    I think so too. I think Spark should slightly lengthen the tube into which the battery fits. I put a ruler inside my Spark SD6-460NW in order to measure the depth of the tube. It was 68mm deep. My AW 18650 protected cell was between 66 and 67mm long. My AW 18650 cell sank 1 to 2 mm below the open end of the flashlight.

    I wonder if the Spark factory has ever varied the length of the tube into which the battery fits? If the factory has varied the length, it might explain why some of us have Spark SD6 flashlights with tubes which are too short, while others apparently have Spark SD6 flashlights with tubes of adequate length.
