After doing a search on this site about white powder by a battery post, I came upon this from the FAQ:
----------------------
"It is the nature of a battery to eat away the post seal. When it does you get the white powder. Felt washers and grease do not keep the acid from eating the seal away. The white stuff is the end result of the seal failing and efforts to remove the white powder do not cure the problem."
-----------------------
Does this mean that my battery needs to be replaced? It seems to start and run fine. The voltmeter in my car shows nominal voltage, although I'm running the original 21-year-old alternator and voltage regulator.

It's an Interstate battery, about four years old.
