Battery Cell Question - Worth dealer diagnostic?
I have a 2021 Nissan Leaf SV with 33,700mi on odo. Got it end of 2024. I commute 2 a week on freeway (32mi one way) and local road and don't drive this car so much. Probably 1k miles a month or less.
Last year, I noticed when my battery has 60% and drive back home, it drops quite fast on this uphill to 20s% then as I go down, it regenerates very fast. Checking LeafSpy and I guess the reading just not super accurate. So, I let it slide.
Then last week, going to my regular commute, 80% suddenly drop to 40% uphill. Check the LeafSpy and I saw one bar significantly low. Since then, I've been keeping an eye and summarize that cruising in freeway put me between 50-80mV while the uphill at above 90mV.
Is it even worth taking to dealership for diagnostic (probably USD250)? since there's a recall too for the fast charging (that I never do since owning this car).
I had an e-Golf for 2 years that 4 of the battery cells went bad but I drove 38mi one way everyday back then.
