Really good to know, so let the batteries get to room temperature before charging. Gives me another reason to come home from work to get the goodies.

Anything above 32deg F/0 deg C _should_ be well and safe.
Feel free to stop reading before this line.. Science Content Follows
There is a polymer between the anode and cathode of the cell. It's what keeps them from shorting out. Thermal Runaway (aka fire/explosive fire) is caused by a breakdown in the polymer. This can happen through jarring or over charging (causing too much expansion in the cathode), heating, or cooling. Over discharging causes contraction which has the same effect.
Anywho, freezing them then jarring them can crack the polymer (or these days, thanks to Matsusita, the polymer/ceramic...) and introduce the anode and cathode. The jarring can be mechanical, or it can be electrical (ie. putting charge-power to the cell)
Any tiny hairline fractures can, over time, spread causing the short. As the density goes up (by introducing more electro-chemical component), the insulation goes down [predictably]. So as battery demands progress the risks go up. There is technology to help limit this (such as the non-conductive metallic ceramic components), but it's still a tremendous risk.
So the upshot is: Never freeze a Li* battery if you can help it. And if you can't help it (such as in the mail box), then be as gentle (mechanically and electrically) with it as possible, letting it slowly come back to equilibrium (room temp).

Discussing Florida while we're freezing in Mn is not nice, we're 30 degrees below with wind chill right now.
wow after looking around i feel much happier about the 32 ive been complaining about all day .... lol
We all make choices in life,I chose not to freeze.We should be happy wherever we are.
Hey Steve!
I live in Fort Lauderdale! If you want to PM me, my husband and I would love to take you to dinner or for drinks! You will enjoy our warm weather and ocean breezes....

Oh boy, I'm going to have to call Minnesota and warn my family member about the freezing and the battery. I got her a kit for Christmas!
She said she doesn't get much vapor when she vapes outside in the cold, does anyone else see this?
And just to rub it in, it was a balmy 70 here today! I'm loving never needing to shovel snow!

About the vape and the cold, I can test it out next weekend when I am in fricken FARGO North Dakota. Although I do not plan to spend much time outside, just running very fast from car to door/ door to car etc. I will take the plunge and do a little vape test to compare while my cousins are outside smoking.
Come to think of it, it might be hard to tell with your breath already being a cloud of white?
Fargo is only about an hour from us, our weather is cold, but no blizzard right now. Have a great visit. Will you be right in town? My daughter lives by Sabin, but in the country.
Yeah I will be right in Fargo, I forget the name of the hotel. My cousin just got married in Hawaii but is having the family reception in Fargo where he and his new bride live. Most of my Family is in North Dakota. I was born there and lived there and in South Dakota for 14 years. Since I moved to Virginia 18 years ago I find I cannot take the winters "back home" anymore.
I get off the plane and freeze, then stay chilled to the bone until I leave
Chances are since I will be there next weekend the weather will be terrible, it always works out that way for me on my winter trips.
AH Chitown winters! Bone Chillin! I love it! Hibernatin, snowboardin, nice fires, cozy nights in when Im home, the change of seasons to make you appreciate the other seasons! I dont like driving in it when you are in a hurry and when it is all grey and gloom, but you have to find a way to appreciate where you are. Im not leaving and Im a chicago boy CUB FAN, BUD MAN, BEARS FAN! I know that might not be popular but you have to stick by your love and beliefs when they are going good or bad!
When I was living there (Dakotas) the winters didn't faze me. When I moved away was when I couldn't stand Dakota winters anymore. Still a Vikings, and Twins fan
.One winter when I was 11, we had no school because it was -80 (SERIOUSLY) windchill. My parents were at work and I was home with my older sister. I accidentally started a grease fire and did some major damage to our kitchen. My sister and I were freezing outside in our PJ's as we waited for the fire trucks. Now THAT was a very bad day.
When I was living in Minnesota we had an eighty below windchill night and I had to drive 25 miles to work at night. Had the best antifreeze mix possible in the car but it still froze solid while I was driving it. The cardboard in the front grill had fallen out. Took three days to defrost my car, if I had known then what I know now I would have just parked it out of the wind and kept it idling.
I was very very lucky that someone I knew stopped and picked me up in just a couple minutes. This was on a back road and very late at night and I had no cell phone.
I'm so glad I live in Florida now!

Those wind chills can be a *****! Really glad someone found you, that could have been fatal!
Someone else mentioned South Dakota! I'm still living here, and it's... um... cold.
Sounds like I'm here for at least one more winter, too...

Yep, I lived in Sioux Falls for quite a long time.
