This is one of the oldest types of neurostimulators, the primary cell (non-rechargeable). The only model older than this one is the radio frequency system. For the unit shown here, you can expect the battery to last for 5 to 7 years. You will need battery replacement surgery when the battery dies.

This neurostimulator is also an option for chronic pain patients who prefer or require the simplicity of a non-rechargeable medical device.
