  • Open the case by hitting the edges with a hammer or similar tool and pry it open with a knife. (The red plastic is ultrasonic welded to the black case). Then remove the white LED, it has a little foam sticker on the back. Then remove the three screws, then the PCB. The battery also has a foam sticker on the back.

  • If the battery is too thick, then use a soldering iron to make a bit more room for the battery. Rub the iron on the plastic until the battery fits nicely below the PCB and the PCB rests on the three screw posts again.
