Our first shipment of extended batteries for the 4082 just arrived and is now shipping. Why is this important? You will get 3.3X the battery life out of your MiFi. So, if you are currently getting 4 hours, now you will get 13 hours of portable internet access.
We have been selling the extended battery for the MiFi 2200 and it has earned 5 stars from customer reviews and we expect the same from this extended battery.
