    When is the last time you calibrated your battery, to make sure your readings are accurate? This should answer most, if not all, of your battery questions:

    I normal use all the power in my battery, till it goes to sleep, then i recharge it, probably about once or twice a week. So its most likely the correct information...

    That's not calibrating. Read the CALIBRATION section of the Battery FAQ for steps on how to calibrate your battery properly.

    The advice above is appropriate, accurate, and the best possible approach.

    Why the post received a down vote is beyond comprehension.

    The voting system may have been implemented with good intentions, but I truly believe there are too many negative immature people that hang out here. It's these individuals that make the system completely irrelevant.

    UPDATE! just hit 2000 cycles. Haven't cycled it lately, so the health is a little bit low, but its normally around 88-92%

    How long does it actually last on a full charge?

    Apple says otherwise;

    RedRider that is a remarkable amount of cycles. Would you mind telling us your charging/ use habits.

    Read the link you just posted, which is included in the Battery FAQ I posted. The OP has an Early 2009 MacBook, which does need calibrating.

    Wow in 414 days you added more than 500 cycles, that's truly a lot.

    He has a unibody computer and he doesn't say where he lives. ie. If he lived in the Southern Hemisphere he'd have spring later in the year.

    Anyway there is no way he'd get 2000 cycles with a removable battery.

    As the Apple article states, only MacBooks from Late 2009 and later come pre-calibrated and don't require regular calibration. If the OP has had their MacBook since early 2009, it can't be a Late 2009 model. Unless the OP has misstated which model they own, the OP's MacBook does require regular calibration, according to Apple.

    He didn't say he had early 2009. He said he'd had it since spring in 2009, which in the lower hemisphere would be later 2009.

    You're really grasping at straws.

    ...and it's conjecture on your part too considering you don't know the model of the unibody MacBook.

    Anyway, draining lithium batteries is bad for them, so doing it unnecessarily is not good battery management.

    The pre-calibration doesn't apply to all unibody models, but only those Late 2009 and later, which excludes the Late 2008 and Early 2009 unibody models.. If you read the context of this thread, you'd know that calibration is necessary and recommended in this case, as the accuracy of the battery readings is in question, and the OP's MacBook is not a model that came pre-calibrated. Rather than try to make the situation fit your post, it's more helpful to recommend something that's appropriate to the situation.

    So, tell us, which model do you have since members here don't know.

    I use it, a lot.


    PS: After one full discharge and charge, battery health is now at 89%.

    That's a Late 2008 model, introduced in Oct. 2008. According to Apple, the battery does require regular calibration to give accurate readings. You never indicated if you ever calibrated the battery, using the instructions posted earlier in this thread. Did you?
