LOAD_DISCONNECT_SWITCH

Deep discharge can damage a rechargeable battery. By disconnecting the battery from its load, this circuit halts battery discharge at a predetermined level of declining terminal voltage. Transistor Q1 acts as the switch. The overall circuit draws about 500 μA when the switch is closed and about 8 μA when the switch is open.
