A watertight battery box comprises an upwardly open base and a downwardly open lid which rests on the upper edges of the base. One edge of the base has a recess therein for receiving the battery cables, and the lid has a downwardly opening channel therein for receiving the cables. In use, water can rise around the battery box without entering the battery box, because the lid traps air beneath itself but has little or no buoyancy.
