Chris - is this battery life improvement due to batteries with better  
storage capacity, to better energy management in the Powerbook, or a  
combination of the two?
I am assuming that at least the batteries are better, but is it more  
than that?

I assume that my Al-book/1st edition September 2003 battery (already  
replaced once, but getting weak now, max 1h30) could be replaced by  
the newer batteries.
I did read that 3rd party batteries were also available with greater  
capacity.

Has anyone got first-hand experience of these 3rd party batteries?
