Hi, folks. My G3 iBook is 2.5 years old, and one of the factors in my decision of when to replace it is whether I'm likely to have to replace the battery in the immediate future. I very rarely operate the machine on battery power. In fact, I would probably only ever run it off battery power when I'm on holiday and using WiFi hotspots, which would be a couple of hours every three months or so. With that in mind, you'd think that it would take ages to wear the battery out, but I've heard that Lithium Ion batteries deteriorate over time regardless of how much they are used. I've decided to try running my machine on battery power for a couple of hours tonight to see if it's still okay and, to my surprise, the charge seems to be holding pretty well. Does this mean that I can realistically expect acceptable performance from my battery for another 3 - 6 months, or is it likely to suddenly kick the bucket in the near future? Any experiences or specialised knowledge that anyone could share would be appreciated.
