Warning: heating earbuds batteries to over 300F also causes fires

      IIRC freezing accelerates the chemical degradation of lithium ion (especially if you attempt to charge the battery at the same time) and tends to lower both the voltage and amperage of most battery chemistries, but it seems plausible that this might

      1. temporarily defeat a cell protection circuit, allowing a charging procedure to initialize, or
      2. delay a thermal failsafe cut-off of a damaged cell long enough to boot or charge a device

      Regardless, for those tuning in at home, best to keep your batteries out of the freezer, especially lithium types, unless spicy pillows are what you’re after.

        Oh, sorry, since we were talking about the good ol’ days I thought it was implicit I wasn’t talking about lithium batteries

          Ah! Yeah it’s been a while but I seem to recall seeing alkaline batteries in a some freezers or refrigerators sometimes when I was a kid, along with other curiosities like rolls of film. No one ever explained why.

            Oh right, those were stored in the fridge… weird to think about it.
