An AED with dried out pads or a dead battery is not much of a help. Statistics indicate that more than half of the public AEDs cannot be used, because they are not properly maintained.
Moreover, some outdoor cabinets have a poor reputation when it comes to their core function: keeping the AED safely within the storage conditions specified by the AED manufacturer. Overheated AED pads dry out and will not function when required. With frozen electronics or batteries, the manufacturer will not guarantee the functionality of the AED. The AED monitoring system continuously measures the temperature and humidity inside the cabinet, stores these data and provides warnings if storage conditions are not what they should be.
You will better understand the significance of this when you take a look at our AED cabinet Winter tests and Summer tests
