    Suddenly deformed itself to death after 3+ years

    • Written by from Yreka

    My battery was still working well until the past week, when it suddenly deformed itself to the no-longer-functional point and has practically come apart. Of course my warranty expired about 3 months ago, so I guess I have no alternative to getting another one.

    The original macbook battery is bad. The battery is deforming after 3 years, it ruined my plastic cover on my macbook and I can't click my mouse.
    I calibrate the battery 3 times a year thinking calibrating may extends my battery life but it does not. I don't have any problem with the maximum charging capacity, it is still 3 hours and 15 mins. It is just deforming and it gets so hot. I may think it will blow up one day.

    My wife's Acer laptop battery is better in quality, I bought her a laptop 3 years ago, the battery still holds the charge and it is not deforming.

    My next battery will not be from Apple, 3rd party battery is far less cheaper and longer warranty.

    Quality product, better than any other computer batteries

    • Written by from Grand Rapids

    When I had a dell, after a year I would have to have my computer on the charger to be able to work. With my macbook, I have had it for three years and my battery life is just starting to be less. When I say less, I mean it lasts at least 3 hours on optimal usage settings still. So all in all, compared to other computer manufacturers I think that this is a great product!

    actually pretty good

    • Written by from Myrtle Beach

    i’ve had my macbook for almost 4 years now. for those of you who know what it means and care, it has 413 cycles on it and it’s going pretty strong. i used to get a full 4 or so hours out of the batter when i first got it. 4 years later? i’m down to an hour and a halfish to two hours depending on what i do. if i stream, then i’m down to about 10 minutes. i didn’t usually follow the thing where you charge it fully and then let it die. when i did, it did help. most likely going to get a replacement battery soon.
    just remember it’s how you treat it that helps it’s longevity. if you go and beat your car up, yeah you’re going to need a new one sooner or later. these things aren’t supposed to last forever.

    It will die, at least mine did.

    • Written by from San Ysidro

    I bought this on April 18th, and it died today, it didn't even last 3 months. We've been using Apple's products for some years now, and it is the first time we have a defective one, I'm hoping that it was an isolated case, anyhow, I'll be heading to the Apple Store tomorrow.

    Best battery I've seen

    • Written by from Oshkosh

    I have used many many Li-Ion batteries. In fact I'm a trained chemist who researches in Li-Ion battery area and have to admit that this is by far the best Li-Ion battery I've seen in any commercial product. I'm still using the original that came with my white macbook (early 2009 model). After testing it professionally, it is at 101% capacity even after 200 cycles and more than 2 yrs later. I easily get more than 5 hrs of output.

    Quickly loses capacity

    • Written by from Vantaa

    I have a 32 month old battery with 272 cycles, and only have 25% of the battery capacity left, translating to about 30 minutes of battery life. The battery has never been exposed to extreme temperatures or handled otherwise carelessly, so these numbers are highly disappointing for a battery with this kind of price tag on it.

    A pretty good battery with an evil side

    • Written by from Orinda

    This battery is pretty good and it has lasted me two years. I however didn't use my computer for a week, and just left it shut off with the battery partially drained. When I next used my computer the battery was DEAD. it had 601 charges on it, and before I was having a 95% battery life. I learned that you need to update the software in the battery chip via battery update 4.1, but the software won't work on Snow Leopard. I did find out how to work around the issue but had I known about this earlier I wouldn't have had to buy a new battery.

    1400 cycles+

    • Written by from Madison

    Maybe I have a low expectation of batteries these days, but I'm giving this battery 5 stars for doing exactly what it promised to and then some. I've had my Macbook for nearly 4 years now. My first battery died after two; I put this laptop through it's paces. It's turned on virtually as long as I am. I keep the screen brightness high and don't use a screensaver or energy saving software.

    The capacity has definitely lessened, but I am at over 1400 cycles after two years of use and can still get a solid 2 hours off my battery while running multiple programs and streaming video. All I've had to do is stick to their suggestion of powering all the way up and not beyond that and then allowing the battery to completely drain. Considering Apple would've told me to replace my battery 800 cycles ago, I can't complain; I'd happily buy a replacement battery now but I can see this one easily lasting another few months or a couple hundred more cycles.

    Lasted 3 years, but falling apart?!

    • Written by from El Cerrito

    This is ridiculous, Apple. I've replaced the charger 6 times, and now the battery is swelling to the point that the plastic cover is being pushed out of the computer?! I have to buy a new one because I can't stand this anymore/it's uneven when placed on tables/it's potentially dangerous, but it's a little ridiculous that I have to pay this much money for a new battery. Just ridiculous.

    Rechargeable Battery- Be aware

    • Written by from TALLAHASSEE

    I had this computer for 2 and half years. Over the years the battery would hold less and less, but never had a problem since I left the laptop unused for 10 days. Even thought the computer was charged and the charger not plugged in, at my return from my vacation the battery would not hold the charge, not even for a second. The charger gives me the green light, but the battery just does not hold. After reading some of the reviews, noticing that a lot of people had the same problems I wish I would have known better. I suggest anybody to read reviews on how to take care of their battery, or that Apple would warn their consumers. I also agree with other people about the high cost of the battery. Overall, in my experience PC laptops last much longer. When my battery died, my mouse pad broke too. That NEVER happened with my PC.

    Life of battery....

    • Written by from Hurricane

    This battery is HORRIBLE!! The one that came with the computer needed replacing in the first 6 months of having the MacBook. This one is less than 2 months old and won't hold a charge even 2 hours. LOVE the computer, the battery, for the price, should be FAR better considering it's an Apple product.

    battery lasts 3 1/2 to 4 hours

    • Written by from newport beach

    the battery has outlasted all my prior laptop batteries. i still have the original battery, 3 years old and 872 cycles later, and it lasts 3 1/2 to 4 hours on a charge. I did upgrade the memory to 4 gigs from 2 gigs. I also upgraded the HD from 250GB to 500GB 7200 rpm and the operating system to snow leopard. i've owned 5 laptops, and this is my first apple, and the first one which i didn't need to purchase a new battery after a year...i'm sticking with apples in the future

    Mac Book Battery

    • Written by from BLAIRSVILLE

    I've had my Mac Book for 4 years and this will be my third battery. I take great care in never leaving it plugged in beyond the actual charging (green) time and to drain it completely before re-charging. When the battery is new, I find that it does last for several hours at first but quickly has less and less charge time before having to re-charge. I have spent a fortune on this computer with new (2) chargers and (3) batteries and had to upgrade to Snow Leopard to even be able to access some of the newer things/software. But, I think that is just the nature of the beast. We can't live without them (not conveniently anyway) and we can't live with the high cost of keeping one around! Otherwise, I like my MAC.

    This battery is way overpriced

    • Written by from Aloha

    The cost of this battery is excessive. I can buy a Kindle for the cost of this battery. If it was actually worth the money being asked for this, I wouldn't be looking for a replacement after 101 cycles.

    Four years of excellece!

    • Written by from mattawan

    I've had my macbook for just shy of four years. I have never taken care to calibrate the battery or make sure I'm charging it and let it die properly. I just plug it in when I feel like it, and take it when I need it. The battery is on its 1139th cycle, thats right one thousand, one hundred and thirty nineth cycle. I obviously don't get the same time out of it as when it was new, but do get a good 3 hours. I upgraded my HD to a 7200rpm which took a chunk out of its life but it still lasts. Running Ubuntu, I get a noticeably shorter charge, ~2 hours, but thats still enough to get me through my classes.
    Over all, this really is a great battery

    Not a complaint

    • Written by from wichita

    I've had my MacBook for 4 1/2 years and still use the original battery. And I use it A LOT! I don't take care to fully charge and then fully run it down or any of that stuff. I've left it on accidentally and it's drained to shut off point a hundred times. It always comes back on. I take it school and it last through all my classes, granted it is depleted by the end of my last class. Macs are great. Having a battery that goes kaput on you after 13 months is not typical. But it can happen. As with any electronic device.
