It had got to the point where it would only give me about 25mins on battery, even after being plugged in all night. Over the past few months my PowerBook G3 Firewire's battery has been holding less and less charge. 'I have seen the evils of procrastination, and I vow to change my ways tomorrow.' Apparently, they know that their batteries have an extremely low shelf life, and are hoping to make some extra $$ off of replacement batteries.

As it is, Apple only supports and warranties their batteries for up to a year, even if you buy the 3-year Applecare protection package. They also let me know that if I had called any later, they wouldn't have been willing to send me the new battery.

After I had told them that told them that I had tried the typical tricks (complete drain to recalibrate, resetting power manager, etc.), they offerred to send me a new battery free of charge.

I finally decided to give Apple tech support a call. For the last couple months, I had a similar problem that someone here posted: once my battery dropped to about 80%, it would instantly plunge to 0%. To put it succinctly, I am incredibly happy that I bought the Applecare protection package, when I bought my dual USB iBook last July. * Reboot into OS 9 and cycle battery (discharge completely, then recharge)ДЄfter reading all these tales of dead batteries and experiencing a few tales of my own, I feel compelled to add my two cents (or my tale). In summary - if all else fails including the nvram solution - try this: I have yet to try that technique yet though. According to the author - it is the menu that crashes and takes down the PMU (that controls power management and charging) with it. One thing I have not tried that one of the submissions at Macintouch mention - was disabling the Battery menu extra. So the solution listed partially worked for me. First I got about an hour out of it, then the next recharge it returned to its old habits of 15 mins, die at 80%. So I rebooted into OS X and it appeared to be working. Now the big test - will it stick in OS X. it ran for 1.5 hours (with no activity on it, but hey its an improvement. So I plugged it in and let it charge in OS 9 for several hours. So I reset the nvram, then booted off OS 9 CD and pulled the plug. The process said to reset the nvram (as explained in this article) then reboot to OS 9 and cycle the battery. I have long since 86'd OS 9 on my iBook so I had to pull out an old OS 9 boot cd. Well I decided to give it the ol' 'Try # 378' - rebooting into OS 9. So I read the article again and noticed one persons comments about using OS 9 was the trick on REALLY stubborn machines. Tried the nvram rest, let it charge overnight - tried it. I finally decided the battery had just lived its life and was depleted, even though I have rarely even used the battery.ДЄfter reading the Macintouch article last week - I decided to give it one more go. I tried everything including the nvram techniques and nothing worked. It would charge fine, but when it got to about 80% it would drop instantly to 0%. I have an iBook 2001 (late, dual usb) that has been giving me problems for the last 3-4 months. Good luck with your (hopefully) repaired PB! I still don't know why a crap battery can do this at these settings, but for me this was definitely the cause and effect.

It turned from full to empty within an hour - wich I never noticed before as I mostly used the Power supply. I now believe my battery is dead and has to be retired. I found out that it started working normally after I set the Energy Saver Settings to Highest Performance.Д«ut setting the Energy Saver Prefs to Longest battery kills it instantly and leaves only a way out via forced restart. Tears, Screaming, nothing helped, I saw visions of ruined Logicboards etc.Д«ut then. I reset and zapped whatever was possible but nothing worked. I had nearly the same thing with my iBook Dual USB, in my case it would freeze as soon as the powerplug was pulled, rendering it a non-portable laptop.
