Your first instinct is to call for help if you’re ever in trouble. However, low temperatures drain the life out of batteries a lot quicker. Always have a plug-in unit or a hand-crank charger in your vehicle. If your car battery dies, which is a realistic assumption in the winter, the charger won't work. Keep a portable charger and leave it there.
