    Hey guys, so basically, my 11 mo old mid 2008 white macbook's battery has only had 190 cycles, but it's already down to 70% battery life. It won't really hold much more than 2:30 of battery life. Apple has said that a healthy battery should hold at least 80% of battery health at 300 cycles. I follow their tips about making sure the battery isn't just sitting there, and to not just leave it there charged. Is this a problem? If I go to apple (I still have my warranty), could they check it out and replace it? I'm a student, so I really don't want to go and pay another $130+ to get a battery from them, and my warranty is almost over. Thnx :apple:

    They most probably will replace it for free, as as you said, they guarantee 300 cycles with 80% battery health.

    If they don't replace it, you can save a lot of money buying a replacement battery through eBay. There are online battery stores too, but generally the cheapest solution for batteries I have found is eBay.

    Good! That's what I thought, and I guess I'll drop by the Apple Store sometime this weekend. Thanks!

    Alright, if they won't replace it, when time comes I might turn to it. I saw they had some for around 70 bucks, but the bidding gets annoying sometimes :D Thank you.

    Does any one know if I have Windows 7 boot camped, will it void my warranty? Should I remove the partition before going to apple? Thanks.

    What you do software wise is not voiding the warranty.

    And Boot Camp is a feature offered by Apple, so why should it void warranty.

    But make a backup of your HDD in case they wanna keep the MB, which is highly unlikely in the first place.

    Ok, was just wondering because Windows 7 isn't officially supported yet for Boot Camp.

    There are plenty of new batteries for your Macbook on eBay starting at $45 if shipped from Hong Kong/China or $55 from the US. These prices are after shipping, using Buy It Now, new from a reputable seller.. So you don't need to bother bidding.

    A lot of times people spaz out when bidding and send products beyond Buy It Now prices.:eek:

    I'll remember to take a look at that too. I'm kind of paranoid now because I once bought a 4GB mp4 player from Hong Kong, and things seemed great, until it started going freaky and turns out it's only has a 1GB capacity. Seller's review = great, but couldn't get in contact with him.

    Not wanting to add fuel to the fire, but I'm wondering if the OP left his mb plugged in all the time, or if he used it regularly.

    That to me seems pretty good! How is yours like that? Mine has 165 fewer cycles on it than yours, and is 17% less healthy than yours.:(

    I use it regularly for school (so about 180 days), and i basically use a cycle per day. until recently, i've realized that i shouldn't just leave it in because a friend of mine told me, so i've been doing what they had on the apple website, to just charge it, and leave it in a cool dry place. i've done monthly calibrations and stuff, but i don't understand why it's this bad right now.:confused:

    So I went into the Apple Store today. It was extremely busy, but the Genius took a look at macbook, and loaded the diagnostics software off the iPod nano he had with him there. The battery life was hanging around 80%, and he said it was pretty typical of a MacBook that's 1 year old. But he replaced it anyways. Thanks apple.

    thats awsome to hear :):) i hope the same thing happens for me haha

    hi sorry to hi-jack, seemed a waste to start a new thread over it..

    my MBPs battery is at 74% after 232 cycles. its the third battery ive had and there is no warranty left on the laptop. will they still replace it?

    i also have my "backup" battery that reads 254 cycles and 79%, any chance of that being replaced?

    it seems that i am pretty hard on my batteries ;)

    well i rang apple, and apparently my batteries are out of warranty.. (true, one is two years and one is 1.5years), but i was under the impression that this battery "scheme" ignored that, does anybody have any information on this?

    from my last post about my battery... I just checked coconut battery, and it seems to me that the numbers are a little higher.

    does this mean I re-calibrated it or something??

    No, all it means is that for at least this cycle, your battery is holding more than the optimum charge. For example, my CoconutBattery results compared to my friend Maxine's;

    Mine (Black MacBook 2008 4,1) - battery kept active, drained and charged regularly
    Current charge 4809 mAh
    Maximum charge 5065 mAh
    98% charge remaining
    Current capacity 5065 mAh
    Original capacity 5020 mAh
    100% battery health
    Load-cycles 219
    Age of Mac 14 months

    Maxine's (White MacBook 2008 4,1) - battery is usually connected to AC power
    Current charge 4680 mAh
    Maximum charge 4680 mAh
    100% charge remaining
    Current capacity 4680 mAh
    Original capacity 5020 mAh
    94% battery health
    Load-cycles 178
    Age of Mac 11 months

    This kind of difference between capacities is mainly due to how you use your battery. Max keeps hers plugged in and that is causing the capacity to diminish though stagnation (imagine a pond silting up), and mine is used everywhere and I try to take good care of the battery, so mine is riding just above the original capacity.

    Not wishing to boast, but a couple of Genius bar staff have commented on this. Bought my MB in October 2006.

    [​IMG]

    I use it almost daily (except when it's in having the cracked palm rest replaced for the nth time :rolleyes:), and try to always fully charge and discharge the battery. Currently the battery lasts me about 3h of averagish use (i.e. web/email, office apps).

    My MacBook is 46 months old and the battery health is pretty poor at only 69% health with 378 cycles. This MacBook is used so my guess is the previous owner kept it plugged it in alot which has caused the diminished capacity. Getting about 2 hours with basic internet browsing and iTunes use; going to purchase a new one soon.
