There are only six or seven companies that make alkaline batteries in the whole world. (Nobody can prove how many factories in China.) All the different brands contract with the same six or seven companies which just manufacture them with the contracted brand labels. Some are very slightly better than others, but there's not much variation in a standard "alkaline battery".
The batteryshowdown site is a British site, so they have some varieties only available in England, and what is listed there may not be the exact same battery as available in US with the same brand type. That is, something branded one way in England may, for the US market, be manufactured by a different company.
Even Duracell, which does make its own alkalines, contracted their brand label to be put on certain batteries manufactured by Panasonic/Sanyo - the first runs of "Duracell Pre-Charged" were really Sanyo Eneloops. At least.
For a time, "Kodak" branded alkaline batteries in US were absolutely positively made by or contracted from Panasonic, and Sanyo made them for Panasonic (Panasonic owns Sanyo). I know this for a fact. But that does not necessarily mean that THESE batteries on woot were made by Panasonic. Kodak may have changed suppliers.
It is my GUESS that woot, and Kodak, is here blowing out "Kodak" batteries that Kodak contracted before Kodak's reorganization. They are more likely newer than older. Kodak has been selling off anything they can as fast as they can for a few years, and they probably contracted a few years ago to receive a steady supply of these batteries for a few years. These are probably fresh off the boat or only a month or two older than that. If they were older stock, Kodak would have dumped them to woot and others sooner. They have done this several times in the past year or two. Kodak has to move these and get some money back fast as the boats come in. Again this is a GUESS.
So consider all this just some odd historical trivia and trade secrets, but I can't tell you what these specific batteries are. But being "Kodak", I expect they're OK. Whatever else Kodak did to itself, they never sold junk.
