Is this even possible?
Has anyone else tried it out?
QUOTED:
"Wary of what 10.2.8 seemed to do to batteries, I only installed the new battery after a clean install of Panther 10.3.1 (and resetting the power manager). I was amazed by the results: After calibrating and using the iBook for a few days, I regularly get 5 hrs of time on my usual settings (Energy saver set to Automatic, screen dimmed down halfway and Airport on). And 5 hours are also what I get out of it, even when using the screen at full brightness and doing some Photoshop work during that timeframe.
