    • Use Multimeter to test the voltage of the battery.

    • Put the black lead into ground slot of multimeter and the red lead into the V(ohm)mA slot.

    • Place the red and black leads to the two outside metal plate, each on opposite sides, on the battery as shown.

    • Check that the voltage displayed on the multimeter matches closely to the voltage defined on the battery. Normally 3.7 V.

    Have in mind that a 100% charged Li-ion battery can measure up to ~4.2 V

    Make sure it’s on Direct Current (DC) and probably 20V.
