this is just sad ... I reconnected all 3 batteries for this test and ... the result is crap.
The batteries are probably really old, as the QC sticker shows, they were checked OK in 2017, when they were probably already used in a laptop for 3-5 years. Lame... like 30% of their original capacity is left... :(
