I have our HW27KS tucked inside of our garage for the winter. I have read around differing opinions about the battery, but wanted to ask anyway. Should I leave it plugged in or just disconnect the battery? I thought about plugging it in for 2-3 days at a time, then disconnecting the battery when not pluggged in. The converter has three modes that senses the load and adjusts accordingly. One of those is a slow charge. Seeing that, I may just leave it plugged in. Thoughts? This is my first winter with it and being in Georgia, my garage should not get too cold.
