Allows a standard, inexpensive, easy to find battery to power your older HU1 or HU2
Power up your handset 1or 2 with the same batteries used on the new handset 3. Save money, time and reduce the number of different batteries and chargers you need to carry around. Why wouldn't you choose a battery that is 3 times lighter? Or lasts longer? Or is half the size, has an instant "Power Level Indicator", is more easy to get and is just as reliable? We don't know either. For the cost of a single battery from the original manufacturer, you can get our Adaptor AND a battery. It pays for its self on the first purchase! Then you can save up to 85% on batteries in the future! Our F.I.Z. Battery Adaptor snaps seamlessly on to your handset for a natural fit and an effortless battery swap.
