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.
The batteries looks good.
