Label the picture CR2354A and CR2354B.  Message the seller before buying.  If people do it often enough, then they might show it clearly.

Open it at the checkout counter.  Tell them you need to buy the correct version.

Sure, or you tear the card stock off the back.  These were encapsulated in the plastic.  I couldn't see very well when I was doing this in dim light.  I thought they had glued the batteries to the plastic, or maybe the package was formed around them when the plastic was molded.  Then I finally caught a glimpse of the plastic bending all the way around the battery.  It was also shaped oddly,  which would be hard to explain, but that made it appear to be loose around the edges and only attached at the top of the battery.  I had to rummage around for scissors, as I was not in my place. 

Why is scissors plural?  Why are pants plural?  Does anyone wear a pant?  This must come from something having to do with how they are made, to pant legs making pants or something.  Scissors is probably like that to, since you need two edges to shear one against the other.

pants used to be two separate legs so you needed a pair of them, in Danish you can use the words for pants in singular

The Danish dictionary claims that the Danish word for scissors (that is now only used in singular) came from the name of single edged sword

The lip-equipped one is an old (Renata? Varta ?)design; later ones were made in the far east, in thick-coin fashion,
(Panasonic) or that was the case for CR2450 (not sure what 2345 means).
Many early instruments  had sockets that were form-fit for the old two-diameters 
construction.   I had a Starrett micrometer like that...
