Why Pacemakers Are Replaced
Pacemakers are electronic devices implanted in the human body.
They are also constructed to withstand changes in external and internal (body) temperatures.
The fact that the devices are sealed means that the batteries cannot be removed.

Instead, the entire pacemaker is removed and replaced with a new unit.
The current batteries used in pacemakers are manufactured to a high standard.
The premature failure rate of pacemakers is extremely low, generally under 1% after five years of use.
There are currently no pacemakers with removable or rechargeable batteries.
They can also monitor the rig remotely through a phone transmitter or the internet.
Usually, the rig provides warning signals several months before the battery runs out.
Some models beep when the battery is low.
It typically takes two hours to complete.
You will then be asked to return for a follow-up visit.
If non-dissolvable stitches are used, they will need to be removed in seven to 10 days.
This can make your heart beat irregularly, too quickly, or too slowly.
Summary
Pacemaker batteries have an average lifespan of five to 10 years.
Your cardiologist will check the battery level of your pacemaker with every visit.
There are usually built-in warnings to advise you when the battery levels are low.
Pacemaker replacement surgery is usually performed on an outpatient basis with either local or general anesthesia.
