Hi Lucky,
Thank tyou so much for your detailed response and the valuable information you provided.
I indeed noticed the low Hx rate but after spending some time on forums to read everything i could find from many users experience in many countries, i came to the conclusion that i should not care to much about this Hx value. I was aparently wrong.
I won't be able to do any further test unfortunately as the car is located at 300 kms from the place i live, and drove there specially last week-end to meet the owner and test the car. The car will be available next month, as the current owner is waiting for the delivery of his new car.
So now, it's on me to take the decision whether to buy it or not, with the risk it entails, based on the values and info i shared, and responses i got from persons with more expertise than i have.
However what i know: the current owner bought the car when its mileage was 30,000 kms and since then drove only flat roads, 60km every day of the week to go to work (30 in the morning / 30 in the evening, no highway). He mainly charges the Leaf at office during day time most likely from 4 or 6kwh wallbox (he bought L2 cable). The car spent most of it's life in north of france, close to belgium, where temperatures are generally quite low. He never did any QC (leafspy reported only 26QC, aparently by first owner).
Last service from Nissan in november 2023 reported "excellent battery condition" but no further details...i am not even sure they plugged anything on it...
I am not skilled enough to understand the level of risk i am takink if i buy it but i don't plan to change any cells for sure. If car became unusable > Bin!
I think i'll pass even if it was good deal on paper. If experienced electronic enginneer wouldn't take the risk, i shouldn't neither. There are plenty of Leaf on the market
If anyone has opposite experience, i mean low Hx for a long time, with no particular problem and no fast degradation preveting the car to be used, it could be interesting. After 5 years of use, i will get return on investment (i spend around 1500 dollars in fuel to go to work every year) even if it's value drop to 0.
Thanks
