I don't have radio at home so I only use it at shows, let's see....over a two year period I have used my radio at about 5 shows, 3 days each, 8 hours a day if my math is correct that is about 120 hours of operating time, or 5 days and my battery is still running stong. I wouldn't be surprised if the battery would last a few weeks to a couple of months of continuous use.
I imagine it would also vary depending on the throttle, mine is a Digitrax DT100r, so other throttles with more functions may not last as long. What throttle are you using?
