    HORRIBLE battery Less than 1 star!

    • Written by from tucson

    This battery is a rip-off. First of all, the battery life is deceptively advertised as long-lasting, you're lucky to get 45 minutes if you have 1 application open. RIp-off and overpriced!

    I bought my MAC last October and pretty much 51 weeks later my battery is dying quickly. The warranty only cover 1 year, now I probably have to shell out $130 every year to keep my laptop running. Big disappointment. I would think Apple could of come up with a better battery instead of making people pay this ridiculous price each year. Wish I could use the new 7 hr battery on my Mac. But then again, how true is that advertising. Probably will not buy another Mac laptop till they either resolve this issue or at least extend the warranty of their batteries.

    batt. died but brought back to life

    • Written by from Saint Michael

    After 14 months of ownership, the batt. started to only lasting a few minutes. This is what i did 1. On batt. power turn the computer on and let it run until it goes completely dead. 2. Take out the batt. and let it sit for at least 5 hour's. I let mine sit for about 12 hour's 3. Put the Batt. in and charge it completely, While charging do not turn on the computer just let it charge. This worked for me, I hope it work's for you. Good luck

    Love Apple, Love my MBP, HATE their batteries

    • Written by from Hannibal

    Seriously, Apple makes the best computers on the planet yet the WORST batteries. Not sure how they do it, rather, don't. Long ago I had a ThinkPad by IBM, it got 8 hours battery life in 1999, in 2001 it got... 8 hours. Every MBP and my first iBook 12" in a year battery life was halved and performance hit (i.e. couldn't do as much) and within a year or two I was out $130ish every time for a new battery.

    Welcome to 2010, my one year old MBP's battery at only 271 cycles is at only 49% health and can't hold a charge for more than an hour and a half... what the hey? It started at four hours and slide pretty quickly into the twos. You mean to tell me a friend's clunky four year old Dull Chumputor laptop is still clogging away at 80% of it's original battery life with a very hard pressed life and my MBP is 50% in a year?


    Apple, FIX YOUR BATTERY LIFE PROBLEMS! Read these reviews, we're not fools, make your batteries more dependable or cheaper to at least take a blow off the fact people need to get new ones every year, heck, whatever your markup is, maybe that's why you have so much cash-on-hand as a company... from the battery sales.

    Battery Bulging After 35 Charges

    • Written by from Brooklyn

    I purchased my Macbook and found out that I really do not take it anywhere and it mainly sits after my desk. After 18 months I only went through 35 battery cycles. I am very upset to see that my battery is expanding in size and pushing the lid away from the computer.

    Slim but prone to swelling

    • Written by from Mountain View

    Obviously, the battery fits nicely in the body of the new MBPs. However, I've had mine for a couple years and a while ago the bottom plate covering the battery started to bulge out. It was annoying, but since I use my MBP more like a desktop I didn't care very much. I assumed the cover had somehow become warped.

    Eventually, I found out that it was actually the battery which was pushing on the cover. It had become swollen and eventually put so much pressure on the mouse pad that the computer thought it was in a constant state of 'click'. Pretty lame problem, pretty expensive fix.

    Poor Battery Performance

    • Written by from BEVERLY HILLS

    Couldn't agree more with the other posters here who say that, after a year or less, the factory battery is running at 2 hours or so. A great disappointment.

    Horrible Battery = class action suit?

    • Written by from Anytown

    I've seen a lot of reviews about this battery that sound like the experience I had so I'll add my $0.02. I've had my MBP for 16 months (16-18 seems to be the range of life for this battery.) The worst part about it is, all of my local Apple stores don't carry this model (or they're all sold out because I'm not the only one???) If I had known this battery would last me 16 months, I would be using something else. This sounds like a flaw in design or manufacturing that Apple should make right. We'll see if they do something about it, but I'm not holding my breath.

    I have had this laptop for about a year and a half and I am already replacing the battery. I can find the previous model of Macbook Pro batteries in abundance at every Apple Store I have been to, yet this battery is sold out everywhere and it is on a 2 to 3 week backorder. I think that speaks volumes to the dependability of this product. The battery in my old Macbook Pro lasted 3 years. The poor quality of the new Macbook Pro batteries is simply unacceptable. It is doubly unacceptable given how difficult it is to even get your hands on one. Now I am stuck using the power cable for the next 3 weeks until I can get a new battery; not really helpful when you are using the laptop for business. Great job Apple!

    Help for bad batteries

    • Written by from burlington

    My battery has gone through EXACTLY 4081 full load cycles, and it is 132 months old. It is running at 5% capacity, with 329mAh out of 5500 mAh.

    Im not sure what Apple receomends to maximize your battery, but the ones that dont know about the battery technology:

    Batteries for sot advanced laptops are Lithium-ion, which is fairly new in this feild because of their instability issues. Ofcourse this is fixed with stronger casings and proper charging protocols.

    Anyhow, this battery type is extremely sensitive to how you charge it. For the iphone (same battery type), Apple suggests keeping it plugged in as much as possible. This is because, once a Li-Ion battery dies 100%, it stays dead. And when it dies near 100% it is very bad for the battery. The reason I mention this is because its much different than the more well known lead acid batteries, which are not only longer lasting, but last longer if you completely discharge them, and recharge them.

    Bulging Battery

    • Written by from Arlington

    Late 2008 15in MBP
    Original battery now bulging 3.5 years later, but track-pad still functional, base is not flush
    407 cycles, 94% health, 94% charge
    Getting roughly 3 hours on battery with active browser but no streams

    Rarely turned off and usually in sleep mode when not in use. Mostly plugged into outlet.

    With proper care, this battery is very durable

    • Written by from Coral Springs

    These batteries must be calibrated at least once a month. The battery should be run all the way down until the computer shuts itself off. Then leave it off for at least 2 hours and ideally no more than 5 hours. Next, charge it all the way up. You can use it while it is charging.

    I have done this routine faithfully for the past three years. I have recharged mine 341 times and still have 92% of my original capacity.

    Don't expect much.

    • Written by from North Muskegon

    I've had my MacBook Pro for a little over two years and the battery needs to be replaced already. I'm lucky to get two hours of use; I average at 90 minutes or so of just casual web browsing. Forget it if you try to edit pictures or run Photoshop. I've learned that if I have 50% battery charge left, then I have about 50 minutes of use remaining. You'd think it would charge as fast as it dies, but nope. It can take hours to fully charge if you're using the computer while its plugged in. Just ridiculous.

    An AWFUL battery. I'd say "do not buy", but really, there isn't much of a choice.

    Giving problems just after 1 year and 2 months

    • Written by from Somerset

    Very Disappointed!
    Now I understand why the warranty on the battery is one year.
    It started giving problems about 1 year and 2 months after I bought my Mac Book Pro.
    When it reached 1 year and 6 months I noticed the icon, "Service Battery".
    I took it to the store, they ran the Apple Diagnostic toolkit and it showed that it is a battery defect.

    Then the good news. Even thou it is a defect I have to buy a new one since the warranty is just one year, but the new battery has a 2 year warranty.

    I wonder why the new one has 2 years and the one that came with the laptop had just 1 year.

    You take your conclusions.

    It works

    • Written by from Houghton

    The product itself needs 5 stars because it's the exact battery you need for MBP Late 2008 and, so far, it's working fine.
    I am taking out a star since I am not happy with the fact that the same battery (that came when I bought my MBP) became swollen. Be aware of that.

    Poorly engineered then ignored

    • Written by from whitewater

    My wife's 5 year old plastic MacBook battery is still going strong, but my top of the line MacBook pro's is dead in a little over two years, taking out trackpad and bending aluminum while it did so.

    As an early adopter and strong Apple advocate I have felt left out in the cold on this issue. Even acknowledging that it is a problem would mitigate the undertone of "your crazy, that is what they are supposed to do." It is a manufacturing defect. It sounds like Apple has fixed the problem with newer MacBook Pro models without the removable battery, but a lent hand to the early adopters who helped launch the unibody line would be appreciated.

    I understand that batteries are a consumable piece of a laptop, but when a battery dies its swelling should not stress and disable other components in the system.

    Not bad

    • Written by from Grand Forks

    I have had this same battery on my 15in MBP since mid 2009. I have had no problems with it, but lets face it having a battery for over 3 years is pretty good. One thing people need to realize is that you are not supposed to drain you battery ever. New batteries do not have the "memory" that old batteries have had. The trick to long battery life is keep it above 20ish percent and do not leave it plugged into a power source, unless you absolutely need to. If you treat it right this is a good product, I will be buying a new one!

    High Technology, Low Performance

    • Written by from Hollister

    I bought a new 15" MBP in 2009 with an extended warranty. The first battery lasted less than two years, and swelled sufficiently to prevent the trackpad from operating properly or allowing the battery cover to fit flush. I got a replacement battery free and, when the trackpad failed to operate properly, that was replaced also. A year later, the second battery failed - bloated as a dead pig - and, the trackpad didn't work, and the battery cover wouldn't fit. When I tried to purchase a second battery from the "premium reseller" (my warranty had expired 2 months earlier, the "new" battery serial number indicated that it was almost 3 years old. My laptop is now a desktop.
