The Defibtech Lifeline Training pad package includes one set of training pads and a connector wire assembly in a sealed pouch. These training pads are meant for use with the Defibtech AED Trainer unit. The training pads are semi-adhesive, allowing for multiple uses and are non-functional so they cannot be used to deliver a defibrillation shock. The pads themselves can be replaced with DDP-105TR pads, which attach to the connector wire assembly with velcro.
