By January, we may have a 55 C (100 f) difference between indoor and outdoor temperatures. I don't know of any juice that will manage not to leak with the pressure differential created as the air in the tank warms. Then again, you don't get much in the way of battery performance at -33 C.
Note to anyone who experiences freezing temperatures and doesn't want to blow their face off: Never ever charge a cold battery, especially one below 0 C.
