I cant comment on the laptop cells.
Looking at the pics in the link under product details, 1st pic, 3rd battery to the right: the date code appears to be O37C… at least to my eyes. So these appear to be 37st week of 2010, which would be 1st week in October, 2010. If Im right about the code and the dates in the pics are representative of the actual items being sold, and the cells have been stored in a cool dry place without moisture, these should still be good.
From this example:
L37A is their production date code.
K=2006
L=2007
M=2008
N=2009
O=2010
P=2011
37=produced in the 37th week
Also, check this thread for more date info: Help me identify these 18650 cells for more info on ID.
I just purchased 40.
