User question:
Battery Consumption per Interrogation in Abbott Aveir VR Leadless Pacemaker
General Estimation:
Battery Drain per Interrogation: 0.01% to 0.05% of total battery capacity per session.
Factors Affecting Consumption:
Length of the interrogation (5–15 minutes).
Whether reprogramming or testing is performed.
Telemetry power usage.

Final Takeaways:
Occasional interrogations (quarterly or less) have a negligible effect on battery life.
Monthly, long-duration interrogations could reduce battery life by over a month across 5 years.
Frequent interrogations combined with high output voltage settings (e.g., 3.5V or more) substantially reduce battery longevity.
