But what can I tell from the above data sheet?
- Remaining battery life is on target to last me a few more years. At least 3 more, I hope. The Recommended Replacement Time (RRT) for my model of ICD is 2.62 Volts (see an estimated battery depletion curve here);
- The capacitor charge times remain excellent (around 9 seconds) and the capacitor reforming continues to be done automatically at every 6 months. Defibrillators use electrolytic capacitors to accumulate the charge before shock delivery and these types of capacitors require periodic recharging to reduce large leakage currents over time;
- The impedance of my leads (as measured in ohms, Ω) has been within range. A sudden increase in lead impedance ( > 2000 Ω) may indicate a conductor fracture, while a sudden drop in lead impedance ( < 200 Ω) may indicate an insulation breach.
