Battery and Cold Weather

[Madmax07]

This is the first year we will be making the trip to Arizona with our Montana in late December. Normally, I would take the battery out for the winter and put it on a battery tender in my house. Since we will be leaving in about 6 weeks I would prefer to leave it in.

Winter temperatures in our parts can be quite severe. Temperature could potentially drop down to -25 or -30C. I currently have the trailer plugged into shore power which should keep the battery charged. Will I be okay with this, considering the cold weather or should I bring the battery in the house until I leave and just leave the trailer connected to shore power?



Thanks
