Battery Longevity Graphs
The following figure shows the estimated battery longevity of a newly implanted IPG.
Figure 7. Estimated battery longevity by energy factor for Proclaim™ IPGs (from time of implant)
The following figure shows the estimated longevity of an IPG battery after the low-battery
warning—also called the elective replacement indicator (ERI)—first appears on the clinician
programmer app or patient controller app when the battery is approaching its end of service.
