How has a pacemaker made a difference in health care?
The pacemaker changed the world for medical reasons. Before, the 1st pacemaker would be portable and would have to be plugged into an outlet. This changed the population of people that have bradycardia. The pacemaker improved as the years went on. Later on it was implantable and had batteries. Today, the pacemaker also can be charged from the outside without getting surgery to replace the battery due to the new technology that we have today.

How do pacemaker batteries recharge?
First of all a pacemaker is a combination of two parts: the generator which contains the battery and logic, as well as the leads which connect to the heart. The batteries are not 'recharged'. When a pacemaker's battery is nearing the end of it's life (roughly 5-8 years) the patient schedules surgery, where the generator but not the leads are completely replaced. This isn't as drastic as it sounds and not usually as complicated as the initial fitting of a pacemaker. This operation is sometimes colloquially called 'recharging' but in reality the entire generator (battery and all) is replaced with a new one while the old is discarded.
How do you replenish acid in batteries?
