Feb update. 316 GID's 68.96 AH, SOH=86.76%, Hx=66.33%, 75049 total mi. 30120 mi on new battery. 20 DCFC and 579 l2 charges on the new battery. The battery is continuing to slowly degrade. In the cooler weather, I still lost a GID last month. I'm down about 13% from new. 20 months in, the old battery was down 21%, so the new battery is doing better. The difference is notable and I expect to hit the 100K warranty limit well before the new battery would qualify for replacement. I still expect to be down about 25% at 100K. I expect that as the weather warms up deterioration will accelerate again. I'm looking forward to Tesla's battery day announcements and the reveal of the ID4 at the Chicago Auto Show. Fenix power is still a no-show at this point.
My OEM 30 kWh lost at the rate of 1% per month over 38 months after being sold new so I think your last battery is holding up much better than my first on. I still have not heard from the dealership other than they did not want to do the swap and thought doing a buy back might be better for Nissan. They finally told me they had never replaced a Leaf battery but had done a few BMS updates.
Thankfully the National Leaf Rep thinks Nissan standing behind their written battery warranty is what should happen so we will see what happens but they have only had my Leaf since 30 Dec 2019. At least last week the National Rep called me and did state they are using the 40 kWh batteries to replace failed 30 kWh batteries so I am wanting them to get moving because I left it expecting a 30. Maybe them dragging their feet was a good thing after all.
The new battery is better than the first one and fact is behaving just about as well as I expected the original to. At the current rate, I expect the new battery to last about 75,000-80,000 miles which is what I was expecting from the original battery. I fully expected the battery to fail under warranty at 70,000-90,000 miles. A replacement battery would get me out to 150,000 miles and I could write off the car at that point. If a new battery was cheap enough, I might replace the battery again or more likely buy a new and improved model. A used Model 3 might also be a possibility. Unfortunately, my first battery crapped out at 45K and the current battery will outlast the remainder of the warranty. If the battery had matched Nissan's goals, I would have had 80% capacity at 100K and could have driven it to 150K easily. Silly me for believing Nissan.
Good luck on the 40 KWH battery. I expect that it will actually go 100,000 miles. Between the larger size and improved manufacturing, it ought to be more much more durable.
2016 SV, New battery at 45K mi.
