LifePak CR2 Essential Lithium Replacement Battery Batteries, pads and electrodes are all consumable parts of any defibrillator and must be replaced over time. When it comes to defibrillation electrode pads, efficacy, patient comfort and ease of use are vital to defibrillation/cardioversion and positive patient outcomes, the EDGE System electrode pads with REDI-PAK lets rescuers receive the best technology available on all counts. The Physio-Control REDI-PAK preconnect system allows electrode pad connection prior to use without breaking the package seal, saves valuable time at patient arrival, allows electrode pads to be pre-connected which eliminates time-consuming electrode pad changes and promotes continuity of patient care. It is recommended to always have a spare pediatric electrode with your AED in case of a second emergency
