What a POS...I left it in the window for almost two full days, and when I grabbed it and pushed the button, I got that characteristic "dead battery" behaviour of the light bulb starting at maybe 70%, then dropping off to 0% within 5 seconds or so.

Guess I'll leave it in the window for a week now (until sunset next Friday), and see what happens.
