CPR Defibrillators offers two rescue packages which have the same Defibtech AED Defibrillator. The differences with these packages are in the battery's shelf life being 5 or 7 years. Both Defibtech rescue packages include defibtech adult pads, defibtech user manual, a quick response use card, and a 9 volt self test battery. This battery is for testing your  defibrillator each week.
