Touching on this point again, there are times when this is kinda OK. I have a Eton FR150 radio I use as a backup weather radio. It has a little solar panel on the top in addition to its other power sources. I have found that the few hours of sunlight per day it gets sitting in a window is adequate to provide a maintenance charge to keep the battery healthy, which beats having to pull it out and crank it every couple months.
