Abstract
A method for determining a recovery voltage in a battery includes detecting a transient increased current draw event drawing current from the battery, the transient increased current draw event starting at a start time and ending at an end time; and in response to detecting the transient increased current draw event, waiting until time and/or voltage criteria are met to determine recovered battery voltage. An implantable pulse generator (PG) device for stimulating a human organ includes a battery, a power sink drawing current from the battery, wherein drawing increased current from the battery for transient periods causes battery voltage to decrease; and a status indicator detecting a transient increased current draw event and waiting a minimum time duration after the transient increased current draw event to measure battery voltage in order to determine a recovery voltage.
