Electrode pads are stored in the back pocket, ready to apply. “Power On” and “Shock” buttons are oversized and brightly lit. Lightweight and durable. 4.2 lb. 5-year limited AED warranty, 3-year warranty on the battery pack, 1-year warranty on the 9-V lithium battery, and 2-year shelf life on the defibrillation pads.
