    Hey guys,

    New to macrumors forum. I was looking into buying a new macbook pro and I was just looking at my current macbook 13 inch and I hadn't checked my battery health for a while so I went and had a look. I was extremely suprised to see my battery had done 1046 cycles and according to istat, my battery was at 92% health...

    I have had my macbook 13 inch since november 2007. It has been having a few problems lately with over heating but I was wondering if it was normal to have a battery that had gone through so many cycles and still have around 4-5 hours battery life (when I am just browsing the net and doing uni work i.e not watching movies or listening to music)

    Guess I am lucky :)

    If you haven't calibrated your battery properly, the readings are likely inaccurate. If you're getting that much life after that many cycles, you should be glad. Is that 4-5 hours until it shuts down, or 4-5 hours estimated, as displayed by iStat Pro, iStat Menus or coconutBattery?

    This should answer most, if not all, of your battery questions: Apple Notebook Battery FAQ

    I haven't re-calibrated my battery at all. However, it does last 4-5 hours still, if I use it for only word processing and web browsing.
