Replacing Your Device

When it's time to replace the battery of your neurostimulator, you will need a new device to continue therapy.


The battery life of Activa® PC or Activa SC depends on how much stimulation you're programmed to receive each day. The average battery life is 3 to 5 years.

Activa RC, the rechargeable neurostimulator, is replaced after 9 years.


Your doctor will check the battery level and performance of your neurostimulator(s) at each appointment. You can also check your battery with your patient programmer.

Plan ahead and don't wait for your battery to run out before getting your device replaced.

Tell your doctor right away if you stop getting symptom relief, as the battery may have run out.


A surgeon will replace your neurostimulator(s) during a short, usually outpatient procedure. Typically, the very thin wires (leads) that were implanted in the brain stay in place and are connected to the new device.
