I charge my cells to 3.4 volts and think I have charged them to 90% or 95%. I agree with @smoothJoey that those numbers look way off. There is no loss of capacity from a full charge at 3.65 volts to a resting voltage of 3.35. The chart implies that there is 25% loss. Also when my pack gets to 3.0 volts per cell I think I have 10% left and that chart implies 45% capacity. It is one thing to have the lights go out because one thinks there is some capacity to get through the night. I would not want to be driving an EV that said I had 45 miles left and then be stranded on the side of the road 10 miles later. I agree with the majority of the other charts published so far in this thread.
As a practical matter I rely more on my Coulomb counter to tell me how much I have consume since I last charged my pack.
