"I bought this charger to maintain the battery on our pontoon boat that only sees sporadic use throughout the summer at our lake house. Usually I have to string a long extension cord and charge the battery with my plug-in charger at least once during the summer. With this charger, my boat's battery was always at full charge and I never had to hook up the plug-in charger ... DEFINITELY money well spent. I noticed my boat dealer was offering this same charger for about twice the price that Northern Tool charges ... another benefit."
