Bought these in a 4 pack, initial first charge on all of them was between 750-800mah. See the picture below for what a discharged one from 2.8v took in, not sure who makes them

This brings up an interesting point.
There must be a voltage that we consider the cell to have zero capacity. As the cell is capable of being discharged past that point, the measured uptake in capacity can show as above the rated capacity.
I would imagine that 2.8V is below that mark and that's why you are seeing raised uptake.
I wonder what voltage is considered to be zero capacity?

My theory as well but i posted for more feedback, i have another one on charge thats gone to 810 both batteries were used in a Malkoff BG v1 until the light started flashing at me.Cheap as chips so not bothered if it reduces lifespan i am experimenting.
