Rating: 5/5 New life! September 2, 2016 I bought it for my Macbook late 2009.. And it brought new life to it! I even couldn't use my laptop without charger, every time when I unplugged it, my laptop just shuts down.. Apple support just told me that "there's nothing that we can do for you, cause your laptop is too old and we don't make new parts for it anymore..". Changing of battery was really easy and quick. Now it shows me that I have battery level for almost 4 hours on a max settings and 6 hours with save power mode. I'm going to calibrate my battery also and I hope the numbers are still gonna be the same ;) And it seems like I have brand new laptop (I also bought new memory 8gb and SSD 240GB)! I hope everything is going to work well and for long time! Thank you!

Rating: 5/5 Great March 21, 2016 Although this did not restore the macbook's original 7 hour battery life, this gives me a solid 3 to 4 hours of use before I have to plug it in. Needless to say, this is a great improvement after my 2 minute battery life with the old battery. Easy to install and it included the necessary tools.

Rating: 5/5 Works as advertised January 15, 2016 Perfect fit, keeps my laptop usable for many hours after a full charge. SO much cheaper than taking it to the store for service. I recommend it for anyone in need of a replacement.
