Is there a way to reuse an apple powerbook g4 battery to power a macbook pro? I know that it doesn't fit, but I'm hoping there is some kind of external pack that can accept and charge a powerbook battery but which can power a macbook pro. Any ideas? [more inside]

My year-old Powerbook G4 has acquired the habit of suddenly shutting off when it thinks it has no more power, which usually happens when the menubar item says the battery is around 30% full. Do I need a new battery? Or can I massage it into the proper sleeping/hibernating behavior somehow?

PotentiallyStupidQuestionFilter: I'm looking to juice up my long-in-the-tooth titanium Powerbook (from March of 2002 -- 667 mHz processor, 512 MB of RAM, 30GB harddrive, etc.) with both a new battery (since the original one now gets approx. five minutes of life when unplugged) and OS X 10.4. Here's the weird question: Should I put the battery in first, and then update the OS, or do the OS update and then swap in the new battery? It might not matter at all, but I know that operating systems do have an impact on battery performance -- is that something I should be taking into consideration, or can I do either upgrade at any time without worrying about sequence?

I upgraded my wife's powerbook (15" titanium/867Mhz, from 2003) to tiger last week and now it seems when unplugged it doesn't recognize the battery in the status monitor. I've searched google but can't find any fix. [more inside]

More Hot Powerbook Action! My Powerbook G4 seems to run especially hot since I got a new battery, a generic-ish 3rd party dealie I bought off eBay. And the power adapter just failed. Could the battery cause these troubles? If so, where should I look for proper battery replacements? [more inside]

My battery acts funny. It always says I have over three hours when it first gets charged. Then after just a few minutes it says much less, like an hour or so. Then within minutes it is off. I have charged it completely and let it drain to completely of which I have been told resets the power manager. Do I need a new battery? If I do, are any of the after market batteries better than the Apple battery? The computer is two and a half years old.
