Yes, that helps. However, the best result is probably going to be using a temperature compensated low drop out voltage regulator and a resistor. If he can get a 2.5V LDO, for example, he could use a small resistor to the LED and have practically constant current as the battery voltage decays.

I had thought I had been told that a \'funny\' thing is a thing of a
goodness. It isn\'t. Not ever is it funny to the person it happens to.
Like that sheriff without his pants. The goodness is in the laughing
itself. I grok it is a bravery . . . and a sharing against pain and
sorrow and defeat.
