6400mAH, this extended battery for the Samsung GALAXY Note II has 2.06 times the capacity of the stock battery and should last more than twice as long before conking out. The extended cell does have a larger footprint than the original cell, which requires you to use the special battery door that comes with the new battery. It does give your Samsung GALAXY Note II a little more girth, so to speak, but that's a small price to pay. Some people we know would sell their soul for 5 extra minutes of battery life on their smartphone.
The 6400mAh extended cell will be available for shipping on December 21st and costs $98.85. The rear cover comes in your choice of two colors, grey or white, so that it can match the rest of the phone.
