If you are the proud owner of a Samsung Galaxy Nexus smartphone and would like an extended battery for your Android smartphone, apparently there is a new one coming onto the market shortly that will boost the life of your Android Ice Cream Sandwich handset, and that extended battery is the Mugen Power 4000mAh battery.

The Mugen Power 4000mAh battery is for the GSM Samsung Galaxy Nexus only and not the CDMA Verizon model, and is said to last up to 2.29 times as long, and is compatible with NFC.

The Mugen Power 4000mAh battery is a Li-ion 3.7v 4000mAh battery and comes complete with battery door with kickstand, and is CE approved, although the Mugen Power 4000mAh battery does add quite a bit of bulk to your Android smartphone.

However for those GSM Samsung Galaxy Nexus owners that would like to own the Mugen Power 4000mAh battery, the accessory is currently out of stock, but should be available in a few days and commands a price tag of $98.95.

We also have a close up look at the Mugen Power 4000mAh battery for the Galaxy Nexus, on video which comes our way courtesy of the guys over at Droid-life, so don’t forget to head on down and mash that play button…enjoy.
