When I start My Apple IBook 133 I have to reset the time and date. I'm in the process of changing the main battery.

No Mac laptops have had a secondary battery since the first ibooks.....so if you run your battery to zero, or swap it, you lose your PRAM settings. Actually, if you do it fairly fast (I am guessing a you have a couple minutes?), there is a capacitor (http://docs.info.apple.com/article.html?artnum=58445) that holds a little juice.

Date and time are the most obvious things that will be off if power is lost.
