I keep finding references that Sony uses different G Ratings to rate the cell capacity. Here is what I have found so far.

G4 = 2000mAh
G5 = 2200mAh
G7 = 2400mAh
G8 = 2600mAh

The Cell shown above has a G7 rating making it a 2400mAh cell.

Yep, seems to be a 'generation' thing. Generation 3, Gen 4, Gen 5 etc etc but there are other letters too, it's the number that counts:

G4 is actually 1960mAh according to the only Sony datasheet I could find that referenced them

I suspect the 'D' versions in the table above are for power tools, lower capacity & higher max. current draw, so maybe 'D' is for 'Drill'? Who knows.

G3 = 1800
G4 = 1960
G5 = 2150
G6, 6A, 6B, 6C, 6F = 2200
G7, 7C = 2400
G8, 8E = 2600

The 'GR' simply means Graphite anode, verses the 'coke' anode of earlier versions.

SF and SE on the cells is dependent on the plant that made the cell... 
SE = Sony Energytec
SF = Sony Fukushima

Note, the above is only what I have gleened from extensive searching, happy to be corrected

Here are some pictures and what I found out about the capacity of these cells:
G1 (blue without marking) 1400mAh


G2 1600mAh
will add picture when i find one. I am 99% sure that i have some...

G3 1800mAh


G4 (or anything with a 4 in the first 2 digits) 1950/2000mAh (depending on source, most laptop batterys spec them at 2000)
 


G5 2150/2200 mAh (again depending on source)



G6 (or anything with a 6 in the first 2 digits) 2200mAh (for once without any doubt)
 


G7 (or anything with a 7 in the first 2 digits) 2400mAh


8A (or anything with a 8 in the first 2 digits) 2600mAh


I hope this helps a bit with cleaning up the whole US18650GR situation Smile

Thank you for compiling this information. This certainly is confusing but makes sense. I will work on splitting them out appropriately.

Thanks again for taking the time to compile this. For the cells like G6, I assume we should treat the G6A as a separate model number (separate database thread)? Or are we sure they are the exact same cell with just a different wrapper?

Also, for the G1, can you please take a top shot of the ring so I can make a thumbnail?

I would love to see some technical document from Sony that shows the differences, but .... bloody Sony!

As best I can tell, there's no difference between them regarding voltage and capacity so probably no need to separate.
Maybe just add the others to the same 'model' column, so it look like (G6, 6A, 6B, 6C, 6F)?
Maybe that's too cluttered? Though there are other's with two model numbers (LG's for example)

I have examples of the 6A, 6B, 6C and the 6F and they're all testing about the same. Hard to tell though because some have had harder lives than others.
General consensus from the various forums on the interwebs is that they are the same capacity. 
I'm guessing Sony just made minor revisions of the G6 as the years progressed.

Edit: same deal for the 7 and 8, there are revisions for those too, I've got 7C's and an 8E's in my stash.
