The Dr interrogated his device, they will replace battery when it is time to. They are aware that the battery is low, they will schedule appointment to replace the battery in due time. I have a pacemaker/defibrillator with an audible alarm that times me the battery is low, and the device has about 1 month of battery life left. That s my signal to call the Dr. I m 100% pace dependent. I m on my fourth device but the skin in that area is thinning. Perhaps the Dr stated there is nothing we can do at this time ????
