I was just wondering if I'm the only one not happy with the battery life on these things. I understand that all the digital decoding of protocols will probably drain the batteries at an even faster rate but still.. For high Mah rechargeable batteries I get 2-3 hours max. With Duracell AA around 4-5 hours max. Scanner and software are all updated to the latest versions. I'm monitoring around 700 conventional frequencies with analog, DMR and NXDN systems. Thanks a lot for any input!
