Review on NinjaBatt'S Longlasting Battery Upgrade For Apple MacBook Pro 15" [2011-2012 Models Only] A1286/A1382 - 10.95V/77.5Wh by Nate Eich

This battery comes at a 30-40% savings over other "official” Apple batteries. Must say I was skeptical but turns out for no reason. Battery fits perfectly in my 15” MacBook Pro late 2011. Nice fit and finish. Virtually identical to the original one. Even comes with the two screwdrivers you will need. Prior to installing this, my computer was barely able to startup (and sometimes it didn’t at all) even with the power adapter plugged in. Once I installed this battery the computer came to life and started in record time like it used to. Time will tell how long it will last. But I will modify my review if I encounter any issues. But so far so good!
