I haven't actually tested the batteries but my wife and I have used them quite a bit with no problems when I was outside and she inside or when we were both outside but out of sight of each other. The sound is clear and they are easy to use. The only thing holding me back from a five star rating is the lack of a separate belt clip (which stays on the belt like phone cases do. It's a bit difficult to fight against). on the belt or in the trouser pocket with a belt clip, otherwise great radios.
