Since UItraLITE headsets feature self-contained. "All in One" design all electronics, even the battery, is installed in the headset plastics. The batteries are lightweight and about the size of a book of matches. They charge in about 3 hours, run for 6 hours and can be changed out in seconds. Since they are Lithium-ion, the batteries do not have to be drained after each use and will never develop a memory.
Note: Batteries can not be shipped abroad
