Get longer battery life and improved laptop performance with a brand new Apple MacBook Pro A1286 battery.

This MacBook A1286 battery is only compatible with the MacBook Pro 15 inch laptop models listed on the bottom of this page, including models made between 2009 and Early 2011. Apple made two different generations of 15" MacBook Pros in Early 2011 which take different batteries.

Check your model number and the manufacture date to make sure you order the right battery. Your battery should match the picture above and the part number "661-5476". You can find the model number on the bottom of your MacBook. Additionally, check your MacBook's manufacture date by going to the Apple Icon and selecting About this Mac.

If your laptop was made in 2011, it is important to note that Apple produced two different generations of MacBooks. This battery is compatible with the model that was going out of production and the next generation was just coming into production. Here you can find the battery for the next generation of MacBook Pro 15" (early 2011-mid 2012).

To further complicate things, if the model printed on the bottom of the laptop is A1286, there are two different batteries that use the same model number. If your battery snaps into place, this is not the correct battery. This battery is only compatible with the internal battery in MacBook Pros. For the Snap-in battery, go to our Apple A1286 MacBook Pro (2008) battery page.

To replace the Apple A1286 battery you need unscrew the bottom of the laptop to access the battery. We include the required tools and instructions to remove and replace your original MacBook Pro 15" battery.

We use the highest quality lithium-polymer battery cells and components that charge faster, last longer and weigh less than cheaper, lower quality batteries. This 661-5476 battery is 100% compatible with the original Apple 15-inch MacBook Pro battery specifications and is individually tested, inspected and backed by a 2 Year warranty.

You can expect up to 4 hours of run time with this Apple A1286 battery when new, depending on your energy use. The higher capacity battery cells inside this cartridge have an energy capacity of 77.5 Whr.

This battery replaces the Apple 15-inch MacBook Pro (Aluminum) Unibody only from 2009 to 2011. This battery does not work with the 2008 15" MacBook Pro
