You should fully discharge NiMh and NiCad batteries before recharging: they are prone to the "memory effect" if not fully discharged. More than likely, many of the people whose iPod batteries "died" after a year or less of use probably recharged it too often without letting it run all the way down. Yes, that is the proper way to use a rechargable battery. I know an increase of roughly 240 mAh isn't much, but its an increase nonetheless. I don't know if this is some strange fluke or not, but has anyone else witnessed anything simiilar to this? I will also add that my battery is and was properly calibrated for all of this.

During this 2 week period I kept watch on the Full Charge Capacity (mAh) in system profiler, and watched it slowly creep up to 4520 mAh.
At the end of the 2 week cycle, my battery's max mAh had increased from 4280 to around 4520. For example, I would charge my battery till it was 100%, then unplug it and use it or let it sleep until the percentage was around 85%, and then I would let it recharge to 100%. Then, for the next 2 weeks, I never let the battery level drain below 85%. This keeps the battery juices flowing." This is when I decided I was going to try something. I then read Apple's battery page and on this page is stated, "An ideal use would be a commuter who uses her on the train, then plugs it in at the office to charge. At this point I've only had the powerbook for a week and decided I want to get the most battery life out of my machine. So that made me check mine, and I saw that my battery's max charge was somewhere near the 4280 mAh area (after installing the battery update). One of these updates was a battery update, so I read into it and found somewhere that the updater was supposed to increase the battery's max mAh from 4400 to 4600.

When I first got the machine, I ran the software updater and installed all the updates. I'd save your money for a new system.To start off, I have the latest rev.

While you could install another logic board, it would be used.
If that's the case, then I'd recommend that you continue to use the Powerbook as a wall-tethered system, until you can afford a new system. Now, if you replace the battery, and the new battery will not charge, then you likely have a logic board problem.
Scroll down and choose your model 15" or 17". If you want/need a working battery, you might try this one, which I've used in several of our Powerbooks. It sounds like you can run under power when the power adapter is plugged in. Was this last battery you bought an Apple, ebay, or other brand battery? Typically, the battery stops working about this time too. For example, on yours, it says there is still some capacity left (2202mAh) but the cycle count is zero (cycle count should be in the 200 to 400 range). One of the signs of a failing or dead battery is when the battery stats have screwy numbers. Looking at those battery stats, your battery is toast.

I have a Powerbook 1.5 GHz PowerPC G4, with Mac OSX 10.5. I know I am overdue to get a new computer, but being a recent grad has complicated the situation a bit so I would be very grateful if anyone has any pointers to get my old laptop a couple more months of useful life. The light turns green for a few seconds when I restart, but then turn orange again.
I haven't had this problem for about a year, but now I don't know what else to do. That one gave up too, so I replaced it again (and the chord). My battery was among the ones recalled, I replaced it. It happened like a wee or so ago, I reset the PMU and it started charging again, then it stopped charging oncemore. That time the PRAM/PMU reset worked, but this time it doesn't. The battery on my Powerbook G4 is not charging.
