    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.

    Great

    • Written by from Asotin

    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.

    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.

    4 yrs later and I'm finally replacing the battery

    • Written by from Bend

    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!

    Heads Up

    • Written by from Daleville

    I saw that many of you wrote a review on how you're "not surprised" about the failure in your battery life. Remember, your notebook is a PORTABLE, it is NOT a laptop. These computers are made to be portable with the adapting charger. If you let the life in your battery run out, then your battery will indeed not charge to it's fullest, nor will you get the maximum amount of life from the battery power source. You can check to see how many times you've ran your battery down by going to "about this mac" on the apple icon located in the top left corner of your screen. Click "more info" and scroll to where you see "power" on the left. Also, download the free software "battery update" if you see that your computer isn't communicating to the battery like it should be. You can tell if you're updated on your battery by click HD/system/library/system config/batteryupdater/apple+i (info). If you're a macbook you need battery updater 1.2. If you're an os x, you'll need 1.3

    Apparently People Don't Know How to Use a Lithium Ion Battery.

    • Written by from Denver

    Just like most cellphone batteries, this is a lithium ion battery, something that — if you've ever taken chemistry you would know — is one of the most powerful chemical combinations for a battery.

    However, like all batteries it has a power input capacity that when over filled will either melt the battery, or cause it to die over time. That is the same case with this one, so in order to maintain its life and keep it healthy, you have to use all that power you've been flowing into it.

    So if your battery is becoming useless very quickly, it's because you aren't using it for a battery, you're using it as a liaison between charger and laptop, so buy a desktop if you want something stationary.

    Laptops were designed to be mobile. So use them that way.

    Great Battery

    • Written by from San Diego

    If you just cycle it properly you are fine. I have 138 cycles on mine and it is still at 100% battery health and lasts for hours (4ish depending on what im doing). I am very happy with this battery. If you keep your computer plugged in all the time the battery is going to die fast. All i do is charge it overnight, and then run it til its dead. I never plug it back into the wall if it has over 20 min of battery life left. Just cycle it... high to low... if you do this, it will last you a long time. I couldnt be happier

    537 Cycles with 98% Health!!!

    • Written by from Marianna

    I have been reading all of the negative comments on the macbook battery, but mine has performed very well. I have only had my macbook for 19 months, but my cycles count is 537 because I never turn my computer off. After having a full charge, I never plug it back in once I disconnect the power cord until the battery is almost dead. Often I even run it down to the point that the screen shuts off. I always let the computer fully charge before I unplug it if possible. If I do have to unplug before a full charge, I let it run all the way down again before I plug it back in.

    Battery Information:

    Battery Installed: Yes
    First low level warning: No
    Full Charge Capacity (mAh): 4940
    Remaining Capacity (mAh): 4924
    Amperage (mA): -1385
    Voltage (mV): 12313
    Cycle Count: 537

    Hardware Overview:

    Model Name: MacBook

    Apple guarantees cycles NOT years of use

    • Written by from Albany

    IF you bought your laptop battery from Apple, it is guaranteed for a certain number of cycles NOT for a certain length of time. If your battery has problems, take it to the Genius bar and have it checked out. If you have a real Apple battery and it has fewer than the rated number of charging cycles then they will give you a new one for free. (Does NOT matter if your AppleCare has expired.)

    I have an old MacBook Pro and an old MacBook (both bought in 2007). Have replaced the Pro battery twice. The MacBook still has the original battery with 2168 cycles. iStat Pro says "Health: 87%", but I am going to replace the battery because it has begun dying too quickly at low charge.

    I keep the electrons flowing in laptop batteries by using the laptop without the power supply and then plugging it in when not in use. I never leave the power cord connected when fully charged.

    The battery life is not great. I got about 4 hours in the first year of using my MacBook and have gotten about 2.5 hours since then.

    The Pro battery is not good, but if you get it to a Genius at first sign of a problem, you might get a free one. The MacBook (non-Pro) battery is great if you treat it right.

    Lots of Misinformation

    • Written by from Dallas

    I have owned my Macbook for over two years now, and the diagnostic on the battery still rests at 95% health. With a little bit of knowledge and attention, these can provide cycle after cycle of full recharge and long operating times.
    I have read a lot of reviews defaming the longevity of these batteries and booing Apple for not giving consumers another choice. I have also read misleading articles about how to best cycle or condition your batteries, and let me just say there is a lot of bad advice and misinformation out there.
    The solution to the majority of lithium ion battery problems, however, simply comes down to a few easy steps. First, it's ok to use the laptop while plugged in to a power source the majority of the time - I should know, I do - as long as you follow the charging and discharging suggestions. When you put the laptop on the power supply, try to make sure you let the battery come to a full charge. It's ok if you don't get to 100% every time, getting it there once every couple of days or so will solve many problems. Likewise, allow your battery to fully discharge every now and then. If you've never seen the "reserve power" warning, your not doing yourself any favors. Again, it's not necessary every time, but once a week at least will ensure the maximum capacity of you lithium ion cells. (26 months - 432 Cycles... and counting!)

    Great Battery!

    • Written by from LITTLE ROCK

    I use my macbook as my primary work computer. I purchased by macbook 18 months ago. I'm still using the original battery. Each day I use the laptop until the battery is almost completely drained (less than 8 minutes left). On average I recharge the battery 2-3 times a day. I have over 872 cycles on the battery (which is extreme). It still holds a charge for more than 4 hours. This will change if I'm watching a dvd or listening to a cd. But, this is far far better than any of the Dell batteries which I exhausted in less than a year.

    Macbook Battery

    • Written by from amawalk

    I don't understand why everyone hates these batteries. I have the first generation macbook and have owned it since Sept 2006, dropped it from my top bunk dorm room bed countless times, and STILL on the original battery. My battery needs replacement now because after almost 3 years, I am at 50% capacity. Charge it fully, (till the green light comes on) unplug it so you don't overcharge it, and run the battery till the computer shuts off. I have over 520 cycles on my battery. Thats pretty good for a battery thats almost 3 years old. Also the new macbook pro is rated at 1000 life cycles so having my battery now last more than half that life is more than what i can ask for. Use it right and it will last you.

    My battery lasted almost 5 years, then started swelling/bulging and losing charge too fast, needing to be replaced. Not bad for a laptop battery! Just keep an eye out for the swelling before it causes damage.

    works, and splendidly

    • Written by from brooklyn

    This battery really is a relief when travelling a long distance and the mac is my mobile entertainment center. the macbooks battery life is NOT quite as long as the specs would have you believe, although im sure that figure varies greatly on the nature of usage. there is no shortcoming i can see from this accessory, not at all. however, i am curious about one thing: i get the impression that apple deliberately made this batter compatible ONLY with the white macbook despite the fact that the architecture and software on the black model are identical. what gives? is this some sort of facist method of preserving color coordination? good product though...lets hope battery segregation doesnt prove to be detrimental to those needing it for the more popular black model, and thank heavens my WHITE ipod is indiscriminate as of late :)

    956 Cycles and counting

    • Written by from Orem

    For those of you that don't know how to use a battery I have received 956 cycles on this battery over a three year period. First of all, to get the most out of your battery you need to charge the battery then unplug it. After the battery goes down to 10 % remaining then you plug it in. Second of all don't just keep it plugged in to the charger, it is a battery. Great battery if used correctly.

    Excellent Battery

    • Written by from Edmonton

    Compared to other computers, Apple's made a good battery. Some people are reporting 1-2 hours, however you need to learn how to optimize. Keep your display brightness to a minimum and turn off your AirPort when not in use while on battery power. Close unused programs running in the background, and keep it plugged in when you don't need battery power. That will keep it running 4-6 hours easily!

    Impressive battery

    • Written by from Washington

    After 1,667 battery cycles (and 5 1/2 years), my 13in. MacBook battery is finally dead. It took me through 3 years of law school, an entire keyboard (which had to be replaced because all the keys rubbed off), the Bar Exam, wedding planning, and 3 different jobs. A hard-working battery, if you ask me! Until just a few days ago, I could get about 3 to 4 hours out of one charge. Not too shabby. I only wish the mag-safe chargers lasted as long (I've had about 8 of those)!

    Impressive durability

    • Written by from East Lansing

    I go to MSU and always take my macbook around campus with me. I've had the macbook for 2 years now and the original battery still gets me an hour and a half with WiFi being on. Not too shabby considering how much I "abuse" the battery by leaving it to charge over night and using the computer while plugged into the wall. Also, $130 for a battery is cheap. My dad just had to replace his 3 month old Sony battery, which was $450!

    3+ years . . .

    • Written by from Downers Grove

    After 3 years, I still get right around 3 hours on a full charge, sometimes more sometimes less depending on what I'm doing. My current cycle count is 1182. After going through some of these reviews, it looks like that is pretty solid performance for a laptop battery. As far as how I've maintained my battery/charging habits, I have no idea. Never really stuck to any sort of regiment, though I ALMOST NEVER turn my computer off or reboot it, noticed someone else mentioned something similar so maybe thats the trick?
