Reviews for Rechargeable Battery - 15-inch MacBook Pro

These batteries are terrible. I'm replacing mine every few months! I haven't been able to get more than 75 full charge cycles before they stop holding a charge. Is Apple selling me a cheap knock-off?!

I've had my laptop since may 2008. I always allow full charge then full drain as recommended. Now my computer will just shut off at anwhere from 20-45% battery life for now apparent reason and wont turn back on until it has been charging for a little while. I would understand if it got to under 15% or if it at least would display the message saying it is about to shut off but it doesnt. it is becoming extremely frustrating especially when in the middle of a report and it shuts off forcing me to startover. I will be getting a replacement aftermarket battery as the factory ones DO NOT LAST.

This is the second original Apple battery I have had in less than 3 years. The first battery I had lasted under two years and about 400 cycles. At it's best, it gave me a little over two hours of battery life. The next battery lasted one year and one day (and less than 100 cycles). I contacted Mac and they said that since it was beyond one year they wouldn't replace it (I'd complained earlier that the battery was defective as I never got more than an hour and a half of battery life). Piece of ****... getting an imitation now for half price and hoping for the best. No more Mac products for me.

To keep your battery life at its best, charged it to the fullest and used it until your computer runs on reserver battery when there is no ac plug-in around, then charged it to the fullest. If you're going to used the battery make sure you drain it then charged it back. If you're around ac plug-in, take the battery out of your MBP, THEN PLUG IN THE AC ADAPTOR, therefore the batter is out of the picture, and your battery will perform at its best with very low cycle. IT WORKS! There is no need to used the battery or leaving it attached to your computer when you are around the ac plug-in. Never charged it @90,80,70,60,50,40,30,20,10 % Always charged it @ 0%. Follow these steps and you will be happy with your battery and your MacbookPro.

Even following the battery maintenance schedule, the battery will claim to provide 4 to 5 hours. But this is only true if you turn on the computer and leave it alone. Using your computer will reduce your battery life to maybe 2 hours tops, a solid 90 minutes for sure.

I love my Macbook Pro but it is time for a new laptop and I am having second thoughts purchasing another Mac. I alway find myself envious of PC Laptops working for hours on their laptops while I am searching for a power outlet.

Horrible Battery, are you kidding; asking $129 for a under performer.

I am now on my third battery in so many years. I think it is real stupid that Apple has chosen to make batteries on their new computers built-in. They are so unreliable the computer will be in the shop getting a new battery again and again and again.

First battery died after a year. Replaced under Applecare. I had about 130 cycles. 2nd battery died another year later with only 44 cycles. Warranty denied since I didn't have the extended Applecare, so had a choice on 90-day warranty for $99 or a standard retail new battery for $129 with a year warranty. This one is dead another year later with about 50 cycles. At least this one will be a warranty. Thankfully I didn't take the offer to save that $30.

This battery isn't the best, but it sure does work. I have had my 15" macbook pro for over four years and i've only had to replace the battery twice. If that seems like too much, it's not. I'm just pretty demanding from my laptop. My latest battery is at 413 cycles, well over the amount it is rated for, and it still lasts almost 1-2 hours.

My only wish is that they would drop the price, even though 129$ every two years is definitely not the worst. It is much better than buying a new computer every two years.

Decent battery for the first 2 or 3 months then its health just tanks despite cycling it. I run my battery down often as well from daily use, and it still has a terrible lifespan.

I have the original battery in my 2007 MBP with over 500 cycles. It still holds a charge of over two hours fully charged and lasts much longer if I'm only word processing. It appears I got one of the few good batteries.
