I've no idea what the self discharge of these things is, but it will
be much less than 25uA, so it sounds like a useful thing to do.

I suppose I could just charge it up to 5v and see how long it takes to
drop to the 3v V_min of the IC.

Yes, nothing like a good experiment, after all it may be duff. Make
sure your meter doesn't load it too much, and be aware that it'll
probably discharge more quickly at higher temperatures.
