A mini Maglite is unlike a regular flashlight because it uses more powerful batteries to light its bulb. A battery can become defective and swell to larger than its normal size, getting stuck inside of the maglite’s battery compartment. You can remove a stuck battery from a Maglite, providing it is made of metal and you feel comfortable with the possibility that the casing might break. The Maglite will be useless as long as the stuck battery is still inside of it.
