on Sony lithium ion cells look at the first two digits in the second row.

8A = 2600mAh

G7= 2400mAh

G6, 6A, 6B= 2200mAh

G5= 2150mAh

G4= 1950mAh

The last 5 digits of that row tell the manufacturing date.

digit 1: year. Q=2008, R=2009, S=2010 and so on

digit 2: month. A=Jan, B=Feb, …J= Oct

digit 3+4: day

digit 5: electrode history

so the cell on the photo was produced on Oct 29, 2008 (QJ29)
