Samaritan® Defibrillator Replacement Pad/Battery Set


HeartSine has taken an innovative approach to maintenance items by incorporating the AED electrodes and batteries into one single-use cartridge called the Pad-Pak™. The advantage to the Pad-Pak is that there is only one date to monitor and only one item to replace upon expiration or after use.

The Pad-Pak is suitable for use on adults and children. For children younger than eight years or weighing less than 25 kg, HeartSine offers the Pediatric-Pak™. The HeartSine PAD’s built-in intelligence and unique Pediatric Pad-Pak ensure the appropriate energy level is delivered for children.

Each Pad-Pak/Pediatric-Pak has an industry-first four-year life, and provides 60 shocks or six hours of continuous monitoring. When battery power is down to ten shocks or less, the HeartSine samaritan PAD emits an audible beep.


  • Adult Pad-Pak  - grey in colour, for use on patients from eight years old to adults weighing more than 25 kg
  • Pediatric-Pak -  pink in colour, for use on patients younger than eight years of age weighing less than 25 kg.

Great fit, quick delivery, fantastic packaging

Ordered these as a replacement for my clinic's AED. Super helpful and easy to reach customer service. Knowledgeable about the products they sell. Best pricing for this replacement as it was $70 cheaper than the usual retailers I order from. Fantastic, fun packaging and on time delivery. It was nice that the photos they have online are the actual product and very descriptive so I wasn't left having to do extra research on their website. Definitely going to look here first for future products!
