There is no reserve battery in the Titanium or Aluminum PowerBooks. There is 
a PRAM or Clock battery way inside that would require disassembly to replace. 
However that lasts a long time and is not a user replaceable item. That 
should have nothing to do with your main battery failing to supply enough 
power.

Battery capacity depends upon age and use. If you have it more than a year, 
it could be at the end of its life. Sometimes they get uncalibrated which 
makes them appear to discharge faster than they should. You can recalibrate 
it by allowing it to completely discharge with the PowerBook on and unplugged 
from the power adapter so that it shuts itself down. Then charge it fully. If 
it then does not last more than a brief amount of time, then it is likely 
kaput. If it is still pretty new (a few months or so) you may be able to get 
warranty or Applecare replacement.
