What's inside an iBook battery?

[NewbiePPC]

Sorry to revive such old thread.
I would like to test this procedure to revive two batteries that were left too long without charge

Does anyone where is the + and - on the powerbook g4 battery connector?

SOLVED: Need battery pinout for A1057 (PowerBook_G4_1.67_A1107) - PowerBook G4 Aluminum 17" 1-1.67 GHz

J25 connector`s 2,3, 4, 5, 6, 7 corresponds to Battery connector`s P1(closer to the corner of the battery), B2, B3, B4, B5, B6(far from the corner of the battery). So P1 = BATTERY + B2 = ⏚ B3 = BATT_CLC B4 = BATT_DATA B5 = PMU_BATT_DET_L B6 = BATTERY - I also used electrical tester to check...
