What type batteries are used in pacemakers?

Answer 1

Early pacemakers were recharged using induction - similar to the way rechargeable toothbrushes are recharged.

However, today, with the advent of better and smaller batteries, they are simply replaced when required with a simple surgical procedure.

Answer 2

Pacemakers use litihium-iodide batteries. Although there are five major pacemaker manufacturers in the world, four of them get their batteries from the same source--Wilson Greatbatch. The one company that does not (Biotronik) makes their own batteries.

The technology is very advanced and allows for a predictable discharge curve, meaning that the end-of-life of the battery can be easily determined months in advance.

Most pacemaker batteries are a little over 2 volts.

Answer 3

Battery life typically ranges from seven to 15 years, depending on the number of leads the pacemaker is configured with and how much energy the pacemaker uses.

Answer 4

Doctors do it.
