After nlba1 full charge, it doesnt update in the capacity graph in bat info. It powers the laptop well, but there is a red cross on the bat icon, not charging.

Cells are almost fully charged but RSoC is 7% only. This is the issue. 

Set 12900 voltage on BatInfo tab, then press Power On button. 

Wait until Current() parameter will reduce to 50mA or less. 

Check if RSoC and capacity graph are increased.

Insert it into laptop, install Nirsost BatteryInfoView run it and post screenshot.

So clock & data lines are not making proper connection with the motherboard and battery is not detected by laptop.

There are so many topics about this here.

You need to restore battery connector pins tightness.

@torture OK! I will check the pins just after it finishes this:

'Set 12900 voltage on BatInfo tab, then press Power On button. 

Wait until Current() parameter will reduce to 50mA or less. 

Check if RSoC and capacity graph are increased'.
