    Works well if you use it right.

    • Written by from Pensacola

    I am in the Marine Corps and have used my 13" white MacBook (2007) on my most recent deployment to Iraq. Not only has the MacBook itself been able to withstand the brutal elements and environment of a desert combat zone, but without access to reliable power outlets -not to mention the need to use multiple adapters- my battery performed as expected. People who write in negative comments and threaten to go back to PC probably haven't taken the time to read their manual. I have owned two other PC laptops, and they were useless. My wife owns a 1 year old HP 17" laptop and guess what? She wants a MacBook Pro now. The HP gets used by my 5 year old to watch Nick Jr! Learn your Macs, people!

    Bad Reviews?

    • Written by from DETROIT

    This is a good battery, but it is expensive. Everyone that is leaving a bad review keep in mind that keeping your laptop plugged in constantly will kill your battery sooner than expected. This goes for anything running on a battery. You are overcharging the battery. This slowly destroys the battery and it will not have as long of a life span as it should. This goes for almost any electronic device running on a lithium ion battery. They should implement a feature where the power from the outlet is no longer supplied when the battery reaches a full charge. I think nintendo the d.s. lite does this but im not positive.

    never overcharge you battery

    • Written by

    i have had 315 cycles for 17months now and yet, my battery works perfectly 100% health, i think you just need to charge your battery properly, never charge it while its still usable, and most importantly, never leave it charging while u go asleep.

    to person complaining of only 20 minutes use

    • Written by from Columbus

    ALL rechargeable batteries of any sort are meant to be exercised. Leaving the laptop plugged in all the time and never discharging the battery will eventually ruin ANY laptop battery. It's a function of how battery chemistry works. You're supposed to drain the battery fully and recharge it again every now and then- Apple's recommendation is at least once per month. Once a week is a good idea, followed with monthly, or at least quarterly battery calibration cycles (check Apple's support for how to do this.) Don't blame Apple because the battery performs the way all rechargeable batteries perform.

    As a side note: I'm writing because my current battery is finally failing. My MacBook is one of the early ones- it's 2 and a half years old. I can't complain about my battery not lasting long, especially since I rarely used it in the last year.

    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.

    mac book battery

    • Written by from Scarborough

    I have the upgraded black Macbook with the 160 gig hard drive. I've had it for 2 years & the battery is still holding a charge. If you want you batter to work properly you have to run the battery down frequently until the screen shuts off. When you do this the battery can receive a full charge. Once you laptop is charged, use it on the battery, don't leave it plugged in.

    Great but....

    • Written by from Fort Worth

    You have to do complete discharge and charge cycles or the battery wont hold a charge long and the battery dies.

    This is caused because this is a rechargeable lithium polymer battery.

    Rechargeable lithium polymer batteries suffer from the memory effect. This is when gas bubbles grow between the walfers and limits the charge. This can be overcome by doing full cycles but that takes to long.

    You need to know how to use it.

    • Written by from Fort Simpson

    To "What you gonna do about it"

    Let me guess, you leave your book plugged in, sometimes overnight even though its fully charged. That is what is killing your battery. I just learned that and am buying a new battery. It makes complete sense to me. Although it would be nice if something would stop the battery from overcharging, but 'what you gonna do about it"...I'm gonna stop plugging my battery in when I don't need to, easy enough and it saves me on the powerbill.

    Still love my macbook.

    Par for the course...

    • Written by from natchez

    As far as laptop batteries go, this is about par. Rechargeable batteries, by their nature have to be replaced about once a year with regular use. Why? Well, the scientific answer would be that the chemicals inside the battery that are used to hold a charge, are, at first, seperate entities. However, as you charge the battery, drain it, etc. those chemicals that were originally seperate start to mix and bond to one another at the molecular level. The more they bond, the less charge they hold. This is normal. No I don't like it any more than you do, but here's a hint; other than the measures mentioned in previous reviews(brightness, volume, etc.) try unplugging your power chord as soon as you can, unless you are using power. If you are just charging the battery, unplug as soon as you get full charge. Even when your battery is charged, if you are still plugged in, the chemicals in the battery will continue to bond, just as if the battery was still charging.

    Try that.

    Oi, the battery.

    • Written by from carlsbad

    I would just like to say I have had something of a mixed experience with the battery. My wife and I ordered the macbook at the same time, over a year ago now. Her battery recently quit working. Mine works like new. The difference? She left her's on the charger 24 hours a day, whereas I unplug mine as soon as it is fully charged, then i leave it unplugged until the battery is about dead and needs to be charged again. Like one is SUPPOSED TO DO with ANY rechargeable battery. Rechargeable Battery 101: If it's charged, don't leave it on the charger or you'll fry it. Simple. My only real complaints about this battery are thus: 1. It's not idiot proof (and there are a *lot* of idiots in the world), and 2. Yeah, $130 is a tad bit on the expensive side, but I get it. If people have to have it and there's no competition, gouge, gouge, gouge! It's just good business!

    Okay product, but doesn't last unless you take certain steps.

    • Written by from Redding

    I have had my macbook for a while now, and have mixed feelings about the battery. It doesn't last very long, 4 hrs if the screen is bright, and unless I cycle the battery often (let it run down and then recharge) it loses its maximum charge. Some steps I take to prolong its life on a long trip is to a) turn down the screen as low as I can stand, and b) turn off the bluetooth and airport using system preferences. Using this I have gotten my battery to last five hours and forty-fifty minutes. If you plan on going on long trips, you will want this battery.(If you travel by car consider the car charger)

    560 cycles and still at 92% health

    • Written by from Halethorpe

    If you leave the cable in once the green light comes on, you're going to kill the battery. Every month I let the battery completely drain until it shuts off my mac and then fully re-charge it. My mac is 4yrs old, and with 560 cycles I'd say it's done pretty darn well :)

    Four years

    • Written by from Seattle

    I spilled water on my macbook and killed my battery. And it is a shame.

    I've had this macbook for a little over four years with no battery troubles. The battery stays charged for about 3.5 hours, more if I turn on some power-saving settings.

    Hope my next battery lasts at least this long.

    battery life

    • Written by from sarasota

    One of the complaints I see about these batteries is that they only give you 2.5 hours of use. Make sure that under System Preferences > Energy Saver you set the battery state for better battery life. Another thing to keep in mind is screen brightness, wifi, and bluetooth. Turn off Bluetooth and Airport if you aren't using them as they drain power searching for networks and devices.

    2nd time was the charm

    • Written by

    My 2nd battery is on 762 cycles and I bought it 2 years ago. It still says the condition is good. The difference this time is that I charge the battery to 100%, and then immediately disconnect from the power source. While I use it through the day, once it gets down to the warning that it will power down at 5%, then I plug it back in. Seems to work for me! The first time I would leave it plugged in all the time, because a tech guy I worked with said that is was fine to do that. He was obviously wrong. Giving it 4 stars because the battery is still too expensive for my liking.

    Good price at the store

    • Written by from Katy

    If you let Apple replace the battery at the store, it is $99 instead of $129. The warranty is only 90 days, but it is worth the $30 savings.

    Very good, if used properly.

    • Written by from Old Town

    I've had my macbook since June of 2007, the battery has had 892 cycles, and it's still going strong! I've used it properly, with the whole drain it as much as you can then charge it fully. When I do have a full charge, i still get at least 3 hours of battery when browsing the internet and that stuff. I highly recommend this battery to anyone who can use it properly.

    It's all about intent.

    • Written by from Annandale-on-Hudson

    I have had my laptop since May of 2008. I'm a college student, and so I rely on my laptop. While I haven't been the best about running the battery out and then charging it up, my battery has lasted me quite some time. Some would argue that over two years simply isn't a satisfactory amount of time for a battery to run well, that it should run longer, but considering my battery probably still holds a 2-3 hour charge when I'm running multiple applications with the screen at its brightest, I'm not complaining. I've been the type to leave my laptop plugged in while using it, which isn't all that wise with a portable computer.

    According to the Mac "genius" I talked to about getting my 13" black Macbook fixed (the topcase had chipped, which was fixed for free without Applecare), the batteries in my year of Macbook generally run about 300 re-charge cycles, and once it hits that threshold they start to deteriorate, which is why it's important to fully charge your laptop and use it until it almost runs out. Plugging it in before this happens isn't a crime, it's simply better for the battery. I'm fine with the fact that my laptop doesn't hold as much of a charge after two years, in fact it's quite nice. The PC I had before this (it was my mother's, really) had a horrible battery life.

    Though I know I'll likely have to buy a new battery within the next year, I'm quite at ease about it. I know it'll last me another two years, if not more. Considering I could get my topcase fixed for free, I'm not complaining about a $130 battery. It's worth it because my laptop isn't obsolete, it isn't choked with viruses, and it's still functions like I did when I bought it, it just doesn't last as long.

    Early 2006 Macbook

    • Written by from Cuyahoga Falls

    I haven't plugged in my macbook for about 2 months (recently got an ipad 2 and sort of abandoned it). When I finally did tonight, I was told that my battery wasn't charging and that I needed a new one. At first, I was ticked off! 129.00 for a new battery!? But that I started reading the reviews and realized that I was one of the lucky ones! I got my macbook in 2006, and I got 1120 cycles out of it. I hope my new battery works that well because the rest of my computer is fine. That'll do, little battery, that'll do....

    Time For A New Battery

    • Written by from Edgewater Park

    I got my Macbook for Christmas in 2007. The battery burned out about a year ago and now I have to connect it to a power source when I use it. Im finally buying a new one. I believe the reason why my battery burned out is one of two possibilities. One is that I left my computer on sleep for several days or that I left it on the charger for several days. It happened so long ago I can't remember which one it was or it could have been a combination of both.
