    Great Product! A must have.

    • Written by from Sydney

    this is a great product if you use it properly. Because it is a lithium polymer battery it needs to be charged fully then drain fully and charged fully etc... to keep it healthy. I get about 4 - 4.5 hours out of this if I i drain it and then charge it (like above). when i first used it like normal i only got about two hours until i realized that you had to do this. This is a great product and if you use it in this way you can even achieve as much as five hours! This is a great product and i would highly recommend it.

    note: if you use this technique from the start, the battery heath can increase from what it was when you first get it.

    Like you even have a choice

    • Written by from Dedham

    I love seeing 5-star reviews for this thing. Here is the truth: the MacBook battery is big, heavy, and will only get you an additional 2-2.5 hours of battery life under normal usage. Yeah, you need one. No, it is not great.

    I got this battery because I was going to be going on a 10 hour plane ride. It was very, very nice to be able to keep my computer for almost the whole trip. I have read a lot of people saying that it last for 3 or 4 hours, but here is a tip, turn down the brightness level on the screen to as low as it can go (I can get by on a notch of 1 when there is a light on in the room). When on the lowest level, the battery lasts for around 5 hours, sometimes a little less, sometimes a little more. I would recommend this for someone who uses their MacBook for long periods of time.

    Should last longer....much longer

    • Written by from Waterford

    My wife and I both have MacBooks. Her Battery just died after 16 months of use. I've read that in order to keep them up they need to be fully drained and fully charged each and every time. Sorry, but that's not 'real life'. You buy a notebook to be portable, not to stay plugged into a wall all day. (I have a desktop for that)

    My work computer is standard issue Dell laptop and I abuse the heck out it with no battery problems after 4 years (on planes, in meetings etc.).

    I expected more from Apple. 16 months is unacceptable performance in my mind.

    13 Month Problem

    • Written by

    at 13 months the battery died completely. this is not a case of the battery holding less of a charge. one day i picked it up and it said there is no battery installed. this is extremely frustrating.

    judging by the other reviews, this is a very common problem. for apple to continue to produce and sell such faulty products, i must start to question the companies integrity.

    Like another reviewer said, DO NOT LEAVE YOU LAPTOP IN SLEEP WHILE UNPLUGGED FOR OVER A DAY OR SO. In sleep mode it'll drain the batt far past it's reserve level and into the point of no return. I accidentally did it when I thought I shut my computer down, and now the batt shows 0% all the time, or a little slash through the battery icon. Sad face. Now I need a new battery. The lamest part of this is if you accidentally disconnect the power supply (trip over it or move the computer) the whole thing shuts off. (it's an obvious statement, but a super frustrating one.)

    I've had my Macbook for about a year & a half, and I've taken care to calibrate the battery like you're supposed to. However, for the past 3-4 months, I can't take my laptop anywhere without the power supply, because the battery lasts for (if I'm lucky) 20 minutes. My warranty is up, so now I have to spend $130 on a new battery. Two of my friends have had this same problem, as well.
    I'm usually a huge fan of Apple products, but this is ridiculous.

    Ok until it dies

    • Written by from Gainesville

    Mine was fine until about one month after the year's warranty when it suddenly went dead without warning. In my opinion, this is defective! I never had this problem with my previous lap top. Before that its performance was fine but long performance was not my main requirement, portability was. My son bought a new black MacBook and his battery died in less than 6 months. What is Apple doing to fix this problem? It is fine to replace the battery free of charge the first year but what about someone like me whose battery fails at 13 months or someone whose battery fails for the second time at 14 months. Are you listening, Apple? You are usually very good at responding to user complaints.

    I got my Macbook 13'' in november 2006, about 5 months later the battery stopped working completely. It is now recognized on the toolbar as a giant x and no matter what i try it still won't charge. I've checked the mac help/troubleshooting but nothing works. Now I'm stuck with a all the time plugged-in laptop, (sort of defeats the purpose of a laptop) and always end up moving too fast and the cable comes out and the computer shuts down. I also cannot believe the price of a new battery! I love mac but if I'm going to be spending 129$ every 4-5 months to replace the battery might as well get a Dell !

    Batter dead after 5 months

    • Written by from Brick

    13" MacBook battery dead after 5 months. OK this is crazy. And its not covered under the 3 yr AppleCare I purchased. Even after following Apples instructions to let the battery drain fully and recharge fully. Again this is crazy who does this in the real world. I am very dissapointed in Apple. I now have to pay $130 for a new battery, which might not last again. Come on Apple get on it. This is a big problem. Fix it.

    Replacement again

    • Written by from St-Charles-Borromee

    It's been six years since I bought my Macbook 1.1, good laptop except for the battery. Today I have to buy my 3rd battery replacement. Four batteries in six years is not a good ratio at all.

    Apple always comes up short n batteries

    • Written by from Palm springs

    Ive been a loyal Apple enthusiast since 1984. Owned the first Mac when it was only available to universities. Their form factors and designs are sexy brilliant and interfaces are intuitive.

    Power, however, has always come up short, Whether it be the ipod, the iphone, and now the MacBook. I ve had mine for just about two years and the battery flat out failed -- and Im a very casual user, who often times takes the battery out to spare battery life while using AC power.

    My brother's family has 3 macs -- all 3 batteries failed just after the first year.

    Not sure why Im writing a review. Its not like you have a choice in power sources. Perhaps Apple is reading these posts and will realize they kep having practices that alienate their loyal customer base.

    great computer - short battery life

    • Written by

    I love my Apple MacBook but I am quite disappointed that after only ten months my battery has died. The battery indicator shows that it is fully charged; however, I can no longer run the computer on battery power. Very weird. Hopefully the Apple Store will be able to help solve this issue.

    Total garbage!

    • Written by from Hickory Creek

    After about 11 months of use, my battery will not work anymore. I payed $1399 for a Macbook, and my battery won't even function.I sent it in through AppleCare, and their exact words were,
    "Our analysis has determined that although your battery no longer has the capacity to function at a level necessary for the optimum operation of your unit, it is not defective."
    de·fec·tive: imperfect in form or function : faulty

    Keep it plugged in it will die

    • Written by from new york

    I'm about to be on my third battery now in three years. It's incomprehensible that apple could have overlooked such a simple circuitry solution as bypassing the battery from ac power once it has fully charged or furnishing an option in the power profile to "cycle" the battery if the user should choose to leave it plugged in all the time. In any event all Mac buyers should be alerted to the fact that if you leave your computer plugged in at all times the battery will be gone in one year or less, especially those purchasing replacement batteries. Very bad business Apple Computer. I thought you were better than that.

    Battery bulge after 71 cycles

    • Written by from Healdsburg

    The idea that the "bulging" battery issue is for depleted batteries etc is BS... my current battery has decided to literally split its seams after 71 cycles. The fact that apple doesn't replace these is definitely an extremely sore point with this customer.

    I had no idea what was wrong with my macbook and the mouse pad button. I did some research...It was suggested that the problem was caused by a bulging battery. I took off the shell cover I had on the computer and sure enough, bulging battery!

    2nd Battery Swollen

    • Written by from Indore

    I have a macbook, my factory battery got swollen 6 months out of warranty period. I bought a new one and today even that has swollen. Definitely an issue with either the batteries or the laptop itself. I have other Apple laptops in the family, none have had this issue.

    I don't know what the fuss is all about

    • Written by

    People here are upset that their $130 battery doesn't work. It's not the battery that doesn't work, its the user. ALL Apple batteries inside ALL of their products require great care. Apple's Li-Ion batteries need to be charged to full cycle, and then drained all the way down to ≤ 5%. Only then do you get excellent performance. I've had my MacBook since August 24, 2007 and as of February 18, 2012, not only is the computer still doing pretty well for it's age, but is holding at an excellent 74% battery health after 1264 charge cycles. Apple says this battery is only supposed to last ~300 cycles under normal usage. You need to understand to use this battery ABNORMALLY. You need to buy it and charge it for a full 24 hours the first time you install it, drain it to 0%, charge it to 100% again, and then use it. Only charge the battery when the message appears. Don't listen to the other morons on this review page that complain about Apple's battery not working. Apple's products always work.

    Genius Bar says bulging battery normal sign of wear

    • Written by from Greenville

    I have an early 2009 MacBook. When I took the alarmingly bulging battery into the Genius Bar I was told this was normal and that the bulging is a "safety feature" to prevent explosion. I was then sold a $130 replacement. How is this not a defect?
