Thank you, very very instructive - but why on Earth

does Apple not mark the battry holder on this model

with + and - ? ? Now, thanks to your close-up photo

I found out which way to turn the battery. (I hope)

Best regards

Agreed - slot should be marked with + and – . . .

Thanks for the clear and sharp photos d;-)

This is not valid for the late 2005 model of G5…Model 11,2.

It uses a coin shaped Panasonic Lithium battery. I just ordered one from OWC.
