Battery mystery resolved, perhaps

I think what's happening with the recurrently-draining car battery is that the trunk lid latch has worked itself loose from its solid moorings. That means that, while it closes, it's not as tight as it should be and the sensor which tells the trunk light to turn on is continually tripped. Over time that's enough electrical use to eventually take the battery charge down.

We'll find out. I have an appointment tomorrow morning at a body shop to have them repair it. I hope I'm right.

Great! How'd you find that loose latch sensor issue?

I tried to think what electrical widget might be left on when I turned the engine off, and realized I'd been having trouble shutting the trunk lid. I rarely drive at night and even more rarely have occasion to open the trunk at night, so I had to look to see if there even was a trunk light. There is. Then somebody suggested I touch the bulb to see if it was hot, and it was, even though the trunk hadn't been open. Therefore it was getting electricity when it shouldn't.
