Mine came with the cables for that solar hook up dragging on the ground... they "fixed" it at General RV by stuffing them into the battery box... so no they were not hooked up to battery, still are not as I didn't bother to put them on myself....could they hook to a battery tender that fits that plug? Sure, but as was mentioned, you'd want to see where they were hooked up to or NOT hooked up to... hate to find out they are lying on metal and then hook them to the battery posts...
