Since i achieve about 2 hours on my TiBook G4 400 with a 2 year old 
battery in 10.1.5 i sould say your battery is going bad. With a volt 
meter and a high wattage resistor setup one could do a drain test on a 
battery (like mechanics do on car batteries) . This way one should be 
able to tell what condition the battery is in.  If someone you know has 
a tibook and you can try their battery for one cycle that would be one 
indicator. Im sure you would get at least 2 hours use out of a new 
battery.  The only reason you would not is if it is not getting charged 
properly or you have some kind of short.
