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.


only if the battery uses pure water as it's electrolyte.


Sigh... I guess I have to do the necessary Google searching.

Many authors suggest that freezing Li-ion batteries may be
detrimental. However, most Li-ion battery electrolytes freeze
at approximately -40 ?C. Household freezers rarely reach below


Thanks you for verifying that the phrase "freezing is 0C" was complete
bull****.
