They are a bit below rated capacity, actual capacity is 250mAh to 300mAh at low load. they do not support moderate or higher loads.

They do not contain energy enough to get warm.

[size=+3]Conclusion[/size]

These cells may be cheap, but compare to what you get they are way to expensive. Any decent cell will have about double capacity and handle higher load much better.
I will rate them as bad

Maybe the reason that capacity was not measured properly is the fact, that testing equipment does not follows specifications defined by battery manufacturer, as it was in case with 2700mAh AA batteries?
