Agreed, that's why i posted to back you up.
Now, any cell can fail, new or used. New can fail right out of the box and it happens more then the EV community would like. Folks that run several dozen cells always buy a few extra in case of premature cell failure. Buying used has it's advantage that all but guarantees no premature cell failure on first charge because they are been in a working vehicle for some time.
I'm not saying a used Leaf cell will last the 10 years Nissan warranties it for either. I have a extra cell in case of failure. The trick is catching the failed cell early before it becomes a safety hazard. I do this with a cell balance detector circuit that costs less then $10. Here's the link to a simple battery balance alarm that I use.
