Just installed a new battery from Anker. This tutorial was very helpful to me. iFixit was out of stock on the battery I needed, or I would have ordered from you.

Anker did include the special 5 prong tiny screwdriver needed.

I bought and installed the ifixit.com battery for my Mid 2009 15 inch MacBook Pro and it was easy and is working great. Much better than the dying battery it had. It was very easy. I did purchase the required tools which made it simple. Thanks.

Ordered the battery from iFixit, forgot to order the Pentalobe screwdriver. Nevermind, if you only do that stuff once (as I expect after 6 years with one battery) - don't spend the money on special equipment that cannot be used for anything else :)

Opening the macbook is easy (I have done that before to exchange the superdrive with a larger harddisk and the original HD with an SSD drive, and a couple of times to clean the fans), but the 3 screws on the battery are a pain.

What did the job for me: an old mini-flathead-screwdriver (approx. 2mm? - just slightly larger than the pentalobe) and a file. As none of my other screwdrivers would work with the ....pentalobes, i filed down the flathead (-)screwdriver so that it could get hold in 2 of the lobes - which did let me open and close these screws without a problem. My screws were not closed very tight though - if they are there is probably no way around the right tool.

Hello , I just replaced the battery on my macbook pro 15 inch 2009. Original battery was dead, would not even start without being plugged in.

I replaced the battery myself with one from amazon. Lizone is the brand. Laptop powers on now without being plugged in but after I enter my password it turns off, right after the login screen. Doesnt matter if its plugged in or not. I can access the login screen and thats it. When I removed the battery the laptop starts normal and I can get past the login screen and into el capitan.

I reseted SMC and PRAM multiple times. Is it a faulty battery ? What can I try?

Just finished using this guide to replace my mid 2009 MacBook Pro battery. Used a NUPOWER battery from OWC. Change went smoothly and I'll come back in a few days to update how it's working
