The capacity is not that impressive for 2800mAh batteries (this might be because they are 4.3 volt batteries).

After shipping the samples to me, some print was added to the box.

Very nice discharge curve, the two batteries track perfectly and the capacity does not change with load.

I doubt it, they look like Sanyo UR18650ZT at 4.2 volt, but newer than the ones I have tested. Try my comparator and compare them, check 0.2A discharge curve. You can also compare the charge curve in the reviews.
