Probably solved here: Charging rates and battery capacities - big difference? (#16 and #17)
Sorry, I did realize what you wrote (charge rate), but forgot to react on it.
I am not a specialist on cell chemistry, but I suspect that this could be causal for what you noticed.
Apart from that I agree with gauss163.
