IPG Battery Life
The rechargeable battery in the Precision Spectra System IPG should provide at least five years and
up to 25 years or more of service.
Over time, the IPG battery will need more frequent recharges. Like all rechargeable batteries, use
over time and repeated recharge cycles reduce the maximum charge capacity of the IPG battery.
1. The expected years of battery operation are defined as the longer of either:
A. Typical case: the time at which therapy cannot be maintained with daily charging
OR
B. High energy case: when the maximum recharge interval has decreased by more than 50 % from the initial recharge interval.
2. This estimated recharge interval is based on the following assumptions:
• The Precision Spectra IPG is newly implanted and at the beginning of it's charging life.
• The IPG has been programmed to the following settings: Current amplitude: 4 mA; Pulse Width: 300 μs; Pulse Rate: 50 Hz and Impedance: 750 Ohms.
NOTE: Your actual settings may vary, thus varying the number of days for your recharge interval.
