What Happens If You Freeze Batteries. Cold temperature increases the internal resistance and lowers the capacity. Too much stress on the batteries will then take its toll and greatly reduce the life expectancy of the battery.
Different types of batteries different chemistries are differently affected by cold some much more than others but all will lose capacity and as a general rule the colder they get the less capacity they will have. However ODYSSEY batteries will still work at temperatures well below freezing. Heres why if your battery is partially discharged the electrolyte in a lead acid battery can actually freeze.
The more the battery is charged the lower the temperature must be.

While high temperatures can kill a Li-Ion cell pretty fast I dont think -40C temperatures will do any harm to something like a laptop or cellphone battery. A freezer cannot charge a battery but it can save the charge for a longer time. Besides getting cold they lose capacity.
