How is the battery replaced in the pacemaker?
The battery is sealed inside the pacemaker case, or can, which also contains the electronic circuitry. When the battery?s energy is depleted, a new pacemaker must be implanted. The surgery needed to remove the old pacemaker and implant the new one may require only a local anesthetic and is generally a very brief operation. In most cases, your original pacemaker lead(s) will not need to be replaced.
