I ran across this on another compuer site, and thought that us iBook owners might learn a thing or two on how to care for the batteries in our iBooks. I personally already had a battery failure about 1.5 years from when I bought my iBook, though the battery could have been slightly, or considerably, older. The information in this article could explain partially why our batteries seem to be dying all at the same time. http://en2.wikipedia.org/wiki/Lithium_ion_battery Al
