I have an iBook G4 that I bought refurbished about two years ago. When I first got it, the battery would last for about six hours of average use. A few months ago, I noticed that it was only lasting four or five hours. Then, within the past month or so, it has only been lasting two or two and a half hours. I figure I will need a new battery soon. My dad said that two years of life out of one battery is pretty good, especially since it was used when I bought it. I downloaded Coconut Battery and it says I've used 314 battery cycles and my battery has 45% of its original capacity. So, within the next few months, I'll have to get a new battery. My dad sent me a link to a 'Battery Conditioner' which claims to restore an old battery to its factory capacity. It's more expensive than a new battery from the Apple store. But, it would be worth it if it actually works, since I plan on keeping my iBook for a long time. Here's a link to the 'Battery Conditioner'. Click Here! Has anyone used one of these before? Does it work? Or is it just a scam? Would it be better to buy this thing or just buy a new battery?
