    Cycle your Battery

    • Written by from los angeles

    If you follow the instuctions in the manual, and cycle your battery once a week. You can get about 4 to 5 hrs of battery life out of your mac book pro. i tried cycleing the battery and it really works and restores the batteries life. But the key is you have to do it once a week.

    Batteries Are Tricky.

    • Written by from Giggitymm

    Originally I was amazed at how expensive these things were from Apple, So I went the cheap route via Offbrand Amazon battery. Only to find out the battery would not charge, without the laptop being tilted, and one day I come home to the battery expanding and leaking. Amazon gave me a refund, But then I still didnt have a battery! So I bit the bullet and went to the apple store and picked up this battery. Works perfectly, after about a wekk I was getting 4-5hrs of life in my 2007 MBP. 4 Months later and no noticeable degration. Mine worked out fine, but there are lots of lemons. At least when you buy it at the store, you can just bring it back and get it replaced. NEVER BUY OFFBRAND!

    Some info for future

    • Written by from Newport

    Got my MacBookPro on eBay (new). 15.4" 2.16Ghz Core Duo, 1GB single DIMM DDR2, 256GDDR3 ATi x1600, 100GB Seagate 5400rpm HDD. It was manufactured in mid April 2006. The battery model is A1175 and it's serial number is ending with TY4B. Since I realise that the stated battery life is usualy no where close to the real life I had to test it. It works for 1.2 hours when under high pressure (playing games), just under 3 hours watching DVD's, and 3.25 hours is it's max life time. Not that close to 5 hours, uh?

    Dim your screen, unplug the adapter

    • Written by from West Jordan

    Dim your screen, save power, battery lasts longer. Apple displays are EXTRA bright. Dim it down a bit and it's still a beautiful display.

    Don't leave your computer plugged into the adapter all day, every day, and expect your battery to be unaffected. They last longer when the ions are moving around.

    My computer has been on for 2 years straight (seriously, I've never shut it down, only restarts). I go through about 2 charges a day and just now my battery is starting to wear out (though I can still get 2.5 hours, compared the 3.5 I was getting when I first got it, so it's not dead yet).

    Cycling DOES work!!

    • Written by from SAN DIEGO

    I just bought a new battery and decided to try the cycle idea. It works! So far, I get approximately 5 hrs of use. It is NOT false advertising! You just need to follow the suggestion! I am very happy with my purchase.

    I love my battery.

    • Written by from Redmond

    Google "lithium ion battery care."
    I've had my battery for over a year and it still keeps 3+ hours worth of life. I think the main thing is to not keep the battery in the computer if you are going to keep the computer plugged in. That's just like constantly discharging and charging the battery. It is kind of annoying if the plug gets knocked out, but at least I have the battery life when I need it. Sometimes, if I plug the computer back in fast enough, when I turn it back on it will have everything still open.

    Battery finally died

    • Written by from Grass Valley

    I just read all the reviews because I have to buy a new battery for my MacPro. I bought my laptop back in 2006 and it just died. I think it's lasted a long time. My only problem with the battery is I think it gets extremely hot. My husband's PC doesn't get hot at all but his laptop doesn't hold a candle to mine. I hope Apple can fix figure out how to cool down the battery.

    Not stellar, but not bad

    • Written by from Ames

    This battery will get 3-4 hours from normal usage (Airport, screen at 75% brightness, doing low-intensity work, no optical drive usage). Much better than my old 12" PowerBook, but definitely not as good as the first reviewer claims.

    cycling is the key

    • Written by from Charlotte

    For those whose battery doesn't work cycle it. Even if you screwed up and went three months without it. Start cycling every night for a couple of weeks. My battery needs to be replaced, but due to traveling hadn't had a chance. I was down to 15 minutes on a charge and realized I hadn't been cycling once a week like I should have. I cycled almost every night for two weeks and it's back up to over 2 hours of run time. Now, every time I cycle once a week a gain time on the computer. I still need a new one because I hadn't taken good care of it, but it tells you to do it. It's not perfect, but it is forgiving if you have patience. I am always on my laptop every day and run video and graphics for almost three years now.

    Its a battery, not a nuclear power-plant.

    • Written by from Medicine hat

    About 2 years of service for the original battery. Little low considering most batteries get a 1000 cycles before they are toast. My LG laptop got 3 years, but considering i use my macbook 5 times for every time i use my LG its understandable.

    Would have thought i'd see longer life span or a recondition feature for the battery for ease of maintaining its life. About the cost of a battery id expect maybe be nice to see it for 100$.

    It's a decent battery with the lifespan of about 1 year +

    • Written by from West Lafayette

    This battery would have lasted me longer if I didn't install Snow Leopard on it when it was half charged, beside the point you should cycle your battery at least once a week (I find it best to do it Saturday night, just let the battery drain then plug it in Sunday morning and your good to go.)

    If taken care of properly, it can last you a VERY LONG TIME!

    Battery is pretty good, but a bit expensive to replace.

    • Written by from Cochrane

    I have a MacBook Pro that has been running off the same battery for about half a year. It's been cycled nearly 200 times, and is down to 80% charge. However, that is fairly normal for batteries; After about 300 maybe 400 recharges the battery needs to be replaced. It helps if you fully recharge and discharge often, and reset your battery's chip every once in a while (recharge until full for 2 hours, allow to discharge until it goes into sleep and leave for another 5 hours or more, then recharge again. Original instructions somewhere on the apple site). Many people are upset that they only last about a year, but that's good; most laptops of similar size and power probably won't last that long. The only problem is that they're expensive to replace. Well, that's apple for you ;).

    For its size and life I would say it is a decent battery

    • Written by from Stoney Creek

    Most PC based battery last much longer now-a-days, but you pay the price of weight that come with the monster battery. If you want your MBP battery to have a good long life, it is plain and simple logic. When the laptop is done charging take it off the power cord, if you don't you will kill the battery in a short period of time. If you notice big drop in the health, then calibrate the battery and you will see improvement. Best advice, educate yourself about your MBP and your battery and you will be a happy MBP user.

    Misunderstandings about battery life

    • Written by from Oak Creek

    It seems most of these reviews are useless. It really depends on charge cycles. The analogy I'd use is it's like tires. If you put 80,000 miles on your car in one year do you complain your tires didn't last more than a year? No you just buy new tires. Same thing with batteries. If you go through 300-400 charge cycles in a year of course your battery isn't going to last long.

    Mac Book Pro Battery Life

    • Written by from Calgary

    My battery is 21 months old. It currently provides ~2 hours of power while running 4+ applications or the DVD player. In terms of cycling, I have not applied any particular regime; I plug-in whenever I can. The unit has performed flawlessly over 2 field seasons in a remote area of northern Tanzania, but perhaps my machine has been the exception to the rule.

    This review is not to promote the battery, rather it is to indicate that the inconsistent performances among our batteries suggests that Apple has had an issue with consistent quality. While Apple tends to produce superior machines, customer support remains wanting. I hope this discourse assists Apple in acknowledging a problem with battery performance, and that these issues are resolved.

    Characteristics of Lithium Ion Batteries..

    • Written by from Jacksonville

    People who complain of short battery life are overcharging the battery. These batteries like to be between 40 and 60% charged and when you keep them plugged in, it drastically reduces the life! So, only charge when you have to, and if you're at home using it like a desktop, take the battery out while your using it.

    Expesive, but works well

    • Written by from Akron

    I am happy with my purchase - I had to order a battery after my original laptop battery hit 300 cycles (1 1/2 years) and it's life did not last long. I ordered a new one because I am a student and I need my MBP to be portable.

    I would say that this battery is as good as the other battery, IF you properly take care of it. It's not just about the cycling. DON'T leave your power cord plugged in when your laptop is off and it's fully charged! Only when you're actually working on it. That will just ruin your battery.

    After 1 1/2 years of cycling almost every day or a few times a week, and never leaving the power cord in when it's not needed, my battery was still at about 4 hours, even with the Internet, but diminished after it's 300th cycle.

    Testing out this product, I am happy with it, but wish that we could get an 8-hour battery for our older MBP's. Mine replacement is lasting me 4-5 hours using the Internet and adjusting settings for better battery usage.

    Good, but no recharging dock..?!

    • Written by from San Francisco

    Good battery, enables me to swap in/out when I'm on the road so my computer will run for ~5 hours total.

    But I'd like to be able to plug in this battery directly to the wall while using my MacBook wirelessly roaming around my house. That way, I could drop in the recharged battery and keep roaming around without having to tether my MacBook to the wall. Basically I never want to have to plug in my MacBook again - I want to just keep swapping in recharged batteries so I can remain untethered from all electrical outlets.

    Unfortunately, this battery does not come with a recharging dock (and there does not appear to be a 3rd party solution available); the only way to recharge this battery is to have it in your MacBook and to have your MacBook plugged into the wall..! Very frustrating! Apple came so close to making this spare battery a truly superb, useful, and liberating product, but they blew it. So it's just 'good' not 'great.'
