Charging Lithium Batteries Cold or Room-Temp?

[Bass Thumb]

Is it better to charge lithium batteries while cold or at room-temperature?

 

For instance, when I get home from ice fishing, I let the batteries for the flashers and the electric auger warm up to room temperature inside the house before connecting them to the charger.

 

Is this necessary, or could I just plug them in while they're still ice cold from the lake?

 

Thanks, Joe

I doubt it makes a lot of difference. It'll be at room temperature in a short time and long before it's done recharging anyway. In fact, the charging process will warm it.

Thanks. I got some good answers over at IDO as well.
