Self-Discharge: The dormant / self-discharge characteristics of Acebeam batteries are very low. This is one of the advantages of a lithium-ion battery with a control circuit. The battery life in dormant mode depends partly on the environment. High ambient temperatures, and higher humidity, increases the internal drain. But in normal circumstances, a battery installed in a device, like a door lock, will last ~12 months.
