For care instructions, follow whatever SMC says to do really. Danny is the main importer of the cell and works closely with IB in testing and development of the cell. In my opinion, he knows the batteries better than anyone in the business, not mention the countless national titles won by SMC over the few years...
And the label actually has SHV printed on it, by IB.....if your 4200 don't have SHV on them, they clearly are just regular 4200 cells....
