    Amazing Battery!

    • Written by from Bloomington

    I bought my Aluminum Macbook (late 2008 model) in early 2009, so I am going on six years with this computer and this battery is still performing nearly like it did when I first got it. Even though I have nearly 1000 cycles, it's still going strong. Proper maintenance with computer will ensure a long life, they tell you to do it for a reason!

    Service Battery

    • Written by from New York

    After 3 years of using, my laptop's battery is going down of it capacity. It's always shut my computer down automatically even it's full charged.

    I checked the Power information: Cycle count is 213 and Condition is Check battery.

    Awesome!

    • Written by from South Jordan

    I'm on cycle number 1564 right now! It still holds a charge for a few hours while surfing the web. It came with my computer when I bought it the day that the aluminum style macbook came out back in '08. I don't know how long batteries are supposed to last, but this one is still treatin' me right.

    Got lucky

    • Written by from Alexandria

    I'm at 94% after 449 cycles. I kinda wish it was one of the 8-hour batteries, but no complaints for its stellar performance as the type of battery it is.

    Draining the battery

    • Written by from Toronto

    My ex is an electrical engineer and his advice, for all rechargeable batteries to extend the life of the battery, you should let the battery get to less than 5% before charging again. Once it's at 100% it should be unplugged. This somehow extends the battery life. I have tried it and it works. Hope it helps.

    No problems here...

    • Written by from Accord

    Cycle count: 735
    Condition: Normal
    Health: 93%

    This battery lasts about 3.5 hours under normal use (internet browsing, e-mail, etc.) and just long enough to watch most movies in HD. People that are complaining about their batteries dying prematurely need to learn how to take care of them.

    Great battery

    • Written by from San Diego

    I got my Macbook for Christmas in 2008. It is now July 2013 and I have yet to change its battery. I just got the "Replace Soon" message two months ago, so this battery has lasted me almost five years! It still holds its charge for about 2 hours unplugged.

    Full charge capacity (mAh): 2751
    Cycle count: 1505
    Condition: Replace Soon
    Amperage (mA): 2039
    Voltage (mV): 11600

    Replaced first after five years, back to 4hr life

    • Written by from Bethesda

    After 654 charge cycles and five years of use, the old battery was down to 60% of capacity and failing. Bit the (rather expensive) bullet and am glad I did. With an SSD, 8GB of RAM, and this new battery the old Unibody MB is still going strong. (New replacement battery has a capacity of 4525mAh, which is better than the design capacity of 4300mAh.) Now I can wait for a Haswell rMBP or rMBA!

    Look after your batteries!

    • Written by from El Medano

    I have had mine 15 months and it still charges 100% and gives me a full day´s work as I don´t take my charger with me. I ALWAYS run it flat before charging as recommended. It charges to 100% and no change in the time I have had it. Lots of "short" charges WILL ruin the battery.

    I've had my Macbook for 22 months now. My battery is at 275 cycles and the battery capacity is at 4006 mAh. The original capacity was 4100 mAh. Maybe there are defective batteries out there, but mine has been just fine.

    500 plus cycles and you are complaining??

    • Written by from Phoenix

    it's rated for 300, anymore is a bonus, I love all the people throwing up stats over 300 cycles and complaining. You'll get more use if u drain and recharge weekly, rather than rarely draining as u most do but it's only rated for 300 cycles and anymore is gravy now go buy a new battery

    Great Product

    • Written by from Williamsport

    I bought my Mac in March 2009, it's a late 2008 13" unibody. I have been more than pleased with this computer overall and the battery. I have not taken very good care of the battery and it's still kicking decently. I am at a cycle count of 410 right now which may not seem like a lot, but that's because I kept my computer plugged in all the time over the past 4+ years. It's also good considering the late 2008 MacBook's only have a Maximum Cycle Count of 300. I can get a little over 1 hour of web surfing time, if I try watching a movie on an external HD I only can get about 20 minutes. However as I said, I kept this thing plugged in ALL the time and rarely ever let it fully drain. I will probably purchase a Pro with Retina this year as the Max Cycle Count on those are at 1000, and I will definitely take care of this one. I'm willing to bet most of the people that had bad experiences with these batteries didn't take very good care of them like myself or perhaps it was just a defective battery. Either way I am pleased with Apple and the MacBook overall.

    Amazing Battery Life!

    • Written by from Prospect

    I have owned my 13-inch Aluminum MacBook for a little over two years now. The original battery is still installed in my MacBook. Below are the statistics from System Profiler for my particular battery:

    Charge remaining (mAh): 3923
    Fully charged: Yes
    Charging: No
    Full charge capacity (mAh): 3935
    Health Information:
    Cycle count: 420
    Condition: Normal

    The MacBook's battery life is still 4-5 hours with about a 1/4 screen brightness, and surfing the internet. I think this is quite amazing for a two year old computer! I love my Aluminum MacBook!

    It's still going on after 637 cycles @ 92%

    • Written by from Plano

    As an owner of an October 2008 Aluminum Macbook, I have to say that I've this battery longer than most people, adding to the credibility. To the review of this date, it's been 1 year and 7 months (or 19 months) since I've had the battery, and here are the stats:

    Charge Information:
    Full charge capacity (mAh): 3781
    Health Information:
    Cycle count: 637
    Condition: Normal
    Battery Installed: Yes
    Amperage (mA): 2063
    Voltage (mV): 11290

    It was only suppose to work after 300 cycles (which are full charge/discharges). 300 cycles is approximately 3 YEARS for the average user. As a college student & a techie, I use my battery alot and very well. I expected a dropoff of battery life right after 300 cycles, but nope! To this day, I still get approximately 3-4 hours, which I have the display on FULL BRIGHTNESS.

    In comparison, my original battery life was 4 hours to 4 hours and 45mins. If we do the math in terms of cycle count and time for the average user, my battery is AFTER 6+ YEARS (300 cycles = 3 years, so 637 cycles = 6+ years) only lost about 45 minutes of battery life.

    I can only imagine what the newer batteries of the Macbooks must be like. Apple produced quality products. Slightly pricy, but VERY WELL worth it.

    So far so good

    • Written by from Toronto

    Two years old now with approx 100 cycles and battery holds a good 4-5 hours charge depending on the programs running and brightness of the screen. I found that it helps to calibrate the battery when you first use it, then occasionally (some say once a week, I do it more like once every 2-3 months). According to specialists it is recommended that the laptop stays plugged in when possible, this way you prolong the life of the battery.
    Some people experience over heating of the battery, this will happen especially when running on battery power, and when several programs are open. This causes the battery to warm as well as the processor. There is a tiny fan that is desperately trying to cool the laptop down but it's not easy. To help that, try keeping the laptop in a well ventilated area, preferable on a flat surface rather than on a blanket or anything that prevents the heat exchange. Hope this helps.

    Only 4 hours charge

    When I bought this battery, I thought it would double my original (8 hour) battery life. Like it's advertised in here. But I only get 4 hours out of it. I'm really disappointed.
