You can't read data from this battery since there is no smart controller on the PCB. There is only EEPROM memory 24C04 or 34F04.

Post a photo of the PCB.

This is not genuine PCB but a china replacement.

Can you post the markings on the 2 chips?

On the left is the eeprom memory but on the right is some other chip that is not preset on genuine PCB's and im not sure what the chinese have done.

If they have also integrated an SBS compatible chip maybe you can read data.

Have you tried connecting to NLBA? Pinout is printed on the PCB.

I connected it to the nlba device by looking at the writings on the pcb

Is there a bagging style you would recommend?

Which pins should I connect?

So the standart 24C04 eeprom is there but i can't find any datasheet for SA1414SE so it's function is unknown btu i think it's just AFE chip.

Like i told you before you should not be able to get communication from this battery but since it's not a standart PCB you can try.

 

P- to NLBA G

GND to NLBA G

C to NLBA C

D to NLBA D

+ to NLBA V

If the cells have voltage you can test if the PCB is funtional.

Bridge P- & GND contacts on the connector, measure voltage with multimeter between P+ & P-.

Voltage should be present.
