Rating: 4/5 Revived 11" MacBook Air + Easy installation. October 30, 2017 I hav a habit of leaving my laptop plugged into power at all times. So, my battery life had been shortened substantially. This new battery will hopefully solve this problem.

I attempted to condition the new battery according to the suggested process at the end of the installation video. I believe I did it properly. And, by the way, the installation process couldn't have been easier. In fact, I was pleased to find that the new battery included the 2 different screwdrivers needed for installation!

I had hoped for all day use [8 hours] of my laptop without the need for external power. But, I feared that would be too much to realize. Of course, it was. My laptop only lasts about 3-4 hours before needing to be recharged. But, that is twice as good as it was before the new battery. Perhaps, I'll try to re-condition the battery again, in hopes of added battery time.

I would recommend this item to a friend!
