Great list—and of course there is “cold” and then “really cold”.
The decline in battery functionality is worse than linear.
They don’t even test these bricks below twenty degrees.
If the circuits that protect the battery allow it to be charged when there are cells which have not reached a high enough temperature... those cells are damaged or destroyed. One damaged cell among hundreds or even thousands can cause the battery to self-destruct.
One of my hobbies is playing with small drones. Even the little batteries that I use in them can put on a spectacular show and destroy the drone. That is why you always get rid of any battery that shows signs of damage. Sometimes you notice a bulging cell, sometimes you notice that they are going dead sooner than they should, many times the primary charger that I use indicates there is a problem.
Honestly, I don't know the best way to store them -- I can't keep them out in a small shed, since NH winters get quite cold, and I heard these batteries become unstable in extreme heat or cold conditions.
Any Freeper advice would be appreciated regarding storage.... other than tossing them out. 😅
