Are 4 hour batteries still in production for the macbook pro?

My 2 hour battery is starting to only charge to 1 hr 45 and sometimes less. It's like I have to keep it constantly hooked to the power chord. Are 4 hour batteries still in production?

Apple is still producing batteries for your MBP, yes. The "higher capacity" (though certainly not double!) batteries from FastMac are also still available.

  • HT4110 What is the best battery setting for the MacBook Pro 13 Retina display?

    I want to know the best setting for the battery for the MacBook Pro 13 Retina display.

    To add just a little
    Keep it plugged in when near a socket so you keep the charging cycles down on your LiPo (lithium polymer) cells / battery, but not plugged in all the time. When not being used for several hours, turn it off.
    And best "tip" is if its near a socket,...plug it in as long as you can (especially at home) since cycle count on the battery are the "miles that wear out the tires (battery)", however again, not plugged in all or most of the time.
    http://www.apple.com/batteries/notebooks.html
    "Apple does not recommend leaving your portable plugged in all the time."
    General rule to remember of Lithium batteries is:
    Never drain them LOW  & dont always/often store them HIGH
    While cycle count is commonly seen to be the “miles” on your Lithium Ion pack cell in your Macbook, which they are, this distinction is not a fine line at all, and it is a big misconception to “count charge cycles”
    *A person who has, for example, 300 charge cycles on their battery and is recharging at say 50-60% remaining of a 100% charge has better battery usage and care than another person who has 300 charge cycles at say 15% remaining on a 100% charge. 
    DoD (depth of discharge) is far more important on the wear and tear on your Macbook battery than any mere charge cycle count.  *There is no set “mile” or wear from a charge cycle in general OR in specific.    As such, contrary to popular conception, counting cycles is not conclusive whatsoever, rather the amount of deep DoD on an averaged scale of its use and charging conditions.
                              (as a very rough analogy would be 20,000 hard miles put on a car vs. 80,000 good miles being something similar)
    *Contrary to some myths out there, there is protection circuitry in your Macbook and therefore you cannot overcharge it when plugged in and already fully charged
    *However if you don’t plan on using it for a few hours, turn it OFF (plugged in or otherwise) ..*You don’t want your Macbook both always plugged in AND in sleep mode       (When portable devices are charging and in the on or sleep position, the current that is drawn through the device is called the parasitic load and will alter the dynamics of charge cycle. Battery manufacturers advise against parasitic loading because it induces mini-cycles.)
    Keeping batteries connected to a charger ensures that periodic "top-ups" do very minor but continuous damage to individual cells, hence Apples recommendation above:   “Apple does not recommend leaving your portable plugged in all the time”, …this is because “Li-ion degrades fastest at high state-of-charge”.
                        This is also the same reason new Apple notebooks are packaged with 50% charges and not 100%.
    LiPo (lithium polymer, same as in your Macbook) batteries do not need conditioning. However...
    A lot of battery experts call the use of Lithium cells the "80% Rule" ...meaning use 80% of the charge or so, then recharge them for longer overall life.
    Never let your Macbook go into shutdown and safe mode from loss of power, you can corrupt files that way, and the batteries do not like it.
    The only quantified abuse seen to Lithium cells are instances when often the cells are repeatedly drained very low…. key word being "often"
    Contrary to what some might say, Lithium batteries have an "ideal" break in period. First ten cycles or so, don't discharge down past 40% of the battery's capacity. Same way you don’t take a new car out and speed and rev the engine hard first 100 or so miles.
    Proper treatment is still important. Just because LiPo batteries don’t need conditioning in general, does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesn’t need conditioning.
    From Apple on batteries:

    Storing your MacBook
    If you are going to store your MacBook away for an extended period of time, keep it in a cool location (room temperature roughly 22° C or about 72° F). Make certain you have at least a 50% charge on the internal battery of your Macbook if you plan on storing it away for a few months; recharge your battery to 50% or so every six months roughly if being stored away. If you live in a humid environment, keep your Macbook stored in its zippered case to prevent infiltration of humidity on the internals of your Macbook which could lead to corrosion.
    Considerations:
    Your battery is subject to chemical aging even if not in use. A Lithium battery is aging as soon as its made, regardless.
    In a perfect (although impractical) situation, your lithium battery is best idealized swinging back and forth between 20 and 85% SOC (state of charge) roughly.
    Further still how you discharge the battery is far more important than how it is either charged or stored short term, and more important long term that cycle counts.
    Ultimately counting charge cycles is of little importance.  Abuse in discharging (foremost), charging, and storing the battery and how it affects battery chemistry is important and not the ‘odometer’ reading, or cycle counts on the battery. 
    Everything boils down to battery chemistry long term, and not an arbitrary number, or cycle count.
    Keep your macbook plugged in when near a socket since in the near end of long-term life, this is beneficial to the battery.
    Peace

  • Where is the User Guide for the MacBook Pro 13-Inch 2012?

    Hi there,
    Trawling the Apple Support Manual pages (http://support.apple.com/manuals), I couldn't seem to find the correct User Guide.. even searching with my Serial Number.
    I am looking for the MacBook Pro 13-inch (2012 10.8.2 Mountain Lion) User's Guide.
    Searching with my Serial Number, the results are:
    MacBook Pro (13-inch, Mid 2012) - Quick Start Guide
    MacBook Pro (13-inch, Mid 2012) - Important Product Information Guide
    Searchng manually, all i can find are:
    MacBook Pro (13-inch, Mid 2010) - User Guide
    MacBook (13-inch) - User Guide... which is the OS X v10.4 Tiger version
    Is there not a "MacBook Pro (13-inch, Mid 2012) - User Guide" ????
    Thanks,
    Chris

    I have already worked out that there's no full User's Guide.
    Why would a new mac User, like myself, want a Quick Start Guide (which came in the box), and then not want access to an actual full User Guide.
    I have been using the other PDF's for general guidance, but I shouldn't have to make do with other guides.
    Apple.... Is it too much to ask that my £1250 purchase comes with the proper documentation ?!

  • Please update the specs for the MacBook Pro - 8GB RAM Max

    Hello,
    Someone needs to upgrade the specifications for the MacBook Pro now that 4GB laptop SoDIMMs are shipping and compatible with the MacBook Pro.
    See my blogpost on the subject at http://blogs.technet.com/keithcombs/archive/2008/07/05/testing-my-apple-macbook- pro-with-8gb-of-ram.aspx.
    Thanks,

    Hello again,
    Regarding having them update the specs, one can dream. Dreams are free. LOL. Hopefully the memory makers will update their specs as more makers start supporting a large memory configuration.
    The 4GB sticks I am using are http://shop.kingston.com/partsinfo.asp?ktcpartno=KTL-TP667/4G
    I did not do an extended test of the sticks in my MBP. Their home is in the ThinkPad I have because it is running Windows Server 2008 with Hyper-V.
    As you can see from the link above, these little suckers are pricey. But consider the price of 2GB SoDIMMs were $950 when they entered the market a couple of years ago. The price will drop.
    I asked the Kingston rep that sent these to me if online sites like newegg.com would have them soon. She indicated no, but the corporate buying sites like CDW and Zone would. So check around. They just started shipped a couple of weeks ago so be patient.
    If you have any other questions, please stop by http://blogs.technet.com/keithcombs/archive/2008/07/05/testing-my-apple-macbook- pro-with-8gb-of-ram.aspx and ask there. I'll see them much more quickly.

  • Is it bad for the MacBook Pro to play World of Warcraft?

    Is it bad for the MacBook Pro to play World of Warcraft?

    There will just be a little more wear and tear than "normal" use, because the heat goes way up and the fans max out while playing, as with most gaming. I guess that affects the overall lifespan of the laptop.
    I played all the time on my MBP early 2008, and still play on my 2011 MBP. The '08's fans had to be replaced but still works fine.

  • How will an external Hard drive designed for the macbook Pro work with my White Macbook?  My  white macbook has a Firewire 400 and the G-Tech HD has a 800 to 400 compatible cable for the firewire.

    I am asking this because I want the G-Tech Hard drive  says that it is designed for the macbook pro.  Yet, I want to back up faster with by using my firewire 400 which is not an option on the one designed for the white macbook that does not have a firewire (only a USB port.)  The G-Tech Hard drive comes with the 800 to 400 compatible cable and has 5400 RPM with 750 GB.  Also, I've heard that laptops with low battery (mine all the time)  won't have the power for a bus powered Hard drive (as in no ac plug in adaptor.)  Can I just plug in my laptop?  Any one know the answers from experience with this hard drive?

    As far as I know, if a harddrive works with a Macpro, it should work with the Macbook: if your Macbook is low on power, plug in the AC adapter
    If your Macbook has a firewire port, then it should be fine. BUt i would do somemore research first.

  • Does anyone know the difference between the Applecare Warranty for the Macbook Pro and the Applecare Protection Plan Auto Enroll 607-8192-B APP FOR MacBook

    Does anyone know the difference between the Applecare Warranty for the Macbook Pro and the Applecare Protection Plan Auto Enroll 607-8192-B APP FOR MacBook

    AFAIK, the difference is that the auto-enroll occurs automatically when you purchase the device and you will have to disburse the cost right there and then. Whereas the other comes in a box, can be purchased separately later and you must manually enroll your device into the system to activate the additional protection. This must occur before the base one year warranty is over.
    So, if you don't want to pay up at the moment you buy the computer, you can wait up to say 11 months and buy the AppleCare warranty extension later. Just be sure to complete the enrollment BEFORE the base warranty is over, else Apple will not honor the extension (all in the fine print). This applies to all devices that offer an AppleCare option: notebooks, desktops, iStuff, etc.

  • Has Apple pulled the SMC update for the Macbook Pro Retina from the App Store

    Does anyone know if Apple pulled the SMC update for the Macbook Pro Retina? I can no longer see it as an update in the app store. I am refering to the update that enables power nap on the Macbook Pro Retina.

    It showed up in my ML App Store.
    What is your SMC version?
    Mine is
    SMC Version (system):          2.3f28

  • Multiple internal hard drives for the MacBook Pro. Is it possible?

    Hello and greetings I am planning on purchasing my first MacBook Pro for school and travel soon. The internal storage of 256 GB SSD is not enough for me and I don't want to upgrade through the Apple website when I initially purchase my MacBook Pro. I was wondering if it's possible to install a second or possibly even third internal hard drive even if it's pretty thin.
    I was looking at http://www.newegg.com/Product/Product.aspx?nm_mc=AFC-TechBargains&cm_mmc=AFC-Tec hBargains-_-NA-_-NA-_-NA&Item=N82E16822152291
    And
    http://www.newegg.com/Product/Product.aspx?Item=N82E16822178125
    Could someone tell me if I could install these drives alongside the already installed SSD I don't want both of these hard drives installed at once. I was wondering if either one would fit inside, id rather have the Samsung one as it is has a larger capacity. So would the Samsung one fit or should I go along with the Seagate. That's even if I can install a second internal hard drive.
    Will either of these drives be able to sit alongside my SSD? This laptop will be carried around with me all day for school and work and I can't afford to be using an external hard drive. I don't want to spend a lot of money on purchasing another SSD for my computer just a normal HDD is fine for me.
    Thanks In advance.
    Joseph, 15

    Depending upon which MacBook Pro you purchase, you may be able to put a second internal drive in it.  If the system comes with an internal optical drive, you can purchase a drive trave for your second HDD to replace the optical drive and ha ve a second drive internal in the MacBook Pro.  Be aware that some people have had issues with doing this when they have tried to put a very fast (SATA 6.0Gbps drive) into the optical bay, but not all users have this issue.I know of no way to put any additional drives inside your MBP other than that though.
    As long as you are purchasing a new MBP, the bare Seagate drive you linked above should work fine, I was not able to follow your first link to say anything about it.

  • Is there siri for the macbook pro

    Is there siri for the macbook pro

    We are not allowed to speculate on future Apple products or services.
    I don't want to be talking to my Mac anyway, and not only that, having a copy of everything said stored on Apple's servers.
    It's enough as it is that our smartphones are spying devices, not to also include our computers.

  • Do I need trend smart surfing for mac for the macbook pro

    do I need trent smart surfing for mac for my macbook pro?

    That's totally up to you. If you have the need to restrict the web sites that can be visited, then a product such as Trend may be worth the cost. If you are only worried about malware from your own surfing, then I consider the price for Trend excessive and unnecessary. The freeware ClamXav and a bit of common sense - about what you download and from where, not falling for scams and fakes that ask you to provide personal information, and in keeping your operating system up to date -  should be sufficient.
