    Hi

    I'm running istat pro in my dashboard.

    There is a section for checking your battery status.
    Percentage charged.
    Cycles.
    Status.
    etc.

    There is one that says Battery Health: 87%

    What is this referring to?

    battery health refers to the your battery's current capacity compared to its original i believe.
    hope it helps

    Holy Crap!
    :eek:

    My battery is only a couple of months old.
    I've only done 27 recharges.

    Will it help if I calibrate the battery?

    I think calibrating will help, have you never done so earlier?

    At one point mine was saying 95%, but now it's back to 99% and I calibrate every 3-4 weeks or so.

    I calibrated it when I got it - and have run it down completely a couple of times since.

    Like I said, its a only a few months old.
    (my old battery fell into the recall category and had it swapped out - so I guess I got it in Sept or Oct)

    and also battery health greatly varies... sometimes one day it will be like 89% and after new recharge 94%
    but as a general rule of thumb, calibrating every month or so is good ;)

    i personally have a 7 months old mac and 65 cycles and its still holding 94% of its charge so im content with that

    Mines at 100%! But my old MB was 85% when I got it, and the MB before that was 94%. I just got a really good one.
