So I'll answer my own question now, the answer is NO. I almost thought so, but it wasn't the deciding factor. It also says so in the instructions. After the discharge process (discharging + charging), only the value of the charged mAh is displayed at the end, the value of the discharged mAh is no longer displayed. Maybe someone knows a trick to get this value? But if I just press the display button, I get a mAh value that is probably the charged mAh. Good old days of the Charge Manager 2010, which I unfortunately can't find any more ... it simply displayed both, but unfortunately it died.

Yes, exactly as Avchunziker wrote

Yes. When "Full" is displayed, press the display button - then all values are displayed in sequence, including mAh.
