From electrical storms to hurricanes to tornadoes to earthquakes and even to the most chaotic of ham radio activities, Field Day, emergency power and the amateur radio service are bound together. However gasoline generators, windmills and solar panels, although impressive, are no more essential than the lowly battery. Deep cycle and gel-cell batteries are usually indispensable when putting together an effective emergency power system.
