Just imagine if you had started with a 24 kWh pack. This is why I try to warn people against the simple conclusion that the warranty period is long enough to get a new pack. You also have to be able to make do with the degraded battery for a while, and the while can be months and months. And in winter.

I was fully aware of the '16 Leaf battery challenges when I purchased mine new. However, for the ridiculously low price (after tax credits) that I got for it, the stupid low TCO, I'd do it again in a heartbeat because even now it fits the needs of our family. If someone asked me about it I totally would be transparent with these '16/'17 Leafs and what they may encounter.

Re: 2016-2017 model year 30 kWh bar losers and capacity losses

For the first time this winter the battery pack temperature in my Leaf hit 5 bars. I normally see the SOH% degradation slow down during the winters. Being curious as to where SOH was with warm-ish pack, I charged it up and gathered some data earlier than I normally do (typically the first of the month). It's amazing that it's dropped 3.57% SOH since the August 26, 2022. Data is clear that the degradation rate is happening faster as time/miles pass. In September I figured that the 4th bar would drop this summer. Now... I'm thinking this spring.

For a bit of context... Battery capacity bars dropped on dates in the red columns and the capacity loss per 5K miles was determined from the first full charge after the LBC software update that was performed on 6/20/2018.

Re: 2016-2017 model year 30 kWh bar losers and capacity losses

Took my leaf into the dealer this week to get the battery warrantee process started. Turns out they needed to keep the car overnight for testing, however I received a call early the next morning saying that the new battery was approved and put on order. cool!

Unfortunately, I wasn't told which battery was ordered, or when the expected delivery date would be. The only information they had for me was that it was the same or equivalent part number as the original battery, and no info at all about arrival date other than "it could be a couple days, or a couple weeks.. we don't know."

So, I guess I'll be surprised when it comes in!

They all get the 40kwh battery now. It's in writing from Nissan. Congrats!
