Default What is the shelf life of common adhesives?

Re-read Phils post -- he did not mention refrigeration "not working". He said the replacement tubes were "so old".

....
I also refrigerate batteries, and I've got some Panasonic industrial C cells that are still at full cell voltage after more than 10 years.


I had some EverReady and Duracell AA batteries from 1980 that still
seemed fully charged in 2006 (voltage reading of 3.67 over 3 cells in
series) - found when I unpacked a group of new old stock pinball and
video arcade games that used them for the battery backup. Some batteries
had leakage, but not many. I should still have those batteries around
here somewhere...so 26 years (1980 to 2006) wasn't bad, if I find them
I'll see if they still hold up after 38 years.

Photo of testing the batteries in 2006:

These batteries were not refrigerated by the way - sitting in a (50F to
80F depending on time of year) warehouse in downtown Vancouver, BC for
most of their life.
