    Drill a small hole in the base of an empty solder tube.

    Push tabbing wire through the base of the tube to make a sort of spring (inside the base of the solder tube).

    Use any type of sticky tape on the other end of the wire (the end outside the solder tube) to form a terminal.

    Fill the tube with 12 silver oxide batteries in series.

    The photos show 12 x 1.5v silver oxide batteries inside an old solder tube outputting 17.68v.

    Under a small load (for example the LEDs in a solar charge regulator), expect 15.5v @ 0.43 amps = 6.665 Watts for a short time.

    As the tube warms up, power diminishes due to equivalent series resistance (churning out more power than they were designed to provide).
