AED Pad Replacement Cost by Brand: 2026 Price Sheet

Most AED owners discover the pad-replacement bill the same way: a daily self-test alert turns red two years after install, and the procurement manager learns that the “single set” of pads is brand-locked, FDA-regulated, and costs anywhere from $75 to $282 depending on the model. Multiply that across a fleet of 8 AEDs in a school district, every 2 years, for the device’s 8 to 10 year lifetime, and pad replacement quickly becomes the largest line item in the AED program, bigger than the device itself.

This is the complete 2026 price sheet for replacement pads across every major brand sold in the United States. Use it to budget your AED program, validate quotes from resellers, and calculate true cost of ownership before purchase decisions. Pricing reflects AED Leader retail pricing checked in September 2026; verify with the seller before purchase.

Why pad prices vary so much between brands

A bare-bones adult pad pair from Defibtech runs about $75.15. A ZOLL CPR-D feedback pad runs about $230. The 3× price gap isn’t manufacturer markup, it reflects four engineering and regulatory variables:

1. Embedded sensors. ZOLL CPR-D and Powerheart G5 ICPR pads include CPR feedback sensors inside the pad; LIFEPAK Quik-Step pads use standard electrodes, and the CR2 measures CPR through the pads’ impedance instead. Each sensor adds material cost.
2. Shelf life. Pads rated for 5 years (ZOLL) use higher-grade conductive gel and sealed packaging than 2-year pads (Philips, Defibtech, Cardiac Science). Longer shelf life = higher per-unit manufacturing cost.
3. FDA Class III regulation. AED pads are classified by the FDA as Class III medical devices, requiring premarket approval and ongoing quality-system audits. Compliance cost is built into every set sold.
4. Brand-locked compatibility. Pads are not interchangeable across brands. Each manufacturer maintains a captive supply chain. Limited competition keeps prices structurally elevated.

The 2026 brand-by-brand pad price sheet

Most pad prices in this table are AED Leader list prices checked in September 2026. Volume discounts (10+ units) typically reduce the per-set cost by 8 to 15%. Confirm current pricing with AED Leader or directly with manufacturer-authorized resellers.

Cost-per-year of coverage: the metric that actually matters

Sticker price is misleading. A ZOLL CPR-D pad set at $230 covers 5 years; a Defibtech pad set at $75.15 covers 2 years. Normalize both to annual cost, and ZOLL becomes only about $8 a year dearer than Defibtech (about $46 against about $38 a year) , while delivering CPR feedback sensors.

This is the single most important number when budgeting AED replacement pads. Map it across an 8-year device lifecycle to project the true pad expense.

8-year pad replacement projection (per device)

If you are pricing a fleet, multiply these figures by the number of deployed devices. A school district with 12 AEDs running on LIFEPAK CR2 will spend roughly $4,700 in pads over 8 years; the same fleet on Defibtech runs about $3,600. The decision starts to look very different when you see the 8-year picture.

The HeartSine PAD-PAK exception

HeartSine combines pads and battery into one sealed cartridge, the PAD-PAK. You replace both consumables in a single transaction every 4 years. This is unique among major brands and worth modeling separately:

• One purchase order instead of two
• One expiration date to track
• One installation step (snap the cartridge in)
• One SKU to keep in inventory

For organizations without dedicated facilities maintenance staff , single-site small businesses, churches, daycare facilities, this maintenance simplification can outweigh a marginally higher per-cycle cost.

Pediatric pad cost premium

Pediatric pads cost about 30 to 60% more than adult pads on most brands. Three reasons:

1. Smaller production volumes (most AED deployments are adult-primary)
2. Energy-attenuation circuitry is built into the pad cable on some models
3. Stricter pediatric FDA classification documentation

The exception: the Philips HeartStart FRx Infant/Child Key. Instead of a second pad set, you buy a single key (about $139) that attenuates shock energy when inserted into the AED, it works with the adult pads already in the unit. For multi-room facilities with kids and adults, this design dramatically lowers pediatric-readiness cost.

Counterfeit pads: an emerging risk

The FDA’s Safety Communications have flagged a rising number of counterfeit AED pads sold through online marketplaces. Counterfeit pads can fail to deliver therapy or cause skin burns. Three rules to stay safe:

Bulk & multi-unit discounts

Resellers typically offer tiered pricing on multi-pack orders:

For organizations managing 10+ AEDs, consolidate pad replacements to a single annual purchase to capture maximum discount and synchronize expiration tracking.
