 Dynamic data were read correctly on Charge Tab, so communication was Ok at this time. Check the wiring.

Do not select this box when reading Maxim chips or the connection will break.

The chip has been reprogrammed so if you know who has done the job i recommend you to contact him.

The cells are garbage but cycle count is 1 and production date is 26.11.2020.

Very Nice.

 Not at all. Use this practice instead of continious read. 

 - confirm No read button is pressed 

 - connect wires 

 - press Read Once button

@torture Cycle count is become one when I replace the cells. The cells are new. Something is wrong with the chip. Showing locket, can discharge but can't charge

@torture This was a used battery, fuse was blown. After I have changed the cells. About history of this battery, I have no idea.

@djibattworkshop The begging battery was fully discharged, and fuse was blown, and that time battery was not detected. After the fuse repair I changed the cells and got these values on the photo.

 So you dont know initial cycles. Because battery was not read at all due to deep discharge. Wonder why you say cycles were changed to 1 after the cells were replaced.
