Had that happen with a Mag-Lite flashlight recently, using cheap "Ultralast" alkalines. The flashlight took a tumble, and became intermittent. Thought I'd broken something within the flashlight, but when I took out the batteries, the tabs on top of the Ultralast D-cells had been pushed in (not all the way, but definitely noticeable). Put in a fresh set of batteries, and the flashlight started working correctly again.
