Panasonic NCR18650B 3.6V 3400mAh (protected) is the most famous out of all 18650 batteries. When first released several years ago it was the highest-capacity 18650 cell mass produced and thus an essential ingredient in the rechargeable revolution and for the adoption of electric vehicles like the Model S (which has been powered by the Panasonic 18650B for some years). It is still the most requested cell for custom packs. A PCB protection circuit built in to this cell makes this cell perfect for low power applications like torches, the PCB prevents over discharge of the cell which can severely shorten the life of the cell.
