Re: How To Tell If Battery Pack Has Been Replaced?

On the above, viewtopic.php?p=473995#p473995 is an example of a "wolf pack" losing 4 bars in Phoenix. There are probably more.

I'm not aware of any 4 bar losers on the "lizard pack" yet at https://www.mynissanleaf.com/viewtopic.php?t=24532.

Thanks. So more or less anecdotal. So no one has any form of a statistical study (not easy given the number of variables).

Thanks too. So if I had leased a '15 verses the '13, no significant difference in degradation, right? As you can see, mine is not that great,
but not that bad.

A 4/2013 or later '13 Leaf vs a 2015 would only matter much in a Hot climate. Otherwise I'd expect similar degradation, although I'd take more precautions like not charging when the pack was marginally hot with the 2013.

After a cursory review of the 2015 reports in a similar climate (SoCal), doesn't appear much better than my 2013. Actually, 2015s lost 1st bar
at 10K miles less (assumed same SOH delta). So I'll closely review 2013 vs 2015 in AZ.

GerryAz's data point at viewtopic.php?p=513453#p513453 seems to confirm the "lizard" pack is better than the "wolf" pack in Phoenix: viewtopic.php?p=473995#p473995.

Thanks. Luckily I'll never have to endure those temps here.

After reviewing GerryAZ's post here (http://www.mynissanleaf.com/viewtopic.p ... 50#p517750) on 1/30/18:

My 2015 did not sit on a lot (manufactured 1/2015 and purchased 2/7/2015) so it might be better than cars that spend some time in inventory, but it still has 10 capacity bars at a little over 55,000 miles in Phoenix.


It appears that his 2015 (Lizard) has lost 2 bars at the same point where my 2013 (Wolf) lost only one bar. Although just a sample of one,
i.e. anecdotal, the Lizard when statistically compared to the Wolf may not show a significant difference in degradation even in the AZ
type of climate. Where are the data to support the Lizard hypothesis, please?
