Not forever. The battery is a 6 volt lantern battery with a two year  
shelf life. They say with a 15 minute interval the life should match  
the shelf life. Of course, a battery could well last longer than its  
shelf life, but at some point even with no drain it will fail.

Even at two years, that amount to $6 a year, not enough to break even  
the cheapest ham ;-)
