When the input is between UVLO and VIN(DT), the device enters sleep mode. After entering sleep mode for >20 ms, the internal FET connection between the IN and OUT pin is disabled, and pulling the input to ground will not discharge the battery other than the leakage on the BAT pin. If one has a full 1000-mAHr battery and the leakage is 10 μA, then it would take 1000 mAHr/10 μA = 100000 hours (11.4 years) to discharge the battery. The battery’s self discharge is typically 5 times higher than this.
