In the case of the iBook G4 (and a decent number of laptops from that era), if you crack open (carefully!) the battery, you'll see that it's just a bunch of 18650 batteries spot-welded together. I ordered some decent 18650 replacement LiOn batteries, unsoldered the circuit board and the wiring, spot welded (with a cheap amazon spot welder) the batteries together in the same configuration they were connected in the original battery, soldered the wires / circuit board back on, and stuck it all back in the case and snapped it back together. There are videos of people doing this on YouTube you can watch for getting the general idea.
