For the Defibtech Lifeline or ReviveR VIEW/ECG/PRO AED
The DCF-200 is the standard battery pack for the Defibtech Lifeline AED. With this battery pack configuration you will get up to 5 years standby life. The Defibtech Lifeline AED battery pack contains a replaceable 9-volt battery to power the AED's daily, weekly, and monthly self-checks so that none of the main (life-saving) battery power is used on anything but saving lives. Once this main battery is drained the AED unit will not function. You might consider acquiring a fully charged spare battery to ensure the most prepared AED program.
