Jkno is right. I think I kept mine in for 2 weeks, after I got it, turning on the light on & listening to it off & on. Then I decided to take them out, as I was moving it to a spot harder to reach easily. To my surprise, the batteries were already beginning to corrode. I was NOT expecting that, as it was only 2 weeks out of the box.
Yikes, point taken!
