    Great battery

    • Written by from Lake Forest

    I have had no problems with my current battery... It is now over a year old and i still get about 3 hours on it...

    I will probably buy myself a replacement relatively soon so I can get a longer life. One thing I don't understand about previous reviews complaining about their battery dying is that this product has a one-year warranty, so Apple will replace the battery if it fails during the first year. Take it in to a store or call AppleCare and they will replace it straight away...

    Enjoy the battery.

    Fine for me.

    • Written by from Hillsborough

    18 months old, 389 cycles, 75% health, good for 2+ hours. It occassionally goes while still showing >20%, but deep discharging takes care of that for a while. Seems the older it gets the more important deep discharging is to keep the indicator accurate. Not happy with the cost of a replacement, but that's been true with any laptop I've owned.

    Not Bad...

    • Written by from Edmond

    I have an original (Gen. 1) MacBook and from day one I was careful about how I let my battery charge, and by last october I had 500 cycles with 80% health. Then I sent it to Apple to get my screen fixed and they replaced it! Life's pretty good.

    Par for the course...

    • Written by from natchez

    As far as laptop batteries go, this is about par. Rechargeable batteries, by their nature have to be replaced about once a year with regular use. Why? Well, the scientific answer would be that the chemicals inside the battery that are used to hold a charge, are, at first, seperate entities. However, as you charge the battery, drain it, etc. those chemicals that were originally seperate start to mix and bond to one another at the molecular level. The more they bond, the less charge they hold. This is normal. No I don't like it any more than you do, but here's a hint; other than the measures mentioned in previous reviews(brightness, volume, etc.) try unplugging your power chord as soon as you can, unless you are using power. If you are just charging the battery, unplug as soon as you get full charge. Even when your battery is charged, if you are still plugged in, the chemicals in the battery will continue to bond, just as if the battery was still charging.

    Try that.

    Macbook 13" Battery life

    • Written by from Rutherford

    I have found that every l-ion battery I have used for various devices are all subject to the plague of short life and run time if not "exercised" with 90% drain and %100 charging. As other reviewers have suggested, do not ping-pong the charging cycles.
    I am getting 3 hour runs on a charge at full brightness and with the screen saver off. At medium brightness, I get 3.5 to 4 hours of run time. I also turn off the audio if I do not need it. My Macbook is about 9 months old. I give it 4 stars only because the price seems to be a bit high. Could Apple offer a "faithful customer" discount?

    Great Product!! Not very good Product life...

    • Written by from Rochester

    I bought my macbook almost 18 months back. The battery life I used to get that time used to be 3-4 hrs as I'm a heavy user. Then around 6 months back I upgraded my ram from 1GB to 2GB. The battery life initially went down to 2 hrs and now its 1hr. I have no idea how this happened but know for sure its because of not charging fully and then discharging fully. So from now on I'll charge my battery fully until it shows battery charged and then discharge it fully until I get a battery low message. This should definitely improve the battery backup I'm getting. There are technical reasons for this phenomenon....

    Not a good idea

    • Written by from San Diego

    People who are saying you need to fully discharge the battery are telling you wrong. LiPo batteries are not designed to be fully discharged, and doing so can cut your battery life in half! The battery starts to deteriorate after about 300 cycles- not full discharge cycles mind you, but Apple defines a cycle as whenever you use 100% of your battery capacity,for example if you used 50%, charged to 100% again, then used 50%. NiCd batteries were designed to be fully discharged, but this new stuff is a lot different. All batteries start dying after about a year, its not Apple's fault.

    Oi, the battery.

    • Written by from carlsbad

    I would just like to say I have had something of a mixed experience with the battery. My wife and I ordered the macbook at the same time, over a year ago now. Her battery recently quit working. Mine works like new. The difference? She left her's on the charger 24 hours a day, whereas I unplug mine as soon as it is fully charged, then i leave it unplugged until the battery is about dead and needs to be charged again. Like one is SUPPOSED TO DO with ANY rechargeable battery. Rechargeable Battery 101: If it's charged, don't leave it on the charger or you'll fry it. Simple. My only real complaints about this battery are thus: 1. It's not idiot proof (and there are a *lot* of idiots in the world), and 2. Yeah, $130 is a tad bit on the expensive side, but I get it. If people have to have it and there's no competition, gouge, gouge, gouge! It's just good business!

    Battery Life

    • Written by from Warrenville

    It must be a problem with some serial numbers. I have a MacBook for 20 Months and I follow instructions for the battery almost every time. The only thing I did, is that if I store my computer for weeks, I always leave it 100%. My battery has 106 cycles (using Battery Logger) and it still shows good statistic numbers.

    Absurd expectations...

    • Written by from alpharetta

    I've had my macbook for over a year now... the macbook battery life isn't bad considering its size and number of processes being run on the computer at once. While most people consider it to be the brightness of display (which does have an impact on battery life) the greatest impact comes from how many programs are being run at once. While running Word, itunes, and medium brightness of display, I've still had about 3.25 hours of battery life with my macbook at any given use. Overall I would consider that to be a solid performance.

    The Macbook has a great battery. I don't have any complaints with it. It does last 4-5 hours as promised. However, if I just ran soley on my AC adapter, my Macbook would be running at reduced speed, which I was disappointed to learn.

    Okay product, but doesn't last unless you take certain steps.

    • Written by from Redding

    I have had my macbook for a while now, and have mixed feelings about the battery. It doesn't last very long, 4 hrs if the screen is bright, and unless I cycle the battery often (let it run down and then recharge) it loses its maximum charge. Some steps I take to prolong its life on a long trip is to a) turn down the screen as low as I can stand, and b) turn off the bluetooth and airport using system preferences. Using this I have gotten my battery to last five hours and forty-fifty minutes. If you plan on going on long trips, you will want this battery.(If you travel by car consider the car charger)

    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.

    Makes my MacBook Truly Portable

    • Written by from Snohomish

    You really need a second battery if you are going to try to work most of the day, out-of-reach from an AC outlet. This did the trick for me!
