Zusammenfassung:	A device, battery and system to reduce battery leakage is provided. The system includes a battery, a battery-powered device, and an interface therebetween comprising cell contacts and a data interface. The battery comprises: a cell; a low-power protection circuit; and a high-power protection circuit configured to receive an indication via the data interface that disables the high-power protection circuit, leaving the low-power protection circuit enabled. The battery-powered device comprises: a high-power subsystem used when the battery-powered device is in an operating state; a switch between the cell contacts and the high-power subsystem; and one or more sensing circuits configured to, in response to determining one or more of a power-off state and a low-battery state: open the switch to the high-power subsystem; and transmit, to the battery, via the data interface, the indication.
