⚡ Maintenance Hack: Stop the Chirping!

Is your AED beeping? Many customers buy a new battery, but the device keeps chirping. This is often because the PADS are expired or not seated correctly.

The Philips OnSite performs a daily “Self-Test.” If it detects expired pads, it will chirp to alert you. Save time and shipping costs by replacing both consumables at once.

Frequently Asked Questions

Q: How do I find the expiration date?
The expiration date is printed clearly on the front handle of the cartridge. You can see it without opening the AED case. We guarantee to ship pads with fresh dates.

Q: Can I reuse these pads after opening?
No. Never open the hard cartridge case or peel the foil seal until a rescue is required. Once the seal is broken, the gel begins to dry out. If you open them “just to check,” you have ruined them and must buy a new set.

Q: My AED is beeping. Do I need pads or a battery?
It could be either. Press the blue “i” button on your AED. If it says “Pads Cartridge Damaged” or “Replace Pads,” you need this M5071A cartridge. If it says “Low Battery,” you need the M5070A Battery.

Q: What happens if I use Adult Pads on a child?
In a life-or-death emergency, the American Heart Association says it is better to use Adult pads on a child than to do nothing. However, for schools, churches, and daycares, you should always keep a specific M5072A Infant/Child Cartridge on hand, which automatically reduces the shock energy to safe levels.
