Depends what you are doing with it and how it is set up: More Ram means longer battery life as the Mac will need to use the HD less for swap space Using the CD/DVD drive will lower battery life LOTS as will accessing the HD lots. I can happily watch a 2hr dvd on my Al or Ti before the battery warning comes up with apple batteries and better with Other World Batteries > And which PB do you have?

I have multiple batteries for long haul flights and swap them out then, but I have found no great advantage in swapping them out regularly. I have apple batteries and other world batteries for my Ti which give an amazing boost to battery time. On the Ti about 30 to 40 minutes and about 20 to 30 minutes on the Al longer than the apple batteries! http://eshop.macsales.com/shop/powerbook/batteries/ Alex
