Does one just wait for the meter to stop working on the 'M'-bodies?
On my MX, when the battery finally started to go, the over-exposure LEDs on the meter stopped lighting up when there was over-exposure. At first I thought there was something seriously wrong with the meter, but then realized that the batteries were just done. In any event, new batteries fixed the problem!
At least, that's what mine did. YMMV and all that. If there's a battery test mode on it, that'd be nice, though I can't say I remember reading about one in the manual.
