I just realised that my PowerBook battery is actually pretty good and i get 2.5/3hrs on average despite it being almost 4 yrs old (ignore the 24453 thing). Then again i've probably jinxed it now and it'll die within 24 hrs. Bleh.
My MBP Battery went from about 3+ hours to about 2 hrs when I upgraded to 10.5 when it can out. This was also about the time I hit about 200 charge cycles on the battery. The Genius said the battery was just getting near the end of it's life but the new battery I bought to replace it never quite got 3 hours of run time.
Well i bought the laptop used so credit will have to go to the original seller for the most part.
As for me nothing special, one thing i do though is never let the battery run down completely all the time. Sometimes at 25%/35% i'll plug it in. Also i don't use the laptop on battery mode EVERY time i use it, sometimes its always plugged in but at the same time i also make sure i use the battery at least 3/4 times a week to keep the juices flowing
wow thats pretty good considering my everyday 12" powerbook will only suffice a 4 minute life on its battery! Thats just enough to run from my bedroom to the other power adaptor in the living room!
I cant really justify buying a new battery now as Ive been used to surviving off the power charger for long enough now. Its like having a desktop you can put to sleep and move around. A sort of portable desktop!
