      I’m not sure if it’s still true with technical advancements (probably not), but it used to be that rechargeable batteries were put in the fridge, because they didn’t loose charge as much in cooler temperatures.

      Many thinks old people do used to be useful but were made redundant with development over time.

        Funny thing is years ago (like 20+) I use to put my spare batteries in the freezer, but then i learned that doing that would cause alkaline batteries to loose charge faster over time…not recall where I hear that, or if it is even true (I vaguely recall looking it up on the “early” internet)…but to this day i no longer do that…I keep them in the non-temp controlled garage…because that makes so much more sense right lol 😅
