Future best practices for me will be 1) to take the battery out if the camera will be parked for a while; 2) every few months give the shutter some exercise if it hasn't been used lately; 3) avoid lithium.

From this experience, I now gather that super fresh lithiums are probably okay, but they can fall off precipitously if not used for a while, and the battery indicator will give the OK signal even though you're in the danger zone.
