AED pads are made for one machine, and often for one model of that machine. Adult and paediatric pads are not interchangeable, and pads from one make will not work in another. Start with the make and model on the front or the back of your AED and the page will show only the pads that fit it.

Every set of pads carries an expiry date, and a used set cannot be reused. Keeping a spare set means the machine is back in service straight after a rescue. Some makes combine the pads and the battery in one pack; those appear here and in AED Batteries.
