There have been a couple of questions about battery life with the 1080 so I ran a highly un-scientific test today. I picked a few depts. on the local RCS system for scanning, both analog and digital. I put in a set of 2500maH NiMh fresh off the charger and started scanning at 0826. I heard the first alarm at 1946. A little over 11 hrs. on one set of batts. That will work fine for me. I don't even need an extra set of batts. when going out for the day.
