    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.

    extremely poor life

    • Written by from Cochrane

    My macbook now says that I have to change the battery and it won't charge. Checking the system profiler, I've had 63 cycles. That's $2 a charge. So now I'm forced to purchase a new batter for $129.

    It is very sensitive

    • Written by from Ottawa

    If you let it discharge and do not use it for a week or two it may never charge -- read the forums.

    poor charging capabilities over time.

    • Written by from Chestermere

    I bought my macbook last year in Aug after always using PCs. Love my macbook and would never go back however I find it absurd that my battery is dead after 13 months. And when i say dead, i mean it will not hold a charge at all!

    Yet another battery

    • Written by from Fort Wainwright

    My macbook goes through about 1 battery per year. This is HORRIBLE! I wish apple would recall the batteries or the computer, which ever is the source of the problem. I am a loyal apple customer, but I have had to replace my battery on this one macbook at least 5 times. EEEKK! Thats a major expense on an already expensive computer.

    All I can say is that this battery is unreliable.
    Some people are happy with it. They get over 400 Cycles
    after 18 month and it still lasts for 2-3 hours.
    For other people, the battery is dead after a few month only.

    I am not among the lucky ones.
    Again, for me this battery is unreliable - pure lottery.
    Try your luck!

    I personally expect more from Apple! For lottery I use 6/49.

    a shame

    • Written by from Libertyville

    much like the cases of other reviews ive read, my battery is starting to die as im approaching the 1 year mark. its really a shame that this looks to be taking away some of apple's customers. i hate to see such a great computer and OS be looked down upon by people because of the battery. for their own sake, they should try to figure out this battery situation.

    Before I start this review, let me say that I love my MacBook, it's been great and runs pretty good.

    I've had it for about two years, right before I started college. Last week my light on my charger wasn't fully orange and was flickering. I find it isn't charging. I setup an appointment with Apple and go to talk to them today. After waiting 30 minutes after 4:20 for an appointment that was for 4:20 I get to the guy. He does a few things, presses some buttons and now it is suddenly charging again. However he says I need a new battery.

    Not sure how he got it to charge again but apparently the lithium batteries only last about two years. It's 130 bucks to replace it via apple. I didn't think these batteries went out like that, I thought I was going to be good for at least 4-5 years.

    In short, be careful, because these batteries have a terrible life. And it says I've used 190 cycles...which from what i'm reading is pretty minimal, that's just messed up.

    dead battery

    • Written by from Bluffton

    I obviously got this battery with my macbook, 15 months ago. I really hadn't even noticed my battery life draining, but all of a sudden one day the battery just died!!! I have no idea why. Its still brand new and not over used and only works when plugged in. I tried a friends battery and it works so that is definitely the problem. I am no where near a store, and I've got to spend nearly $150 to get another battery, I hope this isn't an every year problem. If so Ill be switching back to PC. Love my Mac to death, but I am not made of money.

    Sneak Attack...of FAILURE

    • Written by from Westerville

    I am just beginning my junior year of college and purchased my 13" macbook just before my freshman year so I have owned this computer a little less than two years. I follow the instructions concerning fully charging/depleting the battery and just last week my battery held a full 2.5-3 hour charge. Now, after letting my battery run itself out last night it is in a complete state of uselessness.

    The alert next to my battery says "(Not Charging)" "Replace Battery Now" and I can run off of nothing but wall power. As a student I cannot take my laptop to classes or use it in a professional setting without a charger (for which there is not always an outlet).

    This warning is not so much for the battery as the Macbook itself. Because while I don't like what has happened, we cannot help purchasing another of these batteries because that is what's compatible with our laptops.

    However, any purchasing an already expensive Macbook be cautioned! You will have to replace the battery...SOON! Great while it lasts...which isn't very 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.

    Quickly goes the way of the Dodo

    • Written by from Toronto

    This battery is great for the first few months and then starts dying like it's going out of style. I'm at the end of the life of my current one, and battery power only lasts me about an hour max before my computer fully shuts down. Overly expensive and totally not worth it-- I might as well just run off A/C power forever.

    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!)

    third battery in two years.. is that normal?

    • Written by from Portland

    So i just got my THIRD battery for my macbook in just under two years. The first one Apple replaced for free because it only lasted four months. That last one has been hanging on for the last few months barely holding a charge so i finally had to break down and buy another one.

    $130!!! For how long these things last they should be half that price.
    I love my macbook but hate this battery issue...So depressing.

    macbook battery

    • Written by

    I have had my macbook for a little over a year now.. and the battery is completly dead. I cannot run the computer without it being plugged in. I followed the proper instructions to callibrate the batter in the beginning and i always kept it with a full charge. There was no indication that the battery was even going. I went to turn it on one day after using it the previous night and it wouldnt turn on, i figured that the battery was just low so i plugged it in to charge it and there was just an x through the battery indicator? Other then the battery going I love my computer, it is great for what i use it for (music and internet) and i wouldnt go for a different one... i would just like a battery that lasts

    Poor battery life- demand a new one free!

    • Written by

    After 12 months of owning my MacBook the battery went dead- one of the corners was yellowing and looked defective. Demanded a new battery at my local Apple Store and the Genius Bar rep gave it to me! 2 stars for giving me a free one, but really poor battery design that should be fixed. ALL MacBook owners should be re-issued new batteries at no expense.

    I have had 3 batteries in three years. They love to spontaneously fail and become worthless. I love my MacBook, but loathe the battery. Apple is pretty unresponsive when you try to contact them about it too. They love to blame you and tell you that it is because you can't have it plugged in all the time.

    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.
