When should I buy a new battery?

I've had my macbook for 8 months, I'm just wondering when should I buy a new battery?
The cycle count is 310, and checking System Profiler, the battery full charge is 5143.
Should I buy a new battery in a now, or should I not worry about buying a new battery, because I heard 310 cycles was a lot.

The question really isn't how many cycles your battery has, it is how long your full charge is lasting on a calibrated battery. If you've calibrated your battery within the last 60 days and you are getting less than 2 to 2 1/2 hours on a full charge then it is time to get a new battery. If you are getting 3 to 3 1/2 hours you are fine, regardless of your cycles. If you are in between decide if the $125 or so is well spent to get 4 hours or so.

  • When should I buy a new MBP?

    I'm leaving for college in the fall and I would like some help deciding when it makes sense to buy a new computer.  I'm planning on buying a new MBP with Retina display, but I'm not sure if it's totally worth updating yet.  I currently have a Late (October) 2009 White Macbook (2.26Ghz, 8GB RAM, 250GB HD), that works decently, but isn't wonderful--it's slowing down.  I would appreciate some ideas and thoughts on when it makes sense to upgrade:  now, before I leave for college; sometime during the fall semester, after I really know my computing needs (my least preferred option); or, this Christmastime?  If anyone has some advice, it would be much appreciated.
    Cheers!

    Wouldn't it just make sense to put the money for the 7200rpm drive towards one more upgrade on the MBP?  I could just cut that up front cost.
    You can choose to forgo the hard drive upgrade, however 250GB is quite small, meaning your likely using a great portion of the second 50% of the drive, which the read/wrire performance is substancially reduced.
    7,200 RPM doesn't make that much of a battery life dent that one will notice it, but one will notice the speedier response.
    S0 by incrreasing the RPM's and the storage size, plus newer drive with better read/write speeds through technology improvments combined with a zero erase + fresh install of 10.6.1 (your original disks) and Software Updated to 10.6.8 (10.7 is slow) should make a dramatic improvement on that model.
    However a erase + fresh install of 10.6 on that present 250GB can do the job well too, 10.7 is slow and you likely have other problems the 10.6 install will also cure.

    I'm not sure where I can get a copy of 10.6.8.  Do you know where I could obtain that?
    Your computer came with 10.6.1 install disks, hold c or option key down and boot off the disks, use Disk Utility to erase the entire drive (select the drive makers name and size on the left) with Security Option > Zero all data, wait, then when finished quit and install 10.6.1 and Software Update fully to 10.6.8.
    If you no longer have the 10.6.1 disks, call Apple for a machine specific replacement disks for your 2009 Late 13" White MacBook.

    f it turns out that I do need Windows for class applications, do I install it on a partition by using disk utility and partitioning my HD (also, how big does that partition for windows need to be)?
    There are two methods to use Windows on a Mac.
    1: Apple's Bootcamp, which takes the bottom free space on your boot drive (250GB isn't much if you have a lot of OSX data) and allows you to direct install Windows 7 (only) there.
    2: Virtual machine software, which allows one to run Windows (any flavor and Linux's) in a window in OS X.
    You can read about both (pro's and cons) here:

  • Should I buy a new battery from a third party vendor?

    Hello,
    I am totally new to this portion of support and to the world of laptops so please bear with me for a moment. I don't think I need a new battery yet but I did some research on-line and the general consensus seems to be that Apple and batteries don't mix. Should I go with a 3rd party battery? I want to have a spare in case I need it.
    Thank you in advance for your advice.

    If you don't need a spare battery now, there is little reason to get one. LiIon batteries deteriorate a small amount whether you use it or not, so the common wisdom goes. You can buy replacements online overnight if you have no store nearby, so I see little reason to have spares on hand unless absolutely critical. I would have no problem with Apple or Newertech Nupower batteries myself, but even they can go bad at variable times. A 6 month (Apple, I think) or 1 year warranty (Newertech) is about all you can expect. I would question others, especially ones that are too cheap. Counterfeits are very easy to make.

  • When should I buy my new Macbook?

    Im in a bind. I need a new laptop for college and I have a crappy Asus Laptop that is literally a rock. I need advice on if I should wait until WWDC 2014 in June or should I get a new Macbook Pro Retina now. I don't know what to do. My laptop ***** and I am literally close to smashing it. I am a person who wants the latest and greatest but I dont know if its worth waiting or not. Can someone give me some help?

    I have the late 2013 rMBP, and I cant imagine what they can add to this to make it any better.  
    I have the 2.6Ghz with a 1TB Flash Storage.  They use the same flash storage in this as they do in the Mac pro's so it has read and write speeds about 1.2GB/second.  It boots in about 10 seconds. And just everything works FAST.
    My guess is that the next version may have a small speed increase,  But I think you will be extremely happy with the current line.

  • Should I buy a new battery?

    Is it a wise investment to purchase a new battery for my mid-2011 macbook pro, or a waste of money?

    The information in System Information>Power will give you an idea as to the condition of the battery.  Specifically look at this information:
    How much of improved performance will be a function to the degree that your current battery has deteriorated.

    Try:                           
    - iOS: Not responding or does not turn on
    - Also try DFU mode after try recovery mode

    - If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - Try another cable
    - Try on another computer                            
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

    - Try another charging source
    - Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.

  • My MacBook Pro laptop says 'service battery' and doesn't charge very well but my Mac is 5 years old. Is it worth buying a new battery or do you think I should buy a new mac?

    Hi guys,
    I can only leave my MacBook Pro unplugged for an hour maximum and it never seems to fully charge. It says on the Mac to service battery - which I guess means buy a new battery.
    I have had my MacBook for over 5 years now and it does get used probably every day, if not every other. If I brought a new battery would it all work normally again or is it getting old and do I need a new one?
    Also, my charger seems to be playing up a bit now as well. It's seems to be temperamental when I plug it in and takes to while to light up and charge.  I've attached an image of the battery bit on my laptop as the lead seems to be fine - is this normal?
    Thanks in advance guys.

    Is there any application(s) that your current Mac cannot run that only a new can?  Calculate the cost per year of your current MBP and compare that to the cost of a new battery.  Spread the battery cost over a year or two of additional operation, how do the dollar amounts compare?  If the MBP is functioning properly, I generally find it is more cost effective to keep it.
    If the retina display and the SSD storage are very desirable from your perspective, then that becomes a different matter.  You are the one to make the final decision.
    Ciao.

  • Buying A New Battery Again? PLEASE HELP.

    Hi,
    When I first purchased my MBP 15" in 2007, the battery would only last at most a couple hours. It would decrease more and more until it would only last for 10 minutes (I usually leave it plugged in when it is already 100% and overnight).
    I got a new battery a few months ago and it worked great, giving me around 4-5 hours of battery if I remember correctly. I still kept it plugged in at 100% and kept it on overnight. Soon after, the battery would only last 10-15 minutes when unplugged (within a matter of months of buying a new battery).
    Now it doesn't charge the battery to 100%, it stays at 0% so I am required to keep it plugged in. I was wondering whether this was a battery fault or something else. I have no more warranty and was wondering what I should do. I do not want to drop another $120 on a new battery if that isn't the main problem.
    Please help me, I appreciate any kind of information. Thank you!

    Welcome to Apple Discussions!
    Unfortunately you didn't buy AppleCare, or take advantage of the past warranty Exchange/Repair program that existed for batteries for awhile. Sounds like you are out of luck. Have it looked at by one of these technicians, if they charge less than Apple:

  • I have 1 GB RAM on an '07 MacBook Pro. 1) How do I check remaining memory? 2) I have Microsoft office 2004 - do I need to buy more RAM to upgrade to '11? 3) I need a new battery ... Is it worth the $$ to buy a new battery, RAM and Microsoft office 2011?

    I have a MacBook Pro from '07 with 1 GB of memory. The battery is shot and my AppleCare has run out. I just upgraded the OS to 10.6.8. But a few questions:
    1 - How do I even check how much memory I have left on this computer?
    2 - How do I check how many battery cycles are left?
    3 - I want to upgrade to Microsoft Office '11 because I don't have Adobe Acrobat to creat pdf's and I need to be able to do this for school... Instead of buying acrobat, I figured I would just upgrade to Office '11 because I can generate pdf's from Word. Roughly how much RAM does Office '11 take up?
    4 - Does Apple still make batteries for this computer (from '07)? How much do they cost?
    5 - How much does 1 more GB of memory cost?
    AND lastly -- is it even worth it to spend the $ on more RAM, a new battery and Office '11?
    Or does it make more sense to just get a new computer entirely? (trying to avoid this).
    ANY help would be sooo appreciated! Thanks.

    1 - How do I even check how much memory I have left on this computer?
    If you're asking how to check to see if you need more RAM, open Activity Monitor and go to the System Memory tab, then compare page outs and page ins.  If page outs is 10% or more of page ins, you probably need more RAM.
    2 - How do I check how many battery cycles are left?
    There's no limit on the number of battery cycles, it's just that the more cycles you've used the more "worn out" your battery gets.  You've got a 4-year-old machine, and if it's still got the original battery, it's probably about time for a replacement battery.  You can check battery health using System Profiler...  look at the Power section under Hardware.
    3 - I want to upgrade to Microsoft Office '11 because I don't have Adobe Acrobat to creat pdf's and I need to be able to do this for school... Instead of buying acrobat, I figured I would just upgrade to Office '11
    You don't need Office 2011 to create PDFs.  Any application capable of printing can create PDFs on a Mac.  Just choose File -> Print, but instead of clicking the Print button in the print dialog, click the PDF button and choose Save As PDF in the menu that appears.
    4 - Does Apple still make batteries for this computer (from '07)? How much do they cost?
    5 - How much does 1 more GB of memory cost?
    I'll "ditto" sig's answers to these.
    AND lastly -- is it even worth it to spend the $ on more RAM, a new battery and Office '11?
    Or does it make more sense to just get a new computer entirely? (trying to avoid this).
    If Office 2004 is still working fine for you, stick with that and don't incur the costs of Office 2011.  As to the RAM, only add more if the test I mentioned above indicates that you need it.  If you buy more RAM when you don't really need it, you won't see much (if any) performance improvement.  That just leaves the battery...  and if the machine is still doing what you need it to do and you don't really need a new machine for anything, you could definitely buy a new battery and get a few more years out of it.

  • When should i buy a iMac?

    I have been wating for a while to buy a iMac. Some sources say it will come out sept. 12, others say october, or even early 2013. i really need one now but should i buy now though? i mean what happens when i buy one now but then the new one comes out in october?

    Don't buy anything from Best Buy.
    But what about the new model being so close, i just dont want to regret the buy.
    No one knows about any new models. Significant upgrade cycles for Macs has historically been on the order of every year or so. There is no guarantee that will continue though.
    "so close" is not significant for a computer that will serve you well for several years.
    If you decide to buy from Apple they have a 14 day, no questions asked return policy. Should you buy a new Mac and another one comes out during that short period, you can return it for a full refund and buy the latest.
    There's nothing wrong with using your existing computer. Replace it when it no longer does what you need it to do. If that happens to be now, you have your answer.
