In fact non-rechargable batteries are perishable as are all batteries. Just like us they have a limited lifetime. They have a shelf life and will self discharge simply sitting on the shelf. The amount of self discharge may allow an extended time on the shelf before the consumer notices the degradation. How do you measure battery life as a user. Most of us it's not measured at all but rather a gut feel as to whether you got a reasonable use time from them. And that varies widely depending on what the consumption of the device is. Many stores where we purchase batteries are air conditioned so are not stocked in excessively high temperatures, at least on the showroom floor, and depend highly on fast turnover so they mostly don't sit around long.
Batteries rechargable or not generate electrical energy by a chemical process. And if you remember your high school chemistry, one of the ways you speed up a chemical process is to add heat (ye ole bunsen burner). All that to say temperature greatly affects battery life and performance. One performance characteristic is shelf life or the ability to retain the ability to generate electrical energy before the cel is used by the consumer. Based on my understanding of the above, I for years have stored my non-rechargable cels in the refigerator. Did I measure any preformance advantage for doing so. No, of course not - who really measures? But I did it because it made sense to me. Then several years ago good ole Consumer Reports (who measures everything) did some testing and measuring to see if in fact (not just gut feel etc) battery life was extended by refrigerating them. As I recall, if it made any difference at all it was so small as not to be significant. So now where I use to store batteries, I store butter. There it does really make a difference including making it hard to spread.
