I have tried writing again with NLBA and it changed. So, up to now it is solved

 It will drop back below 500mAh on the next grid point. 

 Send the dump to email to fix it

@djibattworkshop in this case 3,8v 3000mah LiHV (nominal is 3000mah, but real is 2800 or less)

 But some parameters in eeprom were changed to use LiPo 4.20v cells while another left for LiHv 4.35v.

@djibattworkshop I do not remember having changed voltages, I only changed FCC, and Cells voltage EOC value but may be I get confused as I am repairing other Lenovo battery with same issue but which has 3.7 cells. 

However I am sending you again original Backup eeprom, instead of reprogrammed one.
