    Cycle your Battery

    • Written by from los angeles

    If you follow the instuctions in the manual, and cycle your battery once a week. You can get about 4 to 5 hrs of battery life out of your mac book pro. i tried cycleing the battery and it really works and restores the batteries life. But the key is you have to do it once a week.

    Battery gets very, very hot, in my opinion, but great battery life so far

    • Written by

    I think the battery life is pretty good on the MacBook Pro. I was on a three-hour flight the other day and my Mac battery died right before landing. Other PC users around me had to shut down because of battery issues 45 minutes before. After the flight, I actually had one business person ask me what kind of computer I have and questions about the battery b/c he couldn't believe it lasted so long.
    However, in my opinion, this battery gets extremely hot and more so than any PC that I have worked on or the PowerBook I had until I upgraded to this one. So, be sure to wear pants or use a pillow if you're going to use your laptop in your lap!
    The design is great for the MacBook Pro and so is the battery, I just wish they would've used a larger fan in the MacBook so it would keep this thing cool. I think it's more a flaw of the computer design and less of the battery, though.

    Cycling works well.. Try it!!

    • Written by from Jaffrey

    I use istat pro to monitor battery health. My battery was down to 52% health and holding a noticeably limited charge. I never bothered with full cycling.

    After cycling the battery several times over the last week, I'm back up to 86% health and the longevity is once again very good. According to istat pro my battery has 308 charges on it, and it is still going strong.

    I've never experienced the hot battery some are talking about. Is this the battery or the computer getting hot? Under prolonged heavy loads (use Activity Monitor to view processor load in your dock) the cpu does get hot and the fans will come up to speed. istat pro can show you the speed if you want.

    How can I cycle?

    Fully charge and discharge your battery, no software required. This is easy, just charge it until it is fully charged (the light on the power cord turns green), then unplug it and use it on battery power until it automatically turns off. Do this several time.

    You will be happy with the results.

    Not impressive

    • Written by from Portland

    My MacBook Pro developed the sudden shutdown issue after about 14 months. I cycled the battery frequently and generally took good care. It's life was never the advertised 5 hours, not even close. Swapping out the battery with a friend's solved the sudden shutdown issue, so clearly the battery is the problem. Given the very large numbers of people who have had this issue (google: sudden shutdown macbook) on several different Macs, I'm really disappointed Apple hasn't done anything. I'll never to switch to Windows, but I feel shabbily treated by Apple.

    Great for a few months...

    • Written by from WYLIE

    I bought my MacBook Pro Feb. 08' and the battery will no longer hold a charge for more than an hour, even though all I am doing is using Pages... Now I am replacing my battery because one hour of typing is unacceptable. I think Apple should seriously start addressing this issue..e.g. make longer lasting batteries for older model macs instead of just making "longer lasting" batteries for the newer models.. Quite frankly I am fed up with my computers battery life. I absolutely hate that my computer just shuts off without warning! I have lost many hours of my work due to the short battery life.

    After only owning my macbrook pro for a 18 months this battery is a now a desktop weight. It charges to 100% then causes the computer to just randomly shut down at 60% power. Apple refuses to fix this product or stand by it by recalling these treacherous batteries. If you want a real battery that will last you go to fastmac's website. And no this is not some add from this company. I am just a small time person telling the truth.

    Absolutely worthless. Not becoming of Mac at all.

    • Written by from Hephzibah

    I had my macbook pro for about a year and the computer just starts dying at 80% power. No "low battery" warnings no flashing lights or alarms, it just turns off immediately without even saying it's shutting down. And to top it all off, tech support tells me it's my fault and I have to buy another one. I checked the terms and conditions for the protection plan and it said it doesn't cover batteries unless there's a flaw in the craftsmanship. This about as flawed as it gets. They need to do a recall on these things. This is a disgrace and we're being taken advantage of.

    Miserable Battery! Make it right, Apple!

    • Written by from Philadelphia

    I wouldn't bother adding my voice to the choir if I weren't so upset, like everyone else here, at my MacBook Pro battery's sudden death syndrome. Barely a year old, my battery lasts 5-10 minutes after being plugged in for days. Apple makes great products--we probably all agree or we wouldn't be singing our complaints--but this is criminally bad: for the environment (I'll have to throw away or "recycle" my worthless battery), for the consumer (we waste valuable time and money thinking about and correcting these problems), and for Apple's soul.

    Bad battery life

    • Written by from Traer

    I am on my second MBP battery after my first one gave out after 3 months. I have had this one 9 months. I have had 96 recharging cycles, and Apple says it should be good for 350. It only holds battery power for about 20 minutes, even after a full charge. Now I have to spend another $129 on a new battery--which better last longer! C'mon, Apple! Get your batteries to work!

    This is the third battery I have had to buy for my MacBook Pro. The second one lasted one year and now only keeps a charge for about a half hour. This is ridiculous. Love the MacBook Pro but the battery stinks. I tell everyone that "Yes, Macs are more expensive because they are better!" Can't say that about their batteries.

    I would give it 0 stars if I could!

    • Written by from Denver

    This is the worst battery I've ever had. I've had my laptop for 3 years now and had to replace the battery 2-3 times/year that I've owned it. I love my computer, now if Apple could just get a decent battery to go along with it!

    Why do Mac batteries have to stink!

    • Written by from San Francisco

    I am about to buy the third battery for my less-than-two-year-old 15" MacBook Pro. This is unacceptable. Plus, all three previous laptops that I have owned have been subject to battery recalls. I have owned Macs all my life and owned one of the first 1000 production models of the original Mac. Steve, you should stop licking your screens and start worrying about your hardware a bit more. Why did I have to put up with a G3 Titanium that gave me lap-burn? Why do the letters on the keyboards come off within a few months? And - most of all - why do your batteries stink They wouldn´t let me say s--k) Very liberal Apple!

    I've had my macbook pro for over a year now. The battery used to last for about 4 hours. Now, for no apparent reason, the battery is at 20% health and I get MAYBE 45 minutes out of it on the lowest brightness, airport turned off, etc.. Of course I'm not covered by AppleCare anymore either. Apple needs to recall these batteries, because it simply isn't fair to its customers.

    Instant Death

    • Written by from Oceanside

    Had current laptop battery for 1 year. I use the application MiniBatteryLogger to keep track of battery events and health. One day I have a Max Capacity of 5357 mAh (97% of original capacity of 5500 mAh). Two days later I have a max Capacity of 762 mAh (13%) and my laptop won't stay on for more than 20 minutes. These batteries blow. Having to calibrate the battery once a month or maitaining a charge between 40-60% is weak. The end user shouldn't have to just through all these hoops to get reasonable battery life. And then charging $129 for a replacement battery is a straight jack move!!

    This Battery is Garbage

    • Written by from Middletown

    I hate this battery. It worked fine for a while but now is garbage. Under 300 cycles and it will just shut of at like 40% charge. Also it only runs for about 1 hour now and then is dead. I tried cycling and everything. Also I took it to Apple tech and they told me it was my fault. They then proceeded to tell me how to care for a rechargeable battery and surprise i had done everything they suggested. When i told them that they were dumbfounded. Just frustrates me that it is garbage.

    Terrible. Awful performance.

    • Written by from Edmonton

    I've had this battery for a little over a year, and it's malfunctioning already.

    My Macbook Pro shuts down instantly after about an hour's use, I lose my unsaved work and have to restart. When the battery was new, OS X would give me a warning that the computer was running on reserve power and going to sleep. Now, it shuts down entirely, even though there is 0:40 left on the battery indicator.

    Do a little online research, you'll find this is a common problem among these batteries. Why hasn't Apple announced a recall?

    Ridiculously Bad Battery Life !!!

    • Written by from Houston

    In 2.5 years of owning my MacBook Pro15", I am about to buy my 4th, yes, FOURTH, battery! Steve Jobs: This is totally not acceptable!

    On each of my batteries, I have cycled it between 50 to 120 times, but it makes no difference. The last one is only 10 months old and it is now only holding 50 min of charge. I am happy that this battery is not catching on fire like the few in the past decade, but this lousy life is shameful to have come out of Apple.

    I don't care if you censor this posting, as long as you kick your entire power management group in their behind for this huge failing.

    Batteries Are Tricky.

    • Written by from Giggitymm

    Originally I was amazed at how expensive these things were from Apple, So I went the cheap route via Offbrand Amazon battery. Only to find out the battery would not charge, without the laptop being tilted, and one day I come home to the battery expanding and leaking. Amazon gave me a refund, But then I still didnt have a battery! So I bit the bullet and went to the apple store and picked up this battery. Works perfectly, after about a wekk I was getting 4-5hrs of life in my 2007 MBP. 4 Months later and no noticeable degration. Mine worked out fine, but there are lots of lemons. At least when you buy it at the store, you can just bring it back and get it replaced. NEVER BUY OFFBRAND!

    I've read most of the reviews for this product and I'm glad/sad to see that I am not alone. This battery is TERRIBLE. I barely had my macbook for a year and my battery dies at 80%. This is unacceptable.
