The verdict, in one line
What actually separates these two brands
Quick answer
Every comparison of these brands you will find lists specifications side by side and leaves you to guess which ones matter. Almost none of them mention the only variable with published outcome data attached, which is chest compression fraction: the share of the rescue during which compressions are actually happening. Survival tracks it. Pauses destroy it.
The two manufacturers attack that problem from opposite directions, and once you see it that way the choice becomes simple. One brand makes your compressions better. The other makes there be more of them.
The Hands-Off Gap, with the numbers
Quick answer
| cprINSIGHT measure | Result | Comparison |
|---|---|---|
| Pre-shock pause | 8 seconds | 22 seconds average, conventional AED |
| Chest compression fraction | 86% | 80%, conventional AED |
| Decision reached during compressions | 70% of cases | 0% by definition on a conventional AED |
| Shockable rhythm sensitivity | 95.5% | |
| Non-shockable specificity | 98.2% | |
| Validated population | Adults and children one year and older | |

What ZOLL does instead
Quick answer
This is the correction almost every comparison page gets wrong, including two currently ranking for this query. Real CPR Help is not exclusive to the AED 3. Both ZOLL models measure compression depth, which matters because untrained and even trained rescuers routinely compress too shallow under stress.
The trade is clean and worth stating plainly. LIFEPAK reduces the time your hands are off the chest. ZOLL improves what happens while your hands are on it. If your responders are trained and drilled, the LIFEPAK argument is stronger. If your AED will most likely be picked up by whoever is nearest, the ZOLL argument is stronger, because a shallow compression repeated for two minutes is a far bigger problem than a 14-second pause. Full detail in our ZOLL AED Plus review and ZOLL AED 3 review.

The 14-Second Question: what those seconds cost
Quick answer
| Model | Pads (price, life) | Battery (price, life) | 10-yr consumables | Cost per covered year, new |
|---|---|---|---|---|
| ZOLL AED Plus | CPR-D-padz $230, 5 yr | 10x 123A lithium ~$100, 5 yr | ~$330 | $241 |
| ZOLL AED 3 | Uni-padz $234, 5 yr (adult + child) | $201, 5 yr | ~$435 | $233 to $283 |
| LIFEPAK CR2 | Quik-Step $196, 2 yr (adult + child) | $341, 4 yr | ~$1,466 | $372 to $415 |
Our calculation. Replacements needed across ten years: CR2 pads at years 2, 4, 6 and 8 plus batteries at years 4 and 8. ZOLL pads and battery at year 5. ZOLL prices from AED Leader Aug 2026; CR2 battery $341, part 11141-000165, from aed.com Aug 2026 because AED Leader does not publish that part price. Cost per covered year = (purchase + 10-year consumables) divided by 10.
The driver is pad life. ZOLL’s CPR-D-padz last five years and the AED 3’s Uni-padz do the same; the CR2’s Quik-Step pads run on the industry-standard two-year clock, so you buy them more than twice as often, and each set costs nearly as much as ZOLL’s five-year pad. This is the number that should decide a fleet purchase, and it is absent from every other page ranking for this comparison. The full cross-brand table is in our AED pads and batteries guide, with brand-specific detail in the ZOLL AED Plus parts guide and the Philips parts guide.
Worth crediting to LIFEPAK: the CR2’s Quik-Step pads cover adults and children in a single set, so there is no separate pediatric purchase. ZOLL matches that on the AED 3 with Uni-padz but not on the AED Plus, which needs Pedi-padz II at about $155 every two years, roughly $775 per decade. If children are in scope, that closes a large part of the gap between the CR2 and the AED Plus. Our schools guide works this through at institutional scale.

Which one should you actually buy
Quick answer
| Your situation | Buy | Why |
|---|---|---|
| Home or small office | ZOLL AED Plus, recertified $875 | Cheapest decade at roughly $1,205 all in, and depth coaching for an untrained rescuer |
| Gym or fitness facility | ZOLL AED 3 | Free pediatric coverage, CPR Dashboard, IP55. See our gym guide |
| School | ZOLL AED 3 or LIFEPAK CR2 | Both include pediatric. CR2 wins if trained staff respond, AED 3 wins on cost |
| Corporate fleet with a program manager | LIFEPAK CR2 | Wi-Fi readiness reporting and 8-year warranty reduce admin burden across many units |
| Trained medical or security responders | LIFEPAK CR2 | cprINSIGHT pays off most when the operator is competent enough to exploit the shorter pause |
| Lowest possible total cost | ZOLL AED Plus, recertified | $875 plus $330 per decade beats every alternative here |
