Thanks for taking the time to explain a bit. Only time I remember Eveready, they were the old carbon zinc, and Duracells have always been alkalines. Do you mean Energizer?
I remember reading on the manufacturer web site, refrig is OK, freezer is not.
The one time I tested battery life using 2 AA mini mag. Mixed brands of alkaline AA cells, and they all lasted about the same.

This was from memory during Projects: I prefaced with the caveat in case I misremembered. Somehow the subject came up during discussions with Eveready as I was comparing to Duracell. Interestingly, in our tests, Eveready lasted about twice as long as Duracell in the same applications. Ray-O-Vac lasted around 20% longer than Eveready, but had a tendency to leak when left unattended for long periods.
The comment came more like an aside, rather than part of the Project. But the importance didn't surface until I saw the plethora of "test your batteries here" cards where they were SELLING batteries, DUH! May also been part of the discussion of whether to save your batteries in the fridge. Again, as I understand it, yes, cooler they store longer, BUT, and this was a big warning, keep them dry, else they develop paths for self-discharge and all the 'goodness' of keeping them in a fridge will be undone.
As I responded here, thought would come to me, but didn't. Don't know the origin. Can still here the phrase and the 'tone' of the comment from the vendor as he said this under his breath, "Watch out. If you plan on storing your batteries for a long time; don't ever test them. If you do, a chemical process starts that accelerates the battery's discharge and you'll shorten its shelf life from 5-10 years down to 1 year."
Perhaps, an urban myth, don't know. But I really believed it when I saw how much the battery companies started touting how you should test your battery, right now, under full load, and do it often.
