This brand new 6JHDV battery for the AlienWare 17 R2 and 17 R3. This is an internal or integrated battery and you will need to unscrew the back case in order to install the new battery. A small phillips head screwdriver is all you will need to open up the case.
Note: This battery is not the correct battery for the M17x R1 or M17X R2 models (revision 1 or 2). The Alienware 17 is a different family of laptops than the older M17X family of laptops.
This Alienware 17 R2 battery is 100% compatible with the original Alienware battery specifications and is individually tested and backed by a 1 year warranty.
