Recertified AED Checklist: 16 Checks Before You Buy (2026)

Quick answer: before you buy a recertified AED, confirm 16 things: an FDA-approved model that is still supported, a written analyzer test, new in-date pads and battery, current CPR prompts, a recall-clear serial number, a written warranty and return terms, and the ten-year cost. The most important three are the test report, new pads and battery, and a warranty of at least 1 year; AED Leader lists 3 years.

The 16-point recertified AED checklist

  1. The model is FDA-approved.Since 2015 the FDA has required AEDs to go through premarket approval (PMA). A recertified unit keeps its model’s approval; ask for the model number and check it is a current PMA model such as the Philips OnSite (P160029) or FRx (P180028).
  2. The manufacturer still sells new pads and batteries for it.A cheap AED you cannot restock is not cheap. Every model on our 10-year cost table still has new pads and batteries on sale.
  3. There is a written analyzer test report.The seller should test shock energy on a defibrillator analyzer and give you the result. Ask for it by serial number.
  4. The self-test passes when it arrives.Insert the battery, let the AED run its self-test and check the status indicator shows ready.
  5. The pads are new, genuine and in date.Check the expiry date on the pad package. Most pads last 2 years; ZOLL CPR-D-padz and Uni-padz last 5; HeartSine Pad-Paks and LIFEPAK CR2 pads last 4.
  6. The battery is new and in date.Check the install-by or expiry date on the battery label before you install it.
  7. The voice prompts follow current CPR guidelines.Ask the seller to confirm the unit’s software and CPR prompts are set to current American Heart Association guidelines.
  8. The serial number is clear of open recalls.Take the serial number from the unit and check it with the manufacturer and the FDA recall database. Our AED serial number lookup shows where the serial is on every model.
  9. The warranty is in writing, with its length.Recertified warranties at the sellers we checked run from 1 to 3 years. AED Leader lists 3 years on seven of its eight recertified models; get the term on the invoice.
  10. You know who fixes it under warranty.Ask whether repairs go to the seller or the manufacturer, and how long you would be without an AED.
  11. The return terms are in writing.Ask for the return window, who pays return shipping and whether there is a restocking fee.
  12. The case and housing are undamaged.Look for cracks, a loose lid or handle, a damaged pad connector and a clear status window.
  13. You know what is in the box.A carry case and owner’s manual are standard; a rescue kit, wall sign and inspection tag are extras some sellers include.
  14. Child pads or a child key exist for the model.If children could be present, check the pediatric option and its price before you buy (for the OnSite, M5072A pads cost $139).
  15. The prescription question is answered.Most AEDs are prescription devices under FDA rules and many sellers supply the prescription; the HeartSine samaritan PAD 350P and Philips HeartStart Home are sold without one.
  16. You compared the ten-year cost, not just the price.Pads and batteries can cost more than the device over ten years. A recertified ZOLL AED Plus costs $1,205 over ten years; a recertified OnSite costs $1,769.

Red flags: walk away if you see these

  • No test report, or the seller will not say who tested the unit.
  • “Sold as is”, or no written warranty.
  • Expired, used or non-genuine pads, or no battery date.
  • A discontinued model with no new pads or batteries on sale.
  • No serial number on the listing or invoice.

Recertified AED checklist FAQ

Are recertified AEDs safe?

Yes, when the seller documents an analyzer test, installs new genuine pads and a new battery, and gives a written warranty. A recertified AED is the same FDA-approved model as a new one.

How long is the warranty on a recertified AED?

It depends on the seller: 1 to 3 years at the sellers we checked. AED Leader lists a 3-year warranty on seven of its eight recertified models.

Do recertified AEDs come with new pads and a battery?

They should. AED Leader lists new pads and battery pre-installed on its recertified units; check the dates on arrival.

What is the difference between refurbished and recertified?

The words are not regulated. Recertified usually means tested against the manufacturer’s specification with a written warranty; refurbished can mean anything from cleaned to fully tested. Judge the unit by the 16 checks, not the label.

Is a recertified AED FDA-approved?

Yes. Recertification does not change the model’s FDA premarket approval.
