I would never buy one these again. The flashlight would not work unless it was plugged in to a usb port. I am totally disgusted.

  • BG132281016 This may help: the negative battery connection is through the enclosure
    to the edge of the pcb on top - a small ring of circuitboard with some solder,
    maybe 50 micrometers wide ! Solder some solderblobs around this edge
    and presto - it works fine ;-)

  • BG132281016 Ihave a possible solution for that: unscrew to top end of the battery holder - you'll find that the battery's negative pole through the spring and casing has a minimal connection to the
    bottom of the circular pcb: either solder a thin wire to the
    edge of this pcb ring and downside to the spring of the battery holder or just add three blobs of solder around the pcb ring -
    this works fine, no more erratic connection :-)
