service in 2013. It appeared in model year ’15 Leafs, that began production sometime in mid-2014. Please see earlier links.Silverfish wrote: Interesting.

The 40 kWh pack is too early to tell, although I would not recommend anybody gamble on it unless the car is severely discounted.LeftieBiker wrote:There are several generations of Leaf battery, most of which I have given nicknames to distinguish them from each other.

Based on a firmware error in reporting capacity. Dyno testing shows that these batteries are similar to the "Lizard" packs, that reported capacity more closely matches the independently measured capacity after firmware updated.LeftieBiker wrote:Then in 2016 Nissan took two steps backwards with the "Lettuce" pack, with more initial capacity but such terrible degradation that it can easily fall below a Wolf pack in range after two years or less.
