hello all

i been looking at upgrading the hdd in my ibook g4 - specs in link below

https://everymac.com/systems/apple/ibook/spec … g4_1.42_14.html

i am aware of the ulta ata 100 and old 2.5 ide connection

i read somewhere that 100gb hdd is the max it goes to

i was wondering if that is true or can use any size from any brand as long as it uses ulta ata 100 and 2.5 ide connection

and also looking to replace the battery as the one it came with is dead and doesn't hold the charge anymore (not surprised) but what recommendations is there to replace it with a third party one
