iBook battery doesnt charge quickly

Hi,

I've got an iBook G4 Model and the battery literally trickle charges, as in if I leave it overnight it will charge the battery 12% more.

2 different batterys have been tried and ive replaced the DC in board but could this be the power adapter?

When its running on battery I get stats of Amperage -1038 (Assuming thats normal under usage?) and Voltage is 11531 and Cycle Count is 3 (this is the new battery in).

When the power adaptor is in the amperage only goes to 30.......I;m assuming it should be more than that to charge the battery sufficiently??

Thanks, Luke
