Im sitting here on my 12" powerbook G4 nearly coming up to its 3rd birthday! Sadly as soon as I take the power charger out I get the reserve battery warning, this kind of makes the computer unusable as a portable! However most of the new batteries I've seen around are either cheap chinese makes or very expensive! I mean a £70 battery for a machine perhaps only worth 3 times that doesnt seem plausible but when I come to selling it, it would be a lot easier with new 100% power battery! So anyone know any cheap sites where I can get one? Thanks List: 1. I didn't think that eBay would be a good option but I found this battery... Can anyone tell me if these specs are reasonable of if there is anything I should look for in a battery? 2. Just out of interest it is £90 on Apples UK site but is there anyway to find out what the specs of an apple supplied battery are?
