    How can Apple not make this right?

    • Written by from Huntington Beach

    Now the 3rd one to bulge. Once the trackpad button stops working, you are out of luck and have a potential explosion on your hands. I am going to do the puncture method on my newly trashed battery and post it on YouTube with the countless others just to keep the discussion alive. Apple should fix this and provide free replacement batteries that actually last longer than 2 years.

    bulging, bent battery case.

    • Written by from Pincourt

    I've had to replace this battery 3 times. Every single one had the same problem. Even with proper battery care and cycling, every one has failed miserably. At around 225 cycles or about a year and a half, every battery I've had has stopped holding a charge and starts to bulge--breaking out of its own casing. A terrible battery... especially for the price.

    Fool me once...

    • Written by from Phoenix

    When my first battery swelled up and stopped working, I got a replacement battery. I got an official one from Apple, thinking that this would be the best option. Well, my second official Apple battery just met the same demise. This time, I’m gonna go with a cheaper alternative. I realize that it might not last, but it'll be a whole lot easier to replace the next time, knowing that I've only spent a fraction of the money for it.

    Need to purchase a 3rd battery

    • Written by from Kamloops

    the last two of my batteries bulged, it actually cracked my Speck hard cover case.

    With so many bad comments, I too, would think that Apple would have fixed the issue... Is it just bad batteries or is there something in the computer causing the batteries to do this??

    3rd Battery

    • Written by from Denver

    Well guys and gals at Apple, take a look at these reviews this battery issue continues to happen. I am now on my third battery with the same issue of bulging. Hoping something "bad" does not happen due to the compromised battery issue you know about.

    Defective Battery

    • Written by from San Francisco

    I am now on the second battery for my 17" 2008 vintage MCP. Both times the battery began to expand and interfere with trackpad function. Stores no longer stock so I have to get by mail order.

    Poorly designed battery and poor support from apple

    My 17" MacBook Pro battery started bulging one month ago. Called Apple and the service rep although very nice said there was no record of Bulging Battery issues; then I found out that there was a voluntary recall of I believe 1.8 million Batts not to mention the hundreds of comments on this site! Can't find them in any store within 100 miles of my city and online order through Apple says it would ship in 3-4 weeks! Very disenchanted with Apple right now. Buyer beware!

    Third battery! So what is it, a bad battery or is it the power supply that is frying the batteries?

    each one bulged at the three year mark

    • Written by from Rancho Cucamonga

    The first one bulged just before the three year apple care was up so they replaced if at no charge. the replacement batter bulged at three years and a month but it was out of warrantee anyway after an year.

    Doesn't Apple see all the one star ratings and feel embarrassed enough to do something about it?

    Since my first battery died, ive been EVEN more conscious of calibrating and cycling the battery every week or so. Regardless, my battery dies only a year later! If I need to buy a brand new battery thats over $100, every year, thats ridiculous, considering my PC has lasted longer without needing to replace the battery.

    I've now gone through two of these batteries, and Apple has no interest in replacing them or reassuring us that they have improved the life of them. With the recent crash issues Mac software has been experiencing, and now Apple hardware issues, like weak batteries, I think I might go back to PC.

    Since this was not my first Mac, I knew Macs run HOT. I have always kept my 2007 MBP on the best cooling pad made. Silly me, it only delayed the inevitable. I didn't know about the risk of the defective batteries. I would never have invested in this monster of a computer if I had. No warning-just in time for the 4th it blows! I feel betrayed.

    from "defective" to "design feature" according to apple, inc

    • Written by from San Jose

    the original batteries that came w/ this laptop were recalled (nor was it limited to apple batteries). at the time, i had no problem. however a year later, the battery bulged so that the trackpad won't work. pulled the battery out and left it sit for a couple of days. it expanded so much it quadrupled in size, twisting the case into an interesting shape. i took it to the local apple store. they looked at it, took it and gave me a new battery. no questions, no name, nothing. walked away happy. fast forward 2 years latter, the new battery did the same thing. this time the local apple store said this was 'normal' and a 'design feature' and that i either recharged the battery too many times or let it get hot. ah, no. same use pattern.

    so, what is it, 'design flaw' or 'design feature'? i know. why won't apple, inc say so now?

    treat a loyal customer since 1983 this way? for $129? bad apple, inc.

    Blow Up

    • Written by from New York

    This is the second battery to have exploded in the last five years. Both batteries still had a lot of cycles left. These are the worst batteries. The laptop always rested on a hard surface (i.e., desk) and never had a cold start, always room temp power up. Love the MBP, hate the battery.

    Bulging bust

    • Written by from Port Elizabeth

    First battery caused all kinds of funky things to happen to my MBP, before bulging and popping out the casing. Second one is 19 cycles old and near dead after being in storage for a year. I get better performance from 5 year old rechargeable AA batteries!

    2 Batteries have bulged within a couple months of each other.

    • Written by from Los Altos

    When I got my 17" MacBook Pro in March of 2008, I bought a second battery. I've religiously alternated them over the years approximately every three months. A month ago, I went to swap batteries and found my "spare" battery had bulged through the case to the tune of about 3 inches!

    A day ago, I noticed my trackpad clicker was hard to use...could barely depress it, but it would work. Today, it didn't work at all and if I tried using any part of the trackpad (including clicker), I couldn't select anything, either with the trackpad, corded mouse or bluetooth mouse.

    Upon removing the battery, I could tell it was beginning to bulge!! (My second battery.) The bulging battery, even though not apparent to the eye, was causing the trackpad malfunction.

    I've noticed there are many reviews about 17" MacBook Pro batteries bulging. Mine only has 173 cycle counts!

    Bulged and crackled

    • Written by from Inglewood

    I thought my battery bulged and crackled because I brought my mac into the warm house from my cold car…but I allowed at least a half hour for room temp adjustments, always do that. Looking at all the complaints here, I see I’m better off inventing my own external battery pac to use when I want to go mobil, otherwise I’m tethered to a wall socket anywhere USA.

    Bulged 'till it broke

    • Written by from Pinole

    First one bulged in the computer and was replaced by Apple at no charge at 97 cycles. Within two years the second battery stopped holding a charge with only 177 cycles on it so I removed it and bought a Newer replacement battery as Apple would do nothing about the other battery. That battery expanded and popped the shield off within a month of coming out of the computer. One cell on the end away from the power connector was huge while all the others were normal. Clearly some defective manufacturing in this particular battery line as I've never had this problem with any other Apple battery.
