A Matter of Balance
Marker lights, by design, need to float upright for maximum visibility. The 6-volt lantern batteries provide the ballast for these lights. Although batteries may be the same size, the different chemistries cause them to have varying weights. It is imperative that only the 6-volt battery models suggested are used. Too little ballast and the light will lie over on its side and be ineffective; too much weight and the light may sink. If there are any doubts as to the appropriate weight of the battery, test the light by placing it in shallow water. If it floats upright, it is good, however, if the SM-2 sinks, the battery is too heavy.
