Abstract: The present invention proposes a method for operating a hearing device which prevents battery leakage, especially in the case when the hearing device 1 is powered by a mercury-free battery 2. The method comprises monitoring a supply voltage of at least one of a plurality of electronic units 7, 8, 9 of the hearing device 1, initiating a low battery leakage shutdown state when a low supply voltage condition is identified based on the monitoring, wherein the initiating a low battery leakage shutdown state includes activating at least one power gate 10 to disconnect at least one of the plurality of electronic units 7, 8, 9 from the power supply when entering the low battery leakage shutdown state, and discharging a buffer capacitor 4 provided for stabilising the battery voltage. Moreover, a hearing device 1 optimised for being powered by a mercury-free battery 2 is provided.
