The Cardiac Science Adult Electrodes can be used on most Cardiac Science AEDs, including the Survivalink FirstSave, Powerheart AED (9200RD), Powerheart G3, and Powerheart G3 Pro. These electrodes are non-polarized so that both pads can be placed on either chest location (Apex or Sternum), making the rescue process much easier.
The CS 9131 Adult electrodes have a 2 year shelf life with the expiration date printed clearly on the front of the pad package. We recommend keeping a second pair of pads on hand in case multiple emergencies occur.
