The battery detail nobody explains
Quick answer
Almost every other AED locks you into a single-source battery: Philips M5070A at about $249 every 4 years, Powerheart G5 XBTAED001A at about $495 every 4 years. ZOLL instead built the AED Plus around commodity lithium cells, so a full set runs about $100 and lasts roughly 5 years in standby.
Two practical notes. Buy a matched set and replace all ten at once rather than mixing old and new cells, because the device draws from them as a bank. And buy from a source that dates the cells, since lithium 123A shelf life is long but not infinite. If you would rather not think about it, ZOLL sells a branded battery kit and that is the safe default.

Why one-piece pads matter more than the price
Quick answer
This is the same logic that makes HeartSine’s Pad-Pak attractive, applied differently. The AED Plus asks you to track two dates (pads and battery) instead of the three or four an owner ends up juggling elsewhere, and the CPR sensor that powers Real CPR Help lives inside the pad rather than as a separate accessory.
One correction worth making, because it is repeated constantly: Real CPR Help is on both the AED Plus and the ZOLL AED 3. The AED 3’s actual differentiator is its color CPR Dashboard display, not the presence of compression feedback. We cover that properly in the AED 3 vs AED Plus comparison.
The honest cost of this design: FDA data shows roughly 46.9% of reported AED failures involve batteries or pads (DeLuca et al., Annals of Emergency Medicine, 2012, 40,787 reported events). A one-piece pad reduces the number of things that can quietly expire, but it does not remove the need to track the ones that remain.
The pediatric line item
Quick answer
This is the AED Plus’s weakest point and it is worth stating plainly, because it is the line item that flips a purchase decision for schools, gyms, and families. Five replacement cycles at $155 is $775 of pediatric spend across a decade on a device whose adult consumables only cost $330. Our schools guide works this through at institutional scale, and the ZOLL AED 3 review covers the alternative.
If pediatric use is occasional rather than expected, note that the AHA permits adult pads on a child when pediatric pads are unavailable: one pad on the chest, one on the back. Planned coverage is better. No coverage is still far better than no defibrillation.

Fleet math: the cheapest AED to run at scale
Quick answer
| Fleet size | ZOLL AED Plus | Philips OnSite | Powerheart G5 |
|---|---|---|---|
| 1 unit | $330 | $894 | $1,342 |
| 5 units | $1,650 | $4,470 | $6,710 |
| 10 units | $3,300 | $8,940 | $13,420 |
| 25 units | $8,250 | $22,350 | $33,550 |
Recertified units: when your clock starts
Quick answer
That figure is the cheapest ten covered years available from any device we track, and it exists because two things stack: the recertified discount and the commodity battery design. Verify before buying that new pads and battery are included, that the warranty is written down, and that the reconditioner documents serial history so the unit can be checked against FDA recall listings.
Details in how to choose a refurbished AED, the recertified AED pillar, the recertified ZOLL AED Plus page, and the refurbished vs new analysis. Cross-brand comparisons live in the ZOLL vs Philips OnSite page, the recertified AED 3 breakdown, and the 2026 rankings.
Buying the device itself
If you are pricing consumables before deciding what to buy, the numbers above are the strongest argument for the AED Plus and the reason it appears in nearly every ranking we publish. New units run about $2,082, and recertified units are $875 with a 3-year warranty, which makes a recertified AED Plus plus a decade of consumables roughly $1,205 all-in. That is the cheapest ten covered years available, and we show the full ladder in the best AED for home guide and the refurbished buying guide.
Full device analysis lives in the ZOLL AED Plus review, and the cross-brand consumables table sits on the AED pads and batteries pillar. Philips owners should read the Philips HeartStart parts guide instead.
