ChemId 100 was designed for Lithium Ion18650 cells with LiCoO2 chemistry composition. 

 Are you sure that new cells have same chemistry composition ? 

 Another question, why TI Chemistry Selection tool has thousands of different ChemIds for different cells type if setting 0100 would do the trick ?

You are right
My cells are lithium ion with a capacity of 4400 and a voltage of 3.7 volts.
In my country, Samsung, LG or Panasonic cells are not available and the only brand that I have used for a long time and was satisfied with and has real capacity and good quality is the Chamelion brand.
I only followed the instructions in the tutorial on the forum and I don't know exactly which chemical code to use.
Because the battery catalog does not give much explanation about its chemistry.

If you can guide me on which chemical code to choose, I would be grateful.
Thanks

 First, try to find same brand and type cells in TI chemistry catalogue.

That is, cells that are the same in terms of capacity and voltage as well as chemical structure as this cell (lithium ion)?
Did I understand correctly?

 Cells that have same brand and type. 

 For example: 

 Samsung ICR18650-28A

 Panasonic NCR18650B

 Molicel INR-18650-P26A

 First word is brand so company which manufactured the cells. Second word is cells type. It specifies cells capacity, voltage, chemistry composition and so on. 

This information is printed on the cell insulation cover.

That's right, I registered an ICR18650 with a capacity of 2200 per cell.

 Paste picture of cells label.

Is there no solution?
I searched a lot but I couldn't find a complete catalog.

Change the cells with some cells that you know chemistry.

 Download latest catalog from TI website. Take into account that Chamelion company should send their cells to Texas Instruments lab in order they add their cells into catalog. If Chamelion brand could not found there use GPCCHEM tool to find closest match cells with similar characteristics. Note that capacity does not matter for ChemId selection. Only chemistry composition and properties of the cells matters.
