One thing I noted with the replacement battery - from AussieBattery here in Australia; not from iFixit - but the same problem might occur; is that the cable on the new battery had to be 'tamed' (bent here & there like on the old battery, before I could reseat the screws and even the battery itself. One again the black - pointy & flat ended - spudgers, that we use in desktop iMacs, were helpful in getting under that battery and releasing it from sticky-!&&*! I used a pair of '2.5' reading glasses for this job, but '3.0' might have been better, as those screws are INFINITESIMALLY small!!!!! :(

I really wonder about the wisdom, and risk, of removing this upper plate in step 14 - unless I missed it, those three cables are NOT connected to the battery in anyway - and the chances for stuffing up said cables re-assembly are moderate to high! I can see that one would have to be careful taking that bracket and disconnecting those three cables ( I certainly was), but it looks to me like there's a case for just undoing the battery bracket & screws and carefully - very carefully - with great patience and some good spudgers, esp the black ones we use in desktop iMacs, - flat one end; pointy the other - plus the usual blue plastic ones and even a guitar pick - prying the battery out from its hideyhole! Much less stress regarding the upper bracket and the three cables while only a bit more stress over releasing the battery from its sticky grip! Anywho, I might have to stand corrected - but next time I'll go for this abreviated method. :)

If you do this - don't you still need to apply a fresh coat of thermal paste to the exposed ends of the two heat-sink posts (that separate when you open a G4 flatpanel this far) - my understanding was that the machine would overheat and you'd be left with didley squat!!
