My last purchase was the 2005 14" iBook. This came with a dead aftermarket battery. I filched a spare Apple battery from a dead iBook. SysProfiler shows it has about 2300mAh left of its original 4400mAh. The charging cable turns orange when I have the battery in, SysProfiler insists it isn't charging but an old X-Charge utility indicates that it is trickle charging. However, apart from a brief period when it registered up to 3% charged, the battery refuses to rise above 0%. I have left it on overnight, both sleeping and switched off. This has resulted in no change in charge level. The LED on the battery flashes on the first LED when the charge level button is pressed but switches off after a couple of seconds. I have reset nvram, reset the PMU/SMC and done all the usual tricks but I can't get the battery to start charging. The orange LED on the charger cable gives me some hope that the battery can be coaxed to spring into life. Is there anything else left to try or do I have two duff batteries?
