    Charging habits will contribute greatly to your battery's longevity. If your notebook stays fully charged at all times the battery will loose its ability to hold a healthy charge. Running your battery through its designed draining and charging cycles will ensure a long productive life for your battery! This doesn't mean you have to completely drain the battery to 0% before charging, in fact that is not a good idea!


    Standard Maintenance
    For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Apple does not recommend leaving your portable plugged in all the time. An ideal use would be a commuter who uses her notebook on the train, then plugs it in at the office to charge. This keeps the battery juices flowing. If on the other hand, you use a desktop computer at work, and save a notebook for infrequent travel, Apple recommends charging and discharging its battery at least once per month. Need a reminder? Add an event to Calendar on your desktop. When your battery no longer holds sufficient charge to meet your needs, you may choose to replace it. If your notebook came with a built-in battery, you should have the battery replaced only by an Apple Authorized Service Provider.

    Long-Term Storage
    If you don’t plan on using your notebook for more than six months, Apple recommends that you store the battery with a 50% charge. If you store a battery when it’s fully discharged, it could fall into a deep discharge state, which renders it incapable of holding any charge. Conversely, if you store it fully charged for an extended period of time, the battery may experience some loss of battery capacity, meaning it will have a shorter life. Be sure to store your notebook and battery at the proper temperature. (See “Notebook Temperate Zone.”)Notebook Temperate Zone. Your Apple notebook works best from 50° to 95°F. You should store them in places with temperatures of -13° to 113°. That’s 10° to 35°C and -25° to 45°, for the metrically inclined. Keeping your Mac as near room temperature as possible (22°C) is ideal.

    My current battery capacity is at 8051mAh after 133 charging cycles (17 months 5days). The full capacity when new was 8400mAh. You should expect to get 1000 charging cycles or about 5 years (depending on frequency of use) before your battery reaches 80% of it's original charging capacity.Charge Information:

    Don't think this battery will ever die!

    My current battery status speaks for itself. Bought late 2008 - 13 inch Macbook:

    Yep, that's right - 5 years, and 1890 full charge cycles and STILL keeps going!!!!

    Charge remaining (mAh): 3342

    If you let your machine run on battery after full charges, and drain it down to almost 'empty' most of the time before putting back on the charger, you will also get battery life like this!

    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!

    Learn how to use a rechargeable battery

    • Written by from Fort Wayne

    I bought my Macbook in 2009 and I haven't had to replace the battery yet. It now says "Replace Soon". Here are a few tips to make your battery last long than 1 year-as many consumers claim its lifetime is.

    -When you charge your battery, charge to completion
    -When the battery is charged, unplug it
    -Don't charge it unless it needs it
    -Calibrate it via Apple's instructions online regularly

    Following these easy steps will help you maximize your battery's lifetime. Your battery WILL deplete if you don't use it properly, its not Apple's responsibility to protect you from improperly using it.

    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.

    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.

    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!

    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.

    Take care of your battery!

    • Written by from Bobin

    It seems that there are a lot of negative reviews regarding this particular battery so I'm going to try and clear some things up. There are some things you can do to try and extend the life of your battery, the simplest of which is UNPLUGGING your laptop from the charger when the battery it's FULL. If you do this your batteries lifespan will last for years. Example, my laptop is still using it's original 4 year old battery and it's still running strong:
    Charge Information:
    Charge Remaining (mAh): 1724
    Fully Charged: No
    Charging: No
    Full Charge Capacity (mAh): 3637
    Health Information:
    Cycle Count: 1373
    Condition: Normal

    My guess is the people submitting the negative reviews have no idea how to take care of their battery.

    Don't Underestimate the Value of This Battery!

    • Written by from Guelph

    This battery was rated for 500cycles, but instead decided to give me 1437 before going to that great big battery field up in the sky. I didn't even practice the "good battery care techniques" that I've only now learned exist.

    As far as I'm concerned, that's great value.

    4 years and working great

    • Written by from Middleton

    As I was about to purchase a new battery, and after reading the reviews, I realized how lucky I am. I have been using my 2008 Late Aluminum MacBook unplugged for nearly 2 hours now, and I am at 70%, with 3 hours remaining. I noticed the review that suggested unplugging when fully charged. Although there were times I would leave it plugged in for a day or two, generally, it was left unplugged, so this may well be helpful after all. The price of the battery is rather steep, so I think I might just wait a little longer to order a second batter, just to have one on hand. I realize now that I confused the charge in this MacBook to the one in my IPad. Hey...I'm old, it happens.

    Unplug Your Battery When It's Charged!

    • Written by from Langhorne

    It's seems there are mixed reviews here so i'll add a positive one. If you actually unplug your computer when it's charged your battery lasts A LONG TIME! I had a roommate with the same computer bought several weeks apart and he needed a new battery after about a year. Why is this? because he never unplugged it, so when he did eventually his battery life was terrible. If you unplug it when it's charged it will work very well.

    Full charge capacity (mAh): 3883
    Health Information:
    Cycle count: 579
    Condition: Normal

    that's almost 600 load cycles on the original battery, with a 90% original capacity and the computer is 33 months old. That's just shy of 3 years.

    I've had this battery for almost 3 years, and as you can see above, over 1k cycles. I'm going to have to replace now, but based on the fact that it lasted this long, I'm not at all reticent to pay the $130.

    Honestly, the MacBook batteries are generally very well built. Mine has lasted me 3 years, I'm on 784 cycles and I can still get a solid 3 hours on it! Purchasing a second battery will only give me extra hours on my laptops life :)

    Needed to replace my battery as it was no longer holding any charge. I rang applecare and they told me i need to buy a new one from the store.
    My cycle count was 1187 which meant it went past the consumer able amount. I had a Macbook 13" Aluminium Late 2008. 3 years the battery has lasted me.
