An implantable medical device (IMD), such as a defibrillator, performs a capacitor reform or other temporary high current mode, such as to maintain efficacy of a battery or a high voltage defibrillation energy storage capacitor in spite of non-use. Before performing the capacitor reform or other high current mode, a voltage delay test can be performed. A voltage delay can be declared when an initial battery voltage measurement is less than a later battery voltage measurement during a loaded condition such as the charging of the capacitor. If a voltage de...
What is claimed is: 1. An implantable apparatus comprising:a battery;a high voltage storage capacitor for storing at least one of defibrillation energy and cardioversion energy;a high voltage storage capacitor charging circuit, coupled to the battery and the high voltage capacitor;a battery voltage measurement circuit, coupled to the battery; anda processor, coupled to battery voltage measurement circuit, configured to:recurrently test for a battery voltage delay via initiating a temporary high current mode that draws high current from the battery to det...
