    Steve Jobs would disapprove

    • Written by from Falls Church

    Just ordered my third battery in three years. First one died after a year. Second one expanded over the period of a week - to the point where the battery's case split, exposing the individual cells inside the casing. I have never seen batteries fail like these.

    The battery works very well for the first couple of months, but dies within a year and you have to get it replaced

    Mine Exploded - Almost Damaged Laptop

    • Written by from Saint Louis

    Even with proper monthly calibration cycling, mine expanded quite a bit. At the 2-year point, it was still holding over 2 hours charge. One day I noticed I couldn't use the click button. Removing the battery was the solution. Fortunately, I removed it before damage was done. The battery continued to expand, even after removal. I know that even Audi has a service department, but every auto maker issues recalls for defects that are dangerous, even after the warranty expires. Definitely going aftermarket for the replacement.

    Buying the same bad design for the 4th time and not happy

    • Written by from Farmington Hills

    Apple replaced my first battery for bulging and said they fixed the problem. Well the second one bulged as well, so I bought a third. Now after a little over a year, this one is bulging as well. I know many people change out their electronics after 18 months, but if you want to use a laptop for a while, this was not the computer for you. I wish they would at least make the replacement part better!

    Original bulged, Apple responded

    • Written by from Puyallup

    My 2008-era 17" MBP recently suffered the same fate as many have described here: Battery simply stopped working -- even though all indicators showed battery was fully charged and still fully functional, it wouldn't hold a charge. After less than 3 minutes on battery power, the MBP would hard-shutdown with no warning.

    A couple days later, the trackpad started to act oddly. A few minutes of online research had me checking the physical shape of battery: BULGING in the center. I made an appointment with the "genius bar" at the local Apple store the next day and preceded to dig up, and print out, all similar accounts of this happening. I highlighted all the cases where a local store replaced the battery for free.

    Turns out I didn't need all that research. The Tacoma store genius manager was my first contact and after one look at the battery immediately said, "we'll get you a new one right away." Five minutes later I was out the door with a brand new battery, no charge, no fuss.

    These are dangerous!

    • Written by from Louisville

    I am on my third battery. The first one fully swelled and sparked enough to leave scorch marks on my MacBook Pro 17. The swelling broke the screen and bent the case. Apple had to replace nearly the whole computer.

    The second time this happened, the Genius bar employee told me that a battery swelling was part of what happens when a battery gets old and it's a sign I need to replace the battery (for a price).

    THIS IS FALSE! A swollen battery is a sign the safety circuitry has failed. If your battery swells, it is a safety concern. Make the Apple employee tell you Apple says using a swollen battery is safe. They will try to use words like "I wouldn't" "In my opinion", make them tell you what APPLE says. They will then replace your battery.

    2nd one battery not so good

    • Written by from Timmins

    My 1st battery lasted for three years, and the second only one. Not impressed at all with the 2nd one ordered direct from Apple. I did the calibration faithfully every month and still (in my view) didn't help. That being said I DID NOT remove the battery when MacBook Pro plugged into power.

    The worst battery

    • Written by from Chicago

    I've had my MacBook Pro for a little over 3 years and I'm going through my second battery. This one, with only 30 cycles, has a 55% "health" rating. In other words, it's trashed already (and it's proved it is). In three years, I now need to get a third battery.

    I wish Apple would get decent batteries for their MacBook Pros.

    Another one bites the dust!

    • Written by from Winter Park

    My battery just went this afternoon. I hadn't realized until reading here, but the mouse and some of the keys were sticking and/or not responding when pressed, until I took my exploded battery out. I had been concerned about the nuclear-hot base of the laptop, and had quit using the computer on battery power for a few weeks, until today. thank goodness it doesn't appear to have damaged the memory. Why so many dying batteries, Apple?

    Battery Bulges and Comes Apart

    • Written by from Portland

    My battery also bulged and popped open on one side. It is the original battery that came with the computer I purchased in December of 2011, so it is 3-1/2 years old. I see that several other people are having this problem, and I hope that Apple will investigate it.

    Battery explosion - MBP 2007

    • Written by from Belo Horizonte

    I see that several others are having the same problem as me. The battery in my MBP started to swell to the point where it opened like a flower. One of the cells is so great that one has the impression that the worst is yet to come. I wonder, with colleagues, if there exists some justification reported for the apple.

    17 inch MacBook Pro Battery

    • Written by from North Hollywood

    My computer just passed it warranty 3 year mark, and the battery is bulging out the back. I have complained in the last two years that the battery and/or computer runs really hot fast, so I got a fan for it to sit on, but the genius bar wouldn't do anything about the machine running too hot while it was under warranty. I hope the battery didn't ruin the computer!

    Sane bulging battery issue

    • Written by from New Milford

    I came home after the memorial day weekend to find my 2007 17" MBP was rocking on the flat surface of the table. Turned it over to find the battery was sticking out and the case has split open. I removed it and it actually got worse overnight. Right now it the battery case is warped and one of the cells inside has swollen so the case is split open.

    I came here to buy a replacement and see others with the same problem happening at the same age in the lifecycle. Apple can you investigate?

    Battle of the Bulge

    • Written by from Columbus

    This bulging battery issue has happened to two of our computers in my department. Is Apple giving an explanation for this? I thought maybe mine had overheated in the cabinet where I lock it up at night, but my Lenovo PC lives in the same cabinet, and it is perfectly fine. Buying 2 replacement batteries now, and crossing my fingers that these don't explode. What happenend, Apple??

    Battery case splitting

    • Written by from Seattle


    This isn't so much a review, but I just wanted to reinforce the comments about this battery. In my case, the original is going on 3 yrs old and no longer holds a charge, I'm fine with that, it's lasted through a ton of cycles. But, after reading all the reviews, I realized that the reason my MBP was rocking when on a solid surface was because the battery was starting to bulge like others have noted. I took it out and also realized that the case around the battery was starting to split. I have since ordered a replacement.

    I'd suggest people inspect their 17in MBP batteries sooner rather than later.

    Bulging Battery from 2007 MBP

    • Written by from Olathe

    Wow! I thought the issue was only mine and caused from overheating. My battery from my MBP, purchased in 2007, is also starting to bulge. A few months ago, the computer started shutting down when plugged in and battery being around 63%. Just a couple of weeks ago, it's started to bulge, and is only getting bigger. My wife said today that she had to remove it completely because the trackpad was totally messed up with it in.

    I give the battery two stars because I was hoping it would last at least 4 years from my purchase date (sept, 07), which it almost did, and because when it worked, it worked well, but still, the warping issue and messing up the trackpad is kind of scary, and not lasting for longer when the battery health is still adequate is unacceptable. With all these bad reviews, one would think Apple would replace them for free, but I guess that's just wishful thinking. They did replace my faulty Nvidia vid card for free when outside of the 1 year Applecare plan, why not this when it is clearly Apple who is at fault here and not the end users.

    Embarassingly Poor Quality

    • Written by from Oviedo

    I bought one of these at an Apple retail store a few months ago to replace a buttery battery that had lasted me almost 3 years...

    Apple's first-rate replacement didn't even last 9 months or 400 cycles before it started to quickly fade into total uselessness. It doesn't hold a charge for more than 3 min now so I will be forced to buy yet another one or ditch my MBP.

    Judging by the rest of the reviews here, my experience is the rule and not the exception. I feel abandoned just like I did when I bought my 1st Gen Apple TV...

    What a shame.
