Ha. Don't be fooled. The only reason, and I mean ONLY is because I lost my main motor jug fishing. The next morning I needed all hands on deck for batteries to use my trolling motor to go 4 miles back up the bayou to get all my jugs. . That's where the charger was plugged in so I went on a battery hunt and brought them all there. When I got home I topped them off. Give it time and they'll be scattered to the wind again.
