At the end of the article, he admits that the cells don’t work after 2 years claiming he needs to reset something.
2 years is a reasonable life for cells. My 2004 Powerbook G4 is on it’s 3rd battery. I should see if I can find one of the old ones and break it open.
I do also have a Powerbook G3 (Wallstreet) with a dead battery but it has some other major issues (like overheating and crashing after 20 minutes and being too slow to run OSX), so I don’t think I’ll bother trying to replace the cells.
The cells in question were the Li-ion type of the 18650 variety, which is a very common lithium ion cell (18mm diameter, 650mm length) for laptops and other devices with large packs. There is a size, 14500, which is very similar in size to AA but still it’s not called AA, and that wasn’t used here.
Don’t laptop batteries have counter-measures to prevent changing the batteries yourself?
I’ve heard of ID circuits that shut down power permanently once they’ve been disconnected.
Hello! I just replaced the cells for my battery. After facing fear and getting some help in the way, it all seems fine. Though I would like how to reset the battery counter in OSX Tiger or would it be the same as in the OS9?
Now my computer is showing 0% and trying to figure out how much battery time is left….but is not shutting down…which makes me think the replacement worked fine.
Thanks!
