Any ideas? I don't know what to try next. My cheapo multimeter seems to be dead also, so I'll have to get out and get something to tell battery status

A second thought is to jump start the car, then have the battery tested at a car parts store like AutoZone, Advance, etc. They will test your charging system at no cost.

I agree that the battery could be bad and I would remove it and have it tested first. Let's rule out easy stuff first. I always liked the KISS Principle (Keep It Simple, Stupid). If the battery is good, check the connections off of the battery to where they terminate. There could be corrosion there which could be the issue. I would also look at the terminals that connect to the battery themselves. Make sure both ends are clean including what they connect to. The battery posts should be cleaned with a terminal tool or just sandpaper will do well. Most people just look for the fluffy corrosion that shows up, but they can develop just a film that is hard to see but can effectively block the flow of power. I learned about this the hard way many years ago when I car I had just stopped dead. That's all that the problem was.
As far as discharging the battery sitting, this is usually caused by something draining the battery which shouldn't be. A stuck relay is often the culprit. If you get to this diagnostic, I can walk you through a way to see which circuit is the culprit. All you need is a multimeter and some time. It is a time consuming process, but reasonably accurate.
