As a battery get older it will take less and less of a charge. So if the battery held say, 5400 @ 100% when new, at midlife the maximum charge would be half of that at 2700. But a full charge to 100% yields only 2700 not the original 5400. To get a good idea of the status of your battery, download and run Coconut Battery: http://www.coconut-flavour.com/coconutba...

Download the 2.6.6 version for your PowerBook.
