Question: How long does the pulse generator battery last? Rev. 03/03
Answer: Battery longevity varies depending upon the parameter settings and number of hours the pulse generator is turned on each day. Estimated longevity is about five years at typical settings, 16 hours of use per day. When the stimulator battery needs to be replaced, the surgeons implant 2 new pulse generators into the chest to replace the existing units. This can be done under local anesthesia but more often than not is done under general anesthesia.
The delicate brain surgery involved in placing the electrodes need not be repeated, nor are the extension and leads replaced.
