Abstract
A battery-operated electronic device, such as, e.g., a continuous glucose monitoring (CGM) transmitter, has a switch disconnect circuit that reduces battery discharge while the device is stored and/or in “shelf mode.” The device has two externally-accessible activation pads each configured to contact a same electrical conductor positioned in packaging for the device that causes the switch disconnect circuit to disconnect the battery from device electronics while the device is in the packaging. Upon removal of the device from the packaging, the two activation pads no longer contact the electrical conductor, causing the switch disconnect circuit to automatically connect the battery to the device electronics. Methods of reducing battery discharge in a battery-operated electronic device and other aspects are also described.
