Quick answer
The best refurbished AED for most buyers in 2026 is the recertified Philips HeartStart OnSite at about $875 with a 3-year warranty. It is the simplest AED to operate, the most widely stocked recertified model, and the same FDA-approved device as new. Choose the Philips FRx for schools and rugged sites, the ZOLL AED Plus for live CPR feedback, and the HeartSine samaritan for the most compact unit with the simplest upkeep. Judge every listing on cost per covered warranty year, not on sticker price.
Every page that ranks for this search is a product grid. They list eight refurbished AEDs, show eight prices, and never tell you which one to buy or why. Worse, almost none of them publish the number that actually decides the purchase: how long the refurbished warranty runs. We checked six sellers on the same day and found the identical model sold with warranties ranging from one year to four. This page ranks the models, names a winner for each situation, and does the arithmetic that shows why the cheapest sticker is often the most expensive purchase. If you are still deciding whether to buy refurbished at all, read refurbished vs new AEDs first. For what “recertified” actually involves, see the recertified AED guide.
The number that decides it: cost per covered year
Quick answer
Divide the price by the warranty length. A $875 AED with a 3-year warranty costs about $292 per covered year. A $775 AED with a 1-year warranty costs $775 per covered year. On that measure the cheaper sticker is more than twice as expensive.
This is the calculation no seller on this search performs, because most of them lose it. A refurbished AED is only as good as the promise behind it, and warranty length is the cleanest proxy for how much the seller trusts their own recertification. Here is the same model, same day, across sellers:
| Model (recertified) | Seller | Price | Warranty | Cost per covered year |
|---|---|---|---|---|
| Philips HeartStart OnSite | AED Leader | $875 | 3-year | ~$292 |
| AED Brands | $775 | 1-year | $775 | |
| Philips HeartStart FRx | AED Leader | $875 | 3-year | ~$292 |
| AED Brands | $725 | 1-year | $725 | |
| ZOLL AED Plus | AED Leader | $875 | 3-year | ~$292 |
| AED Brands | $725 | 1-year | $725 | |
| HeartSine samaritan 350P | AED Leader | $875 | 3-year | ~$292 |
| AED Brands | $705 | 1-year | $705 | |
| ZOLL AED 3 | AED Leader | $1,150–$1,295 | 3-year | ~$383–$432 |
| AED Brands | $1,095 | 1-year | $1,095 | |
| Cardiac Science Powerheart G5 | AED Leader | $1,225 | 3-year | ~$408 |
| AED Brands | $1,395 | 1-year | $1,395 |
Read that table once and the refurbished market stops being confusing. On every model checked, the listing with the longer warranty costs less per year of coverage, often by more than half. That does not mean the cheapest sticker is always wrong, but it does mean you should never compare refurbished AEDs on price alone.

The best refurbished AEDs, ranked
Ranked by how well each model suits the buyer most likely to be searching, using verified 2026 refurbished pricing and warranty terms.
1
Philips HeartStart OnSite (recertified)
Best refurbished AED overall
~$875 · 3-year warranty · ~$292 per covered year
The default answer for most buyers. The OnSite is the simplest AED made: no lid, pads pre-connected, one button, clear voice coaching. It is also the most commonly recertified model in the US, which means stock is reliable and pricing is competitive. At $875 with a 3-year warranty it beats the $775 one-year listings on cost per covered year by well over half. Full detail in our recertified Philips OnSite review.
2
Philips HeartStart FRx (recertified)
Best for schools, sports and rugged sites
~$725–$875 · 1 to 3-year warranty · from ~$292 per covered year
The FRx is the AED you buy when the environment is hostile: IP55 dust and water resistance, a body rated to survive being stepped on, and one pad set that covers adults and children when you add the Infant/Child Key. That last feature matters enormously for schools and youth sports, where a separate pediatric pad set is one more thing to buy, store and let expire. Confirm the Infant/Child Key is included before comparing prices. See the recertified Philips FRx review.
3
ZOLL AED Plus (recertified)
Best for CPR feedback and lay-responder teams
~$725–$875 · 1 to 3-year warranty · from ~$292 per covered year
The only widely recertified AED that measures chest-compression depth and rate and coaches the rescuer in real time. Most untrained rescuers push too shallow and too slow under stress, and Real CPR Help corrects that in the moment. The trade-off is running cost: it uses ten Type 123 lithium batteries and a CPR-D-padz electrode, both on roughly a five-year cycle, which is a higher consumable bill than a simple pad-and-battery model. See the recertified ZOLL AED Plus review.
4
HeartSine samaritan 350P / 360P / 450P (recertified)
Best compact unit and simplest upkeep
~$705–$995 · 1 to 3-year warranty · from ~$292 per covered year
The smallest and lightest FDA-approved AED, IP56 rated, and the only major brand that combines the battery and pads into a single Pad-Pak cartridge with about a four-year life. One consumable, one expiry date, one thing to track. That is a genuine advantage for sites without dedicated safety staff. The 350P is semi-automatic, the 360P is fully automatic, and the 450P adds a CPR Rate Advisor. See the recertified HeartSine review.
5
ZOLL AED 3 (recertified)
Best for connected AED programs
~$1,095–$1,295 · 1 to 3-year warranty · from ~$383 per covered year
The newest ZOLL, and the one to choose if you manage AEDs across multiple sites. A color touchscreen shows CPR feedback visually rather than only speaking it, WiFi reports device status to a program dashboard, and Uni-padz covers both adults and children with a single electrode set, so there is no pediatric pad to buy or track. Costs more than the $875 tier, and it should only win if you will actually use the connectivity. See the recertified ZOLL AED 3 review.
6
Cardiac Science Powerheart G5 (recertified)
Best fully automatic option
~$999–$1,395 · 1 to 3-year warranty · from ~$408 per covered year
The G5 is available as a true fully automatic unit that delivers the shock after a countdown with no button press, delivers that shock in 10 seconds or less after a CPR cycle, and runs a daily Rescue Ready self-check that shows a green indicator. Its non-polarized Intellisense pads work in either position. The honest caveat: those pads carry roughly a two-year shelf life, shorter than most rivals, so the long-run consumable cost is higher. This is also the one model where the lowest verified price ($999.99, 3-year) sits with a different seller. See the recertified Powerheart G5 review.

Which refurbished AEDs to avoid
Quick answer
Avoid any listing that does not state a warranty length, and always compare an older platform against a newer one before buying. One retailer lists a recertified Cardiac Science G3 at $1,395 with a 1-year warranty, which is more than a newer Powerheart G5 costs elsewhere with a 3-year warranty.
A storefront has no incentive to tell you which of its own products is a bad buy. Independent comparison can. Three specific traps we found in this market on 12 August 2026:
| Trap | What we found | What to do |
|---|---|---|
| Older platform priced above a newer one | A recertified Cardiac Science G3 listed at $1,395 with a 1-year warranty, while a newer Powerheart G5 is available at $999.99 with a 3-year warranty from another seller | Always price the newer model in the same family before buying the older one |
| No warranty stated at all | Several listings show a refurbished price with no warranty term anywhere on the page | Treat as sold as-is. Get the term in writing or walk away |
| Consumable cost ignored | Listings compare sticker prices while pad cycles range from about 2 years to about 5 years across models | Model the full 10-year cost, not the purchase price |

How to judge a refurbished AED seller
Quick answer
Ask three questions: is the unit tested on a defibrillator analyzer, are the pads and battery new and dated, and how long is the warranty. A seller who cannot answer all three is selling used, not recertified.
“Recertified” is not a regulated term, which is why the same model varies so much in price and warranty. The gap between a good and a bad refurbished AED is entirely in the process behind it. A documented recertification includes analyzer testing for correct joule output, a check that the firmware matches current AHA guidelines, new genuine pads and battery with printed dates, cleaning and inspection, and recorded expiration tracking so the unit stays in the manufacturer’s recall notification chain.
Watch for the tell: sellers who advertise a “10-point” or “18-point” process but never list the points. A named analyzer test beats an unlisted point count every time. Ask for the checklist in writing before you buy, and confirm the pad and battery expiry dates on arrival rather than trusting the listing.
Are refurbished AEDs safe?
Quick answer
Yes, when properly recertified. The device keeps its FDA Premarket Approval, and safety comes from correct shock output verified on an analyzer, in-date pads and battery, and current software. None of those require the unit to be new.
Sudden cardiac arrest kills more than 356,000 people outside hospitals each year in the US, and survival drops roughly 10 percent for every minute without defibrillation (American Heart Association). AEDs are Class III devices regulated through Premarket Approval (PMA), and recertification does not alter that approval. Schools, churches and small businesses deploy recertified units without a compliance downgrade. Placement still matters as much as the device: OSHA response-time guidance applies to refurbished and new units equally, and requirements vary by location, so check our AED laws by state guide.
Best refurbished AED FAQ

The recertified Philips HeartStart OnSite at about $875 with a 3-year warranty. It is the simplest AED to use, the most widely stocked recertified model, and the same FDA-approved device as new.
How much should a refurbished AED cost?
Between about $705 and $1,395 depending on model and seller. The common band is $725 to $895 for Philips, ZOLL Plus and HeartSine models, and $1,095 to $1,395 for the ZOLL AED 3 and Powerheart G5.
Is a longer warranty worth paying more for?
Usually yes. A $875 unit with a 3-year warranty costs about $292 per covered year, while a $775 unit with a 1-year warranty costs $775 per covered year. On that measure the cheaper sticker is more than twice as expensive.
What is the difference between refurbished and recertified?
Refurbished often means cleaned and resold as-is. Recertified means analyzer-tested for correct output, updated, fitted with new pads and battery, and warrantied. Always confirm the test record.
Which refurbished AEDs should I avoid?
Any listing with no stated warranty, and older platforms priced above a newer equivalent. We found a recertified G3 at $1,395 with a 1-year warranty while a newer G5 was available at $999.99 with three years.
Do refurbished AEDs come with new pads and a battery?
From a proper recertifier, yes, both new and dated. Confirm in writing before buying, and check the printed expiry dates when the unit arrives.
The one-line decision
Buy the recertified Philips HeartStart OnSite at $875 with a 3-year warranty unless you have a specific reason to choose otherwise: the FRx for schools and rough sites, the ZOLL AED Plus for CPR feedback, the HeartSine for the smallest footprint. Judge every alternative on cost per covered year, and never buy a refurbished AED without a documented analyzer test and a warranty in writing.
