1. An aerosol delivery device comprising:
a rechargeable battery;
charging circuitry including an electrical connector configured to interconnect the rechargeable battery with a power supply;
a sensor configured to detect an action of using the aerosol delivery device by a user and output a signal; and
a microprocessor operatively coupled with the charging circuitry and the sensor, the microprocessor, in response to receiving the signal from the sensor, being configured to:
determine a state indicating a passage of electrical current from the power supply to the rechargeable battery through the electrical connector;
in response to the state indicating the passage of electrical current from the power supply to the rechargeable battery:
determine an output voltage of the rechargeable battery, and compare the output voltage of the rechargeable battery to a first low-battery threshold and a second low-battery threshold, the second low-battery threshold being less than the first low-battery threshold;
in response to the action of using the aerosol delivery device by the user and the output voltage of the rechargeable battery being less than the first low-battery threshold but greater than the second low-battery threshold, activate the aerosol delivery device so that power is delivered from the rechargeable battery to a further element of the aerosol delivery device to provide the output; and in response to the output voltage of the rechargeable battery being less than the second low-battery threshold, deactivate the aerosol delivery device so that power is not delivered from the rechargeable battery to the further element.
