    Two years ago I bought my sister an iBook off ebay. Old G3 iBook, 800MHz and it had the original battery, which after 5 years, understandably didn't hold much of a charge. If she was lucky she'd get 10 minutes out of it before she needed to rush to a power socket.

    I have no idea how, as far as I know it defies the laws of… well, of lithium ion batteries, but today her same battery now lasts upwards of 2 hours, and it's growing in longevity every week. And sometimes… once it displays 0% in the battery icon, it lasts for another 2 hours!! Is this normal? How has this happened?

    She uses her laptop every single day surfing the internet, but I'm very surprised she's managed to somehow coax the battery into lasting 2000% longer. I thought this sort of thing was unheard of.

    Maybe it met a girl battery and fell in love and made new batteries?

    Really though, if a battery is charged and used properly it calibrates itself. The problem is most people don't calibrate their batteries, especially older ones.
