I’m surprised that it would not work even though you kept the battery warm. I left my Ion Alpha and battery outside on the auger yesterday for three hours while I was fishing, and it stopped working even though the battery showed full charge. Once the battery warmed back up it worked normally. I have had the auger for two years now, and have always left the whole unit outside while fishing. It was a good learning experience that the battery can freeze up when it is -15 out.
