So now you know--start the engine if you have to play around with the
windows for a long time. If you listen to the difference in motor sound
with the engine running and with the engine off, you'll notice that the
motor sounds a lot stronger (or at least more robust) with the engine
running. This is a good clue that it's drawing a lot of juice, and is
happier when powered by the alternator. You can also turn on your
interior light and see what happens when you hit the window switch. My
guess would be that it will dim significantly with the engine off.

Anyway, 30 mins. is a very long time.
