If the battery is a non-rechargeable battery, this period varies between 4-6 years in proportion to the electric current supplied to the patient. In patients, the life of the battery is checked at certain controls. If the battery is almost dead, the battery placed under the skin in the chest is replaced with a half-hour operation.
Thanks to the developing technology in recent years, rechargeable batteries with a life of up to 20-25 years have entered clinical practice, and we apply externally rechargeable batteries to almost all of our patients.
