3600mAh Extended Battery & Cover for Novatel MiFi 2200 - Lasts up to 3x Longer than Standard MiFi Battery!
[HLI-MIFI2200XL]

The extended battery for the MiFi 2200 is fantastic. My whole purpose in getting the MiFi was to use it with an IPad so I could save the money and get the wifi only version. Well the included battery would have run out way before the Ipad would so this extended battery is the perfect solution. Now I have approximately 10 hours on the extended battery and another 4 hours on the original one that came with the MiFi. I can leave the MiFi in my pocket turned on and ready to connect all day then use my ipod touch like a cell phone with skype and google voice. I essentially have an iphone and a personal wireless network for about 40 dollars a month with no contract and it is really made possible by the extended battery and the MiFi unit (Virgin, otherwise you will pay 60 per month and be locked into a 2 year contract). The 3Gstore delivered outstanding service!!!
