I got a bunch of 18650 from a laptop battery and I put them on a Opus charger.
The charger showed one with a voltage of 2.8V and the others with 3.4V
Then I charged them at 500mA them and the one that had 2.8V finished with 2200 mAh capacity (full), and the others with 1600 mAh.
Is this because the other 3 were not completely discharged and the 1600 mAh is not the battery capacity, but the amount of mA that the charger put in from 3.4V to 4.2V?
If I do a discharge refresh will that give me a read of the real battery capacity?
