Study the ATmega.da sheet to learn how to put the AVR into sleep mode and only wake it when needed. It continues to operate at very low current in sleep mode. Also, LCD can operate with virually no current if you get the right one and drive it properly.

Progress! I pulled the smaller LCD off and tried the button batteries again, 2x CR2032, wired in series to provide 6V. Success! I also pulled the other LCD off and tested the small one alone with buttons. Success!
Now I'm testing how long it can stay on continually. They're draining fast, relative to the other batteries, but it's a good test, even if it will never be used like this.
As it turns out, I do have a multimeter where I can measure current usage. I'll post back when I have some data.
Thanks, Joe. Sometimes it just helps to talk it out loud with someone, because putting it to words focuses the mind.
