Pulse Generator Life Expectancy Estimation (Implant to Explant) with EnduraLife Battery (All Models)

EnduraLife Battery Technology provides clinically proven, industry-leading projected longevity2-11. The following tables represent sample pulse generator life expectancy estimation (implant to explant) with EnduraLife battery as provided in product labeling. For specific programmable parameter ranges, contact Boston Scientific technical services or your local representative.

  • Assumes 70 PPM LRL; DDDR mode; 0.4 ms Pulse Width (RA, RV); sensors On, Heart Failure Sensor Suite On.
  • Projected longevity is calculated assuming 2 maximum energy charging cycles per year, including automatic capacitor re-forms and therapeutic shocks. These calculations also assume 3-channel EGM Onset is on and that the pulse generator spends 3 months in Storage mode during shipping and storage.

a. Assumes ZIP telemetry use for 2 hours at implant and for 40 minutes annually for in-clinic follow-up checks.

b. Assumes standard use of the LATITUDE™ Communicator as follows: Daily Device Check on, quarterly scheduled remote follow ups, and other typical interrogations.

c. Assumes LATITUDE™ Communicator is not used, Respiratory Sensor is Off, and Heart Failure Sensor Suite is Off.

Additional Longevity Information

  • Warranty information available at
  • Devices use Li/MnO2 chemistry.
  • The Usable Battery Capacity is 1.8 Amp-hours (typical implant to battery capacity depleted).
  • Shelf life is 2 years (before use by).
