A slow death

So, I’ve figured out that my iBook’s battery is dying. I’ve tried recalibrating it (several times, in fact) with no luck and I’ve even tried resetting the PMU and that doesn’t help either. I get about 2 hours of battery life in OSX and 1 1/2 hours in Linux. When I first got it I was getting around 4 1/2 to 5 in OSX and 3 1/2 to 4 in Linux. If my battery isn’t covered under my AppleCare Protection Plan, I’ll have to use $127 from my tax returns to buy a new one. Hopefully a dying battery isn’t an act of God (see section 2.e.ii).
