As the topic above, what is the main difference between these 2 batteries?

i manage to find some info for the 18650-26FM

looks like the discharging rate are maxed at 5.2A. which is much higher than the F ones? any idea?

i have ordered 2 from a chinese seller. sending by fedex which is expected to arrive around 1 week.
any suggestions on how to test it?
equipments available:
Oscilloscope, Multimeters, Chargers (maybe dischargers),

Edit: a photo from the seller. this is the exact one being delivered.
