Store at about 50% charge in the coldest place you can find. Warm to
room temperatures before using.
Cool. Cold is better, but don't freeze. Optionally store in sealed
plastic bag to prevent condensation when removed from fridge.
"coldest place you can find" versus "don't freeze".
Which is it?
The coldest place you can find that doesn't freeze the battery. I
would think you could decode that from what I wrote. Freezing is 0C
so anything between that and somewhat below room temperature is a good
target.
The fridge at 5 to 8C is about as cold as I would think necessary. Any
colder runs the risk of freezing the battery. If that's too
difficult, room temperature is fine. Just don't let the battery get
hot.
Before using the battery, let it warm up to room temperature.
