Abstract
An implantable medical device includes a control circuit. A rechargeable battery is coupled to the control circuit. A battery monitoring circuit is coupled to one or more of the rechargeable battery and the control circuit. A telemetry circuit, coupled to the control circuit, is configured to transmit a battery status of the rechargeable battery to a first external device at a first time and to a second external device, of a different type than the first external device, at a second time.
