    Your battery health fluctuates up and down over time.

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

    Do yourself a favor and stop worrying about that. I did that when I first got my MBP and it drove me crazy. Don't worry about the battery - it will fluctuate.

    Also don't worry about any juvenile responses to this thread. Rather than respond to them, just report them to the moderators via the report post button [​IMG].

    You'll find lots of helpful information in the Forum FAQ/Rules. The links are on the toolbar on every forum page.

    Batteries have a mind of their own it seems. I am currently at 97%; this morning I was 99% and yesterday I was 95%...with that said, I need to recalibrate my own battery but the lithium polymer batteries used in the MBP have minimal 'battery-memory' and tend to have longer service lives than other rechargeable batteries used in laptops.

    Nick, I think the recalibrating that Apple asks you to do does nothing really for your battery physically. It merely calibrates the battery meter to your battery.

    I may have worded it wrong, but I meant the fluctuation of my 'health' level indicated it needs a calibration in order to make the meter more accurate. The advanatges I listed I meant to apply to lithium polymer batteries in general.

    Figured I'd say minimal in the event of a fluke incident. :)

    As I've said many times before, both in threads and in the FAQ that I've encouraged you to read, your battery health will fluctuate up and down over time. Don't worry about it. It's perfectly normal.

    Hi

    Mine went from 84% back up to 93% in the space of about 4 hours yesterday so, no, don`t get too paranoid about battery health.
    Keep it calibrated and follow the advice GGJ linked to, you`ll be fine.
