Just for reference that might help your query, we bought a 2016 Leaf almost 3 years ago with 46,000 miles on the odometer and 86.1% state of battery health (SOH).
We have since driven it about 13,000 miles, all local driving, with about 60 miles round trip in our hilly country being the longest drive we make in it.
We still show a GOM range in the high 80s to low 90s in the summer, and our state of health now is 83%.
We still have 11 bars though the odometer now reads 59,000 miles!
We use it totally in the local environment because it doesn’t have enough range to really go anywhere (24kW battery).
But given our experience, 8 years (or perhaps 9, depending on the actual manufacturing date), we still have 83% battery life, and are so completely happy with our purchase of the car in other respects as well, such as the solid feeling and handling, comfortable seats, very quiet inside of course, that we haven’t regretted our purchase one bit.
So I would urge you once your battery runs down, as others said above, to get a replacement battery, even if it’s only got 80% or 85% SOH, because you’re looking at as least 10 more years of running life.
I’ll never go back to gas engine vehicles. Convenience, no oil,no gas, none of that stuff, but also just the feeling of simplicity and increased reliability that comes with more recent Nissan Leaf models is not to be dismissed. It’s a viable, really useful and ecological way to get around.
