If you absolutely trust the PO's word they may have 80% cycle life left and half the calendar life.

I would not pay more than 25% new price myself, and even that only after doing my own random capacity testing.

Thanks John...so that would be around $30 per cell. What is the expected calendar life of these cells if used properly? The seller is being very open about the cell testing by providing cellpro 6 screenshots with charge/discharge and resistance readings etc.
Well certainly longer than they've been on the market so far, if stored properly, low SoC and low temps.

Extrapolations from lab experiments won't match real life.

If they are used in an EV or other high-C rate application, irrelevant anyway.

As a House storage bank only used weekends I'd guess well over a decade?
