Original replacement battery, for 15" i5 & i7 Macbook Pro from 2011. Note: when installing, be sure to reset your system's SMC immediately, as it may continue to register errors from your old battery.

Buying one of these batteries is fraught with anxiety. Apple does not sell them directly, and the aftermarket is filled with counterfeits. I do not have an approved Apple repair shop in my area. The reputable online sources for genuine parts do not have these in stock. Considering that a crap battery could do permanent damage to my laptop makes this purchase even more irritating. Arrgh!Thankfully, this battery arrived in a sticker-sealed static bag and appeared to be a genuine Apple battery. It is identical to the original battery I pulled from my early-2011 MBP. I had some doubts whether it is truly brand-new, since it has some minor scratches and smudges from an apparent wipe down. However, once installed it shows a full capacity of 6877mAh and has zero cycles, so I really don't care where it came from. It does the job.

I totally recommend this product, this is a genuine Apple battery made by SMP. I installed it on my Macbook Pro 15' early 2011 and worked perfectly, when I opened the bag it smelled like a new Apple product. A couple of days after installing Mountain Lion, my previous battery started to fail (after only 35 cycles in 17 month), first I got the "Service battery" warning and the next day, all of a sudden the battery completely failed and the operating system wasn't able to recognize it anymore (even though I did a SMC reset).This new battery works fine, it has a designed capacity of 6900 mAh but I get a maximum charge of 6925 mAh and 4 hours of battery life with normal use.Pros:- Excellent price- Genuine product- Perfect condition when arrived- Half battery already charged when arrived- Delivered pretty fastCons:- None |

Battery came in antistatic packaging, was OEM and works perfectly, no complaints here -- just make sure you know what you're doing while installing it, and have the right tools. I followed iFixIt's guide. You'll need a tri-wing driver to unscrew the two-three screws that secure the battery depending on your screen size. |
