I had my LVAD implanted on March 9,2018 and after six months in and out of hospitals I am finally getting back some energy. I had at least six alarms on my controller and no explanation on the screen. My battery was changed in the controller and the very next day an alarm. I labeled all 8 batteries and I am checking to see if one of the batteries is defective. Has anyone else experienced this problem?
