Hello team, I discharged with 600mA, I think it's good to see now. The battery is OK?

If you want to get actual battery capacity, then run full Calibration cycle. So Charge to Full then Discharge to 3.2v per cell by 0.6a. Consider relaxation periods.

Then chip will update the capacity.

Hello friend, Please look at the Cell 3

voltage is 0.

Open the battery and charge the cells 3 alone upto reach to other cells voltage. Charging current should be between 100ma to 300ma.

Then check, hope your problem will solve.

Open the battery and charge the cells 3 alone

There is no cell#3 !

Look first at designed parameters like The battery Voltage!

My opinion that battery is pretty good.

Ummm... he is getting 7 mAh 

7mAh was the capacity discharged over 20 seconds. The capacity is measured in real time.

I'm still skeptical, as on second snapshot the number is 42 mAh after 4+ minutes 🧐

First screenshot was made under 2.0a load while second under 0.6a load. Accordingly passed charge is different.

Even under 2.0a load cells deviation is only 2mV!

Which is excellent indicator.
