It draws 1.2 nano amps when the "relay" pin is low and 6.5mA when the "relay" pin is high.
1.2 nano amps is roughly 3 million years of battery life for a standard 35AH battery. This was an important feature and it required that I design a tool specifically to test this.
This is the nano amp current sensor I design for this purpose.
