I am planning on picking up a 396XT portable. I get conflicting reports from people who say it is a battery hog and some say it is not. I am going to use it mainly to monitor the CT. State Police 800 Mhz. digital system and nothing else, as I have 2 other portable scanners for analog monitoring. I use 2700 Mah batteries. I welcome your comments on the subject as it will help me make my decision.
