Rating: 5/5 Tools Included w/ Battery August 2, 2017 My heart sank when I watched the great OWC "how to" video about replacing the battery on my 2009 MacBook Pro - I was going to need a Torx Plus Security 6 screwdrivers. I had Torx, but the + security part means that you are dealing with a 5 sided star torx screw. @#$%, where was I going to find that tool? I looked online and discovered they are not easy to find. Dejected, I opened the box containing my new battery and and was stunned. NewerTech INCLUDES THE SCREWDRIVERS you will need for the entire job (including the Torx). THANKS NewerTech for making sure I had the tools I needed, and thanks OWC for a great "how to" video.

Rating: 5/5 Perfect Fit September 14, 2016 Quality battery, easy to install. When my 2nd Apple battery started to go south. I bit the bullet and decided to install my own using the Newer Tech replacement. It was easier to install than the 1 TB hard drive I installed a couple of years ago and came up with a health of 101%!

Rating: 5/5 Great replacement, everything needed is included August 13, 2016 I was a little concerned about making my own repair because the Apple store does not stock or install parts for machines over 5 years old. The replacement battery from OWC fit perfectly, came well protected in outstanding packaging with all necessary tools (special screwdrivers) and excellent instructions (including online step-by-step video). Also included were the recommended (easy) instructions for the multi- step protocol to recalibrate the charging system and maximize battery efficiency & long life. I was very impressed with the quality of every aspect of this repair experience and highly recommend it to anyone who can handle a screwdriver!!

Rating: 5/5 Better than the original May 20, 2016 I replaced the battery in my Mac Book Pro at the same time I replaced the hard drive with an SSD. The battery is an exact fit and has improved run time significantly.

I would recommend this item to a friend!
