The ZOLL AED 3 launched as the spiritual successor to the AED Plus: same core architecture, Wi-Fi connectivity, full-color rescue screen, and a unified Uni-padz pad set that works for both adults and children. The retail premium is $317 ($2,399 vs $2,082 at AED Leader, checked 24 September 2026). Both are FDA-approved (PMA): AED Plus P160015, AED 3 under supplement P160015 S001 (28 Feb 2020). For most buyers, the question reduces to whether the color screen and Wi-Fi feature set justify the price gap.
Both share the foundational ZOLL value proposition: Real CPR Help® real-time compression depth and rate coaching, the industry’s longest pad shelf life (5 years on the AED Plus’s CPR-D-padz, 5 years on the AED 3’s Uni-padz), and 5-year battery cycles.
Quick answerBuy the AED Plus for single-AED budget buyers, simple offices, and any facility that does not need Wi-Fi remote monitoring or pediatric capability from a unified pad set. Buy the AED 3 for fleet programs (5+ units), mixed adult-and-pediatric environments, facilities with central program management, and gyms wanting the color rescue display.
ZOLL AED 3 vs ZOLL AED Plus: which to buy
Buy the ZOLL AED 3 ($2,399) if children may be treated or you manage several sites: one CPR Uni-padz set covers adults and children and WiFi reports readiness. Buy the ZOLL AED Plus ($2,082) for an adult-only site on a budget; it has the same Real CPR Help. Recertified: AED Plus $875, AED 3 from $1,150 (AED Leader, checked 4 October 2026).
Battery: the AED 3 battery lasts up to 5 years in standby ($201); Uni-padz also last 5 years ($234). The AED Plus runs on 10 off-the-shelf CR123A cells.

The Uni-padz pediatric advantage
The AED Plus uses two separate pad sets: standard CPR-D-padz for adults, and Pedi-padz II for pediatric. The pads are not interchangeable. The rescuer must physically swap pad sets during a pediatric rescue. For mixed-population facilities (schools, family fitness centers, places of worship), this is operational overhead and a documented failure point under rescue stress.
The AED 3 uses ZOLL’s Uni-padz: one universal pad set that works for both adults and children. For pediatric rescue, the rescuer applies the same pads in modified placement (one front, one back) per the device’s screen instructions. The device adjusts shock energy automatically. No swap workflow. No separate cartridge to track.
For facilities with potential pediatric rescue, the Uni-padz architecture is a meaningful workflow improvement.
The Wi-Fi fleet management value
The AED 3 includes Wi-Fi connectivity for integration with ZOLL PlusTrac, a centralized fleet management platform that monitors device status, tracks pad and battery expiration, alerts on failed self-tests, and provides post-event ECG data download. For organizations managing 5+ AEDs, PlusTrac removes a manual tracking burden that defaults to “miss it until you need it.”
For single-AED programs and small businesses, the Wi-Fi feature is unused. Most don’t have the IT infrastructure to integrate, and program scale doesn’t justify the platform overhead.
Rescue screen UX
The AED 3’s full-color screen displays large-icon rescue instructions, real-time CPR feedback metrics (depth bar, rate timer), and post-shock status. The AED Plus uses text and status icons, clear but less visually rich.
For high-turnover environments and lay-public deployments, the color screen matters. For trained-team environments where the rescuer is already familiar with AED workflow, the difference is marginal.
Real-world deployment scenarios
Scenario A: 12,000 sq ft commercial gym, 1 AED, adult members only
Trained staff (personal trainers, front desk). High SCA risk during exertion. Single AED program. Recommendation: ZOLL AED Plus. Real CPR Help® is the priority, and present on both devices. The $317 saving funds CPR training renewals; sites that drill in-house add the matching trainer (AED 3 Trainer $842, AED Plus Trainer 2 $481 at AED Leader). No pediatric requirement. No fleet management needed.
Scenario B: 5-school K-12 district, 12 AEDs total, central facilities management
Mixed adult + pediatric. Central program coordinator. Annual compliance reporting required. Recommendation: ZOLL AED 3. Uni-padz removes the pediatric swap workflow across all schools. PlusTrac centralizes expiration tracking and self-test monitoring across the fleet. The $317 premium per device, and $527 across ten years of consumables, is justified by district-level operational savings.

Frequently asked questions
Which ZOLL AED is best?
For most buyers the AED Plus at $2,082, because it delivers the same Real CPR Help® depth and rate coaching as the AED 3 for $317 less. Choose the AED 3 at $2,399 when you run five or more units, when children may be patients (one Uni-padz set covers every age), or when you want Wi-Fi readiness for PlusTrac. Prices checked at AED Leader on 20 September 2026. Professional BLS crews take the AED 3 BLS, which adds an ECG display.
Is ZOLL AED Plus good?
Yes, on one measure in particular. It is the cheapest AED sold in the United States that measures actual compression depth and tells the rescuer to push harder, rather than playing a metronome. It runs on a single CPR-D-padz electrode with a five-year shelf life at $230 and a ten-pack of lithium batteries at $100, so the consumable cycle is two line items, not four. Against it: indoor focus, no Wi-Fi, and a separate Pedi-padz II set at $155 if children may be patients.
Which AED defibrillator is best?
It depends which failure mode you are protecting against, and the honest answer is not always a ZOLL. Untrained rescuers: Philips OnSite at $1,589, the only AED sold in the US without a prescription. CPR quality: ZOLL AED Plus at $2,082. Mixed adult and child sites: ZOLL AED 3 at $2,399 or Philips FRx at $2,099, both one pad set for every patient. Fleets that need remote status: AED 3. Tightest budget: HeartSine 350P at $1,411. Six questions and a recommendation: Find Your Perfect AED.
How long does a ZOLL AED 3 battery last?
Five years of standby life. The replacement is $201 at AED Leader on 20 September 2026 and the CPR Uni-padz carry the same five-year cycle at $234. Over ten years that is two of each, which is where the real gap shows: $2,399 + $468 + $402 = $3,269 for the AED 3, against $2,082 + $460 + $200 = $2,742 for the AED Plus. The color screen costs $317 up front and $527 over ten years.
Do both have Real CPR Help®?
Yes. The depth + rate coaching is present on both devices and is the ZOLL differentiator vs Philips and HeartSine.
Is the AED 3 worth $317 over the AED Plus?
For fleet programs and mixed-age facilities, yes. The Uni-padz alone justifies it. For single-AED adult-only deployments, no.
Can both be used on children?
Yes. The AED 3 uses Uni-padz that work for both adults and pediatrics. The AED Plus requires a separate Pedi-padz II for pediatric use.
Does the AED Plus support PlusTrac?
No. Wi-Fi connectivity is exclusive to the AED 3 in the ZOLL consumer-class line.
Are rechargeable batteries an advantage?
For fleet programs with central management, yes. Fewer cells to track and dispose of. For single-AED programs, the difference is operational rather than economic.
Are both FDA-approved in 2026?
Yes. Both hold current FDA premarket approval, a PMA.
