Lizard Pack Holding Up

[DaveinOlyWA]

I'm looking at a used 14 with a build date of January 2014. Are we fairly confident that would not have a lizard pack?

too early. there was "some" evidence that Lizard packs were installed in current builds before the official announcement but you probably missed that by at least 3-5 months

Not a lizard unless it had a replacement pack put in after initial build.

Lizard packs annouced here http://www.mynissanleaf.com/viewtopic.php?t=17168 on Jun 27, 2014 meaning you'd have to have a July 2014 build date to have any reasonable hope of getting one.

You might hope for an outlier if you got a tail end 2014 Model made right at the end of the 2014 MY run but the odds are they put out 2014s with the leftover 2013 packs and started the 2015 MY with the lizard pack when it came out.

Besides the "lizard pack" is only barely better than a 2013 pack which is only barely better than a 2012 pack. It really isn't worth much of any difference in money to me.

The 30 kWh pack is a different story. We can measure it's worth easily.

Just want to clarify and correct the above statement that the announcement of the "Lizard" stated that it was the pack used in all 2015 cars. The 2015 cars started production in 4/14, so any 2015 car produced in that month would have a lizard. Other than contacting Nissan and confirming your S/N, the only way you would know you have a lizard is to know that your pack read 292 max Gids when new. My 2015 (mfg 4/14) read 292 Gids until about 6K miles. I'm not aware of any other Leaf pack prior to the 2015 lizard that read that high.

The above post is correct though that the lizard isn't much better than the late 2013 MY packs. The early 2013 MY packs were identical to the 11/12 cars.

Kind of goofy but a Leaf made in Feb 2014 is a 2014 model and a Leaf made in April 2014 is a 2015 model with only two months difference in build date.

I'd love to know how tight that gap was. When did 2014 MY stop rolling off the line?

From what I understand, 2014 was a very short model year and production run. I have a friend who has a 7/13 produced 2013 model Leaf, so it looks like they only made the 2014 from 8/13-3/14 give or take. I'd be willing to bet that there's a few late 2014 production models that got lizard batteries but I think there's really no way to know for sure if your has one unless you ran some readings when it was new and noticed a 292 GID reading.

I've seen multiple 2013s with December 2013 build dates, so 2014 production was very short.

mine was 11/13 picked up Dec 22

(Leaf 2) with December 2014 new battery install (Lizard), has regained to 91% SOH in June 21st 2016 from a low of 87% SOH in Feb 2016. More detailed stats are on page 14 of this thread.

All of the stats for this month are showing lower than last month with the exception of SOH, AHr, and Hx which read higher. Battery temps are reading at 104 degrees and it is 4 a.m. and it was not on the charger or driven. This car also parks over grass and not garaged.

I am surprised that Leaf 2 is reading higher in SOH. GIDs are not reading higher though... With the better SOH stats, maybe this battery will make it to 3 years! The next one is on my dime.

c4Lvin, thanks for pointing that out! I corrected it to read June instead of July.

I hope you meant June 2016 unless you are a time traveller.

higher GIDs means more storage capability or a better balanced pack at the top end. Higher SOH is supposed to mean the battery pack is happier. keep in mind; higher top end balancing is not necessarily a good thing especially if you are not needing maximum range. for maximum life its best to keep SOC in the 20 to 80% range. Of course, the range being so limited makes this an undoable challenge for some so you have to weigh your options. Fully charging is supposed to be bad but as long as time at high voltage is limited, I am seeing a small drawback if any but without a side by side car to compare, its impossible to say. the only real option we have is to do what we are doing; report our experiences with details of how we charge, drive, etc.

As I've now had my battery for just over a year, so here's another update:



Comments: With the colder weather of winter and spring, the battery has been holding pretty steady. I'm currently at about 258-260 GIDs, 60.25 AHr, 94% SOH and 90.4 Hx. We'll see what happens during the next 6 months...

Update: We're now well into the heat of summer, I'm happy (ecstatic, really!) to report that my battery capacity has remained stable even over weeks of 90°+ F temperatures (and multiple days well over 100° F). Here's my latest chart:


In short, the AHr reading have been holding steady between about 59 and 61 since the beginning of the year. I'm crossing my fingers that it'll stay that way!
