Questions about the Nissan Leaf

Nissan still only claims less than 1% of their battery packs are replaced under warranty due to degradation, which I find impossible to believe. Because at one time it was pretty easy to find a lease turn in leaf with a brand-new battery.

That could be true depending on how they crunch the data. It was the 2011 and 2012 batteries that were real bad but production was low (9700 and 10000 in the USA) Even if they were replacing 20 or 30% of those early batteries in the USA that would be a small percentage of the hundreds of thousands of Leafs made globally.

You also live in an area with some of the worse conditions for battery degradation so you would see more than most people.

I believe it. Main thing now is to avoid the 40kwh batteries unless you are in a cold climate.

Why is that?

As a side note, I saw you said you were formerly anti-Nissan-Leaf. Gotta say, I'm anti-Nissan in general but this was the only EV I could afford. The control panel for the climate control is the stupidest ****ing thing I've ever dealt with. Just give me 3 knobs like a normal car!

From the buyers guide linked above:

"Let's talk about Nissan Leaf battery packs for a moment. The first two years on the market, there was quite an uproar over the battery packs losing capacity over time, especially those located in hot climates like Arizona, Texas, Florida, Nevada, and Southern California. Any battery will lose capacity over time, whether it is in a car, phone, or laptop. This is to be expected. But the Leaf's battery was degrading much faster than anticipated in these hot areas. So after 2 years the car's rated range may drop from 85 miles to 65 miles."

The 1st Gen leaf has had several iterations of battery

2011-2012 - Worst battery looses capacity rapidly
2013/2014 - unofficially Improved fewer failures
2015 - Lizard battery wears the best but only 24kwhr
30 kwhr - lettuce battery, looses capacity faster than 2015 and sometimes completely drops a cell
40kwhr battery- too new to really tell appears to be better than 30kwhr but that’s not saying much
60kwhr battery- too new to tell

The data on the 30 kWhr battery is interesting - I wonder if any further follow-up was done. If the battery continued to degrade at 9.95 per year Nissan would have to replace them under warranty after 3 years. I wonder if they initially drop a lot and then the decline tapers off.

I was asking specifically why the 40 kWh battery, but the above posts answered it. Thank you

The 40kwh battery cooks it's self. Probably comes down to packing nearly 2x the kwh in the same size and weight cells.
