That's because someone is confused, Hive. Gamefaq wants you to link to the HTML page that leads to the FAQ, not to the FAQ directly. The page that comes up when you hit that link says so, and claims that every HTML page tells you you're supposed to do that.
However, I couldn't find *ANYTHING* on the HTML page preceding the FAQ that says so. Guess they're not as smart as they think they are...
Try going
here instead, and look for the battery replacement FAQ.
