G4 Powerbook new battery charging - not !

Message #1 - Posted 2007/07/01 - JohnB

Whilst clearing out my old laptop bag I found my long lost new battery for my 12" G4 Powerbook - which I got at the same time as the book but have never even took it out of the plastic bag. As the current battery in the machine is getting a bit "tired" (runs down very very quickly from 30% ->0%) I thought i'd give it a go.

Anyway I put it in and fired up. Had to reset the date from 1/1/1970. The charging light is perpetually green and after 30 mins it was still showing 0% charge. Anyway switched off, put the old one back in and the charger is glowing orange and the battery is beginning to top up as normal.

So, have I missed some trick (PMU?) or is it likely that the "new" battery is goosed?

Regards

Probably the latter. "New" batteries will die if you don't use them for a long time.

Sometimes you have to calibrate the newer battery. This can take several charging attempts (or could be ok after the first try). Also as the prior answer stated,
the Battery could be stale and cell damage may have occurred. Regards

Thanks chaps - I guess i'll try a couple more times and if it still refuses to charge - it'll go to the great recycling site in the sky. --

I've always wanted to try dismantling and fitting new cells. In fact, I've got one here ready for when I can pluck up the courage. If you wanted to have a crack at it and report back....

Well, if you do decide to get rid of the old one I may be tempted sooner or later to give it a try.

It lives !! On the 3d insert charger went orange and it started charging ! Just made 100% now so running it down to see how long it gets.

Good news indeed. I'll try a reset with the one I have here and see what happens.

Yep - reminded me of starting a car after leaving it for a month or 2. Finally spluttered into life and now after a good run out is running sweetly.

Battery is lasting >3 hours and there is a "smooth" run down of power with no precipitous decline in the last third.

It seems to have worked. The battery now seems to hold a charge; not a big one, around 90 minutes, but at least that's usable as a spare.
