A $40 Battery Tender is simpler. Here in Minnesota, seasonal rolling stock is the norm. I have boats, quads, motorcycles, cars, and mowers on these things all winter. In the spring, I take 'em off and put on the snowmobiles and snowblowers.
A discharged battery (less than 80% charge) will not only short the plates due to sulfation (decreased battery life), it will also freeze. A charged battery won't freeze until about -56 degrees. That's sufficient, even in Minnesota.
