Cooling down batteries literally saps their charge. Because there’s less energy in the battery. You can gently warm up batteries to give them some extra charge.
The internet says that’s not true (edit: at least for alkaline batteries, but for LiPo batteries I think you’re right). It sounds like condensation is the main issue, so theoretically you might get a slight improvement if you put them in the fridge inside a plastic bag along with some desiccant.
Batteries.
I read that in the 90s and having burned through thousands of batteries to power my Gameboy, i would have done anything to get more juice.
You could have literally told me that kissing the battery before you tuck it into the Gameboy slot gave 3% more juice and I would have did it.
This reminded me of another one that probably nobody does anymore: photographic film rolls.
