Actually the 396s were not mentioned in the discussion until now, I thought the Question was about an HP-1. The supplied Uniden batteries in my 396s were not of the same quality and I have replaced them a number of times.lep, thanks but your infomation is not correct. I have the 2900MAH batteries and they last a lot longer than the batteries that are provided by Uniden, I have used them in my Uniden 396T and my Uniden 396XT. I will be putting them in my Hp-1.As a ***Professioanal Scanner User.***I carry my scanner with me all the time and depend on the scanner letting me know what is going on and keeping me updated.
