1. A method, comprising:
- transmitting at least one wireless command from a transmitter to a wireless electronic device, the at least one wireless command including a shut down command, the wireless electronic device including a battery safety circuit and is configured to receive a charge current from a rechargeable battery that is at least partially charged, the safety circuit being configured to protect the rechargeable battery; and
in response to receiving the shut down command, forcing a voltage at a port of the battery safety circuit coupled to a battery voltage signal to a voltage value that is configured to transition the wireless electronic device to a low power mode from a normal operating mode, the low power mode being configured to reduce battery self-discharge during wireless electronic device non-use.

Abstract
A wireless electronic device includes a rechargeable battery, a receiver, and a shut down module. The rechargeable battery is at least partially charged. The receiver is configured to enable wireless communications for the wireless device. The receiver is capable of receiving wireless commands configured to cause corresponding functions to be performed in the wireless electronic device, which may include test functions, calibration functions, and shut down functions. The shut down module is configured to cause the wireless electronic device to initiate a shut down protocol according to a shut down command received by the receiver.

6. A method in a wireless electronic device, comprising:
-
receiving at least one wireless command from a transmitter, the at least one wireless command including a shut down command; transitioning the wireless electronic device that includes a safety circuit to a low power mode from a normal operating mode in response to a receiving the shut down command to reduce battery self-discharge during wireless electronic device non-use, said transitioning includes forcing a voltage at a port of the battery safety circuit to a voltage value that is configured to transition the wireless electronic device to the low power mode, the battery safety circuit being configured to protect the rechargeable battery. - View Dependent Claims (7, 8, 9, 10, 19)

11. A wireless electronic device, comprising:
-
a shut down module configured to cause the wireless electronic device to initiate a shut down protocol according to a shut down command wirelessly received by the wireless electronic device, the shut down protocol configured to transition the wireless electronic device from a first operation mode to a low power mode configured to reduce battery self-discharge during wireless electronic device non-use; and a safety circuit configured to protect a rechargeable battery of the wireless electronic device and further configured to receive the shut down command to force a voltage at a port of the battery safety circuit coupled to a battery voltage signal to a voltage value that is configured to transition the wireless electronic device to the low power mode. - View Dependent Claims (12, 13, 14, 15, 16, 17, 20)
