You need to find better resources to read. As was said, fully charged batteries are fine to at least 0°F.

More like fine to below -40F. Many a time I've had a vehicle outside with temps at -40F/C and a reasonably charge battery won't freeze. In fact I've even started my duramax diesel w/o the block heater at -40F after the truck had stat several days/nights with temps at night below -40F. Temp was up to about -35F when I went to start it. Took a while for the glow plug light to go out, cranked slow for a few seconds then started.

don't let the battery get near discharged at low temps.
