Despite the Samsung Galaxy S III shipping with a very respectable 2,100 mAh battery, it isn’t enough for some people. And there are plenty of options for extended batteries on the market, but we hadn’t seen any official ones. However, MobileFun posted a listing for an official Samsung extended battery kit. It comes with a beefy 3,000 mAh battery, almost the same size as the Galaxy Note II stock battery, and a new battery door to fit it in the phone.

But why get this over off brand batteries? First of all, you’ll be getting a legitimate battery door with the right finish and Samsung logos. It’ll match your phone. Second, it has the NFC contacts most custom covers lack, meaning NFC will function perfectly with this kit. And of course, it is official Samsung, which should speak for itself.

The kit comes in either white or blue and will set you back $64.99 including VAT. It’s a bit pricey but the matching battery door should be worth the money. Will any of you be getting this kit? Is it worth the premium? Tell us in the comments!
