Reviews for Rechargeable Battery - 15-inch MacBook Pro (aluminum)

My MBP is almost 4 years old and runs on AC power 90% of the time. I'm about to purchase the 3rd battery, as it only holds ~1300 mAh after 157 charge cycles. I religiously follow the protocol each month, as well.

My theory is that the MBP runs very hot and can't dissipate the heat efficiently. As heat increases battery performance but shortens life by a factor of two for every 10°C increase above 25–30°C (18°F above 77–86°F), the effect is degradation.

If I hear Apple engineers snickering at my naive analysis, I challenge them to better explain their faulty design.

I had the computer for a bit over a year and the battery hasn't even reached 500 cycles and now lasts less than half an hour. It seems that the only thing Apple hasn't nailed down is the battery issue. Offcourse its not like I could say "There is no way I'll buy another one" Because now I have no other choice but to buy another one in order to make my computer work.

My Macbookpro is 3.5 years old. The battery had been still in perfect condition in March. Then during a long flight in April,I watched HD movies on my macbook pro, and after about 1.5 hours the battery started to swell and I was unable to use my touchpad.

Ever since then,then battery became worse and worse. Today, it is NOT possible any longer to charge it.

I am sure macbookpro's battery could swell in flight due to less air pressure, and that is not restorable.

Love my computer, hate the battery. I have rarely taken my computer out of the house, and even more rarely run the computer on the battery alone. Both times have been on long airline flights. Very frustrating watching EVERYONE around you on their little Dell's gaming, playing movies, and generally having a great time while you sit with your MacBook Pro looking sleek and fine, providing about 45 minutes of battery life.
Have replaced the battery 3 times while under warranty and will have to replace again along with the power cord for the third time.

Brand new out of the box, first charge, it gets 2.5 hours (on the better battery performance setting). This is unacceptable. For reference, I'm using the first generation unibody pro from 2008.

Bought new in December 2008, already the battery still shows charge, but the seam on the unibody is bulging and the battery needs to be replaced. HELLO...SAFETY issue!

Not happy, but there is 150 bucks...

Had to replace the first battery because the old one swelled up so much I couldn't use the touch pad any more. The second one hasn't even lasted 6 months and now reports a "Service Battery" alarm. I'm happy with my MacBook Pro but I really wish there was another option for the battery.

This is a standard battery for the older MacBook Pro's. To the people complaining about not getting 8 hours of battery life, you are confusing different models. Up until at least late 2008, the MacBook Pro's had removable batteries which lasted 3-4 hours (2-3 more realistically). Apple never advertised these as having 7-8 hours. The newer models with the non-removable batteries are capable of lasting 7 hours, give or take an hour. The fact that these newer models have much larger internal built-in batteries is the reason why they last that long.

Once upon a time i believe I heard that these batteries can hold a charge longer than the original ones in 2008, which is my main reason for ordering one. I never got much time out of my battery but i also used my mbp constantly and intensively on high performance mode. i got about a two hours the first month then i never got more than an 1:30. just these past couple months my battery would only last for about 30 minutes. my battery got power cycled at least 3 times a week just from use, never on purpose, and usually more than once in a day. 830 cycles... id say i got good use out my 4 years, especially with how much i used it. never had any swelling either.

i think that most people probably leave their macbook charged all the time. thats not how batteries are supposed to be used. at least let them drain to 20% before you charge them again. if you leave your macbook plugged up all the time, what's the point of a battery? if you aren't using you macbook, dont charge it... keeping the battery charged with minimal use could definitely cause swelling... if i don't need it for a week, i don't charge it until i need it again. don't get me wrong, i leave mine plugged up sometimes for extended sessions but thats it.

i would like it to hold a charge for longer but thats the case with any battery. time to see if this battery is actually different.

bought a refurb mbp with a brand new battery 17 months ago and already i have to replace the battery, says the genius bar. didn't use the battery that much until the last 6 months. pretty lame that apple doesn't make a more reliable battery. *middle-finger*

the genius bar said they can replace the batter for $99. asked about the warranty on the battery and was told 90 days. then i was told i would get a 12 month warranty on a battery purchased online or off the shelf in the store. lame.

so now i have to shell out $129.00 on a brand new battery that will probably last about another 17 months of less than average use. lame.
