Hi... I don't understand why in links (see upper)

talking about SE US18650GR. but:
- in first link - as Li-Ion battary (I know voltage must be 3.6 V and charging to 4.1 V)
- in second link - as Li-Po battary (normal voltge is 3,7 V and charging to 4,2 V)
Please let me know corrected info..... Thanks

Where do you see 3.6V? I see the same nominal V in both, 3.7V. One document is a very old product/company presentation.

I just know it - for Li-Ion battary - must be 3,6 V. for Li-Po battary - must be 3,7 V..... Just in case from my experience - XMAX B6 charger has 3 variants of set voltage for Li battaries - 3,6 V for Li-Ion. 3,7 V for Li-Po, 3,3 V for Li-Fe
 
Li-ion battery can refers to any Lithium-ion battery of any chemistry of any format. The nominal voltage can range from 2.4v for LTO 18650's to 3.8V NCA 18650's. I have 3.6V LiCO 18650's , 3.7V INR, NMC 18650's and some 3.2V LFP 18650's. 18650 is just a cylindrical shape.What really matters is the voltage range. Li-po refers to the Lithium polymer electrolyte conceivably it could be any chemistry of Lithium Ion cell. Datasheet would be the final authority as to what the nominal voltage is.

US18650S GR 1350mAh from 1997
 
I found several : SE (plant/factory) us18650GR....GREEN WRAP, BLACK insulator....but no G,
But with underline 7C124...
I THINK THIS COULD BE A G7, i have no clue, sorry
Testing CAN reveal, i have 150 or so, i will report back with ir and testing results, If they are good.
I hate to test unknown cells.
Lot of effort for a educated guess....

Yes, they are G7 cells with 2400mAh

G3 = 1800
G4 = 1960
G5 = 2150
G6, 6A, 6B, 6C, 6F= 2200
G7, 7C = 2400
G8, 8E = 2600
 
@Dragracer thumbs up from me!
Where did you find this info?

With kind regards Igor
