Query: Marked "Not for Retail Trade"

I should've read other reviews stating that batteries come repacked in a plain cardboard box, despite the picture showing a sealed retail package. They're also each clearly marked as "Not for Retail Trade"; which I believe means they aren't supposed to be sold in the manner which they are being sold on Amazon. Now, they may be fine and work as expected, but I have some doubts as to whether they may have been already partially used or originally installed in other equipment. Trouble is, I usually use lithium batteries like these in applications where I don't want to take a chance that they're anything less than 100%. Don't think I'll completely trust them in situations (such as in my underwater camera equipment) where I can't change the batteries immediately if they do prematurely fail.
