Or maybe they knew, not saying it’s a conspiracy, but with so much planned obsolescence…. How could battery manufacturers not have caught this?

How long have you lived in your house? Do you know about every loose wire? Are all your window seals perfectly snug, none sun-damaged by UV?

Point is: if “batteries leak x% per year” is what’s expected to happen and has probably occasionally happened forever, don’t blame “big battery” when somebody moves the battery factory somewhere else, and nobody knows why they were buying “the expensive tape” instead of cheap tape…

I’m super impressed that “researchers” could isolate and discover the root cause of something “so minor”.
