Keeping Her Plugged In

During the coldest time when we are home( part Dec., Jan.,& Feb), mine is winterized and the fridge is off. My power is routed through my home breaker panel and my Progressive unit is always plugged in, so surges or brown outs are unlikely to the extreme. When I do turn the fridge on, it and the converter together only pull 3 to 6 amps. The largest benefit that I can see is to battery longivity. My first set of house batteries(Interstate Workhorse) lasted 14 years until 2012. The next set(Duracell Golf Cart) were replaced in mid last year after 5 1/2 years. I am also on only the 3rd chassis battery.

Sorry about being a doubter, but I don't buy the 20 to 30 dollar a month thing. That would be about 15 to 20 percent of my monthly bill in a total electric house.
