I found that my favorite 3-D cell Maglite had the center battery corroded on the ends, and because Maglite tubes are only open on one end I couldn't push the stuck battery out. I poured about an ounce of Fantastik cleaner into the tube, shook it for a while, then let it sit and after a few minutes it had dissolved much of the corrosion and lubricated the exterior of the batteries and I could shake them out. If you try this, be sure to rinse and dry the inside of the flashlight tube before installing new batteries.
