Something is wrong with my battery that I got with my Compadre. It wont go dead. I have been using the same battery for 2 and 1/2 months now. I hunt 5 days a week in the mornings for 90 minutes before work. It still is going strong. The owners manual says 10 to 20 hours. I do use head phones. My luck, it will go dead the next time I turn it on. How many hours can you get with a battery????? KEN
