hello sir
Could it be that the cells are dead or there is some other problem?

Cells produced in 2014 and have over 800 cycles.
What do you expect from such a battery ?..
Check the log.
Static unbalance is 65mV (at no current).
Dynamic unbalance is 154mV (in charge).
It is too much and causes charge issue. Cell 1 goes beyond safety limit and chip stop charge to prevent overheating.
Consider rebuilding a battery with new cells.
If customer is happy with small runtime like a backup battery you could try to precharge Cell 2, Cell 3 to minimize static unbalance. So battery could be fully charged.
