"Battery change" or "changeout" is a bit of misnomer. When the battery inside the device approaches the end of service life, it needs to be replaced. Since the battery is sealed inside a titanium case within the device, the doctor has to replace the whole device, not just the battery.

Since they are so small, leadless pacemakers are generally not removed when the battery runs low. Instead, when a new pacemaker is needed, the current device may be simply turned off before the new pacemaker is implanted. A doctor will determine what is best for individual needs.
