Tip: New batteries can dramatically increase iBook life
A post on Apple's Discussion boards by Benjamin Weaver indicates that the new 12" G4 iBook battery (part #M9337) has delivered dramatically increased uptime for his older 600 MHz iBook.
"I only installed the new battery after a clean install of Panther 10.3.1 (and resetting the power manager). I was amazed by the results: After calibrating and using the iBook for a few days, I regularly get 5 hours of time on my usual settings (Energy saver set to Automatic, screen dimmed down halfway and Airport on). And 5 hours are also what I get out of it, even when using the screen at full brightness and doing some Photoshop work during that time. [...] (The old battery lasted about 2.5 hours)."
According to Apple's documentation, the 50 watt-hour battery in the 12.1-inch display G4 iBook model uses six lithium ion cells and provides up to 6 hours of operation, depending on configuration and usage.
The newer-model battery is compatible only with 12-inch iBook having two USB ports, is priced at US$129, and available from the Apple Store.
Older iBook batteries will have a part number M8956 or lower.

Went from 1 1/2 hours (it was >2 years old) to 5 hours.
Seems like everyone is doing this: Apple Stores have been backordered
on 12" iBook batteries for weeks now.
So maybe if I order one now I'll have it by the time I'm ready to buy a
Mac desktop system and will want to revive my iBook's mobility beyond
~1.5 hours again. :-)
when they first came out, and that battery could go 5 hours easily. After
a couple of years, all laptop batteries do these things.
iBook G4 battery won't match the rest of your iBook exterior. The iBook
G4 has an opaque white exterior that appears lighter compared to the
older iBooks (which have a transparent exterior painted white on the
inside).

hours from my old (now backup) battery on my iBook 600. Finally I can
do more than watch one DVD on a flight!
