  • Patent number: 10161576
    Abstract: An example apparatus embodiment includes a flashlight operable from a primary electric storage battery and from another battery having an external casing that has a different outer diameter and possibly a different overall length than the primary battery. In some embodiments, a battery adapter extends a battery compartment to hold a longer substitute battery. In other embodiments a batter adapter holds a battery with a dimension, for example a diameter of the battery case, that is too large to allow the battery to slide into the battery compartment. Another example embodiment includes a battery adapter without a flashlight.
