AED Replacement Pads by Brand and Model
AED pads are one of the most important replacement supplies in an AED program. The AED may be mounted in the right place, the cabinet may be visible, and the battery may still show ready, but expired or incompatible pads can still create a readiness problem for the AED unit.
This guide helps buyers choose AED pad replacements by brand and model, understand adult vs. pediatric pads, and know when to order AED replacement batteries and pads together.
Need AED pads for your device?
AED USA carries AED pads for major AED brands, including ZOLL, Philips, Defibtech, HeartSine, Physio-Control/Stryker, and Cardiac Science.

What are AED electrode pads?
AED pads are adhesive electrode pads, or adhesive pads, that connect the automated external defibrillator to the patient. They are placed on the patient’s chest so the AED can analyze heart rhythm and, when appropriate, deliver a shock. Pads are single-use and model-specific, meaning the right replacement pads depend on the AED brand and device model they are designed for.
Most AED programs need to track at least one set of adult pads. Many programs also need pediatric pads if children may be present. Some AEDs use separate adult and pediatric pads, while others use model-specific pad systems or keys/accessories for pediatric use.
AED replacement pads are not universal
The most common buying mistake is assuming that all AED pads work with all AEDs. They do not. AED pad replacements must match the AED brand and model of the AED machine.
Before ordering, confirm:
- AED brand;
- AED model;
- adult or pediatric use;
- pad expiration dates;
- whether the pads were opened or used;
- whether the AED also needs a battery;
- how many AED locations need replacement supplies.
If the device is a Philips HeartStart OnSite, it needs pads made for that model. If it is a ZOLL AED Plus, it needs compatible ZOLL AED Plus pads. If it is a HeartSine samaritan device, it may use a Pad-Pak cartridge style. Matching by brand alone is not enough, and matching the correct pads helps ensure the device is ready when needed.

When should AED pads be replaced?
AED pads should be replaced to maintain readiness for sudden cardiac arrest and SCA response when they expire, after they are used, if the package is opened or damaged, if the adhesive has been compromised, or if an inspection shows the pads are missing.
Replace AED pads if:
- the expiration date has passed;
- the pad package is torn, punctured, or no longer sealed;
- pads were attached to a patient;
- pads were opened during training or inspection;
- the AED status indicator shows an accessory issue;
- pads are missing from the case or cabinet;
- pads may no longer stick properly;
- pads are not compatible with the AED model;
- adult pads are present but pediatric pads are required for the location.
AED pads for sale should always be evaluated by compatibility and expiration needs, which are critical, not just price.
Adult AED pads vs. pediatric AED pads
Adult AED pads are intended for adult patients and are the default pads stored with most public-access AEDs. Pediatric AED pads are intended for children and should be considered anywhere children may be present, including schools, childcare settings, churches, community centers, sports facilities, dental offices, family entertainment venues, and public buildings.
Adult AED pads
Adult pads are normally the primary pad set in the AED case. They should be sealed, current, and attached or stored according to the AED manufacturer’s instructions.
Pediatric AED pads (pediatric pads)
Pediatric pads reduce or adapt therapy for children according to the AED system design. The exact age/weight guidance depends on the AED model and current manufacturer instructions, and some systems use a pediatric key instead of separate pediatric pads. If your facility serves children, do not wait until an emergency to learn whether pediatric pads are available.
AED pads by brand
Use the AED unit brand and model to choose replacement pads. AED USA organizes AED replacement pads and batteries by brand so buyers can narrow the selection quickly. Some programs also buy aed trainers by brand and keep them separate from live-response supplies.
ZOLL AED pads
ZOLL AED pads include options for ZOLL AED Plus and ZOLL AED 3 devices. Common ZOLL replacement pad paths include CPR-D-padz, Stat-padz, Pedi-padz, and ZOLL AED 3 pad options depending on the device model.

Not sure which pads fit your AED?
Use the AED brand and model name, then shop by brand. AED USA can help match pads, batteries, and accessories for your AED program.
Should you order AED replacement batteries and pads together?
Sometimes. AED pads and batteries have different replacement schedules, but maintenance should include regularly checking both together. If pads are expired, the battery may still be good. If the battery is due, pads may still be current. The best approach is to inspect both and replace what is expired, depleted, used, missing, or near end of life.
Order AED replacement batteries and pads together when:
- both are expired or near replacement date;
- inspection records are missing;
- the AED came from another location or previous owner;
- you are refreshing a multi-location AED program;
- shipping together reduces administrative work.
Do not delay replacing expired AED pads just because the battery still looks ready. Pads are a separate readiness item, and keeping both current is essential for readiness.
How to build an AED pad replacements schedule
A simple AED pad replacement schedule can help ensure supplies are on hand before they are needed. For each AED, record:
- AED brand and model;
- battery expiration or installation date;
- next inspection date;
- person responsible for the AED.
Review this information at least monthly and after any use, keeping replacement pads on hand across multiple locations. For multi-location organizations, centralize the records so one site does not fall behind while another stays current.
AED pads for businesses, schools, gyms, churches, and public facilities
Different sites support different individuals, so they may need different AED pad setups. A small office may need one set of adult pads and a clear replacement schedule. A school may need adult and pediatric pads across multiple AEDs, and students and staff may benefit from hands-on preparedness support alongside the device setup. A gym or sports facility may need highly visible pads, batteries, cabinets, signage, and staff training support.
Common AED pad buyers include:
- offices and corporate facilities;
- schools and universities;
- churches and houses of worship;
- gyms and fitness centers;
- dental and medical offices;
- warehouses and industrial sites;
- municipalities and public buildings;
- hospitality and event venues;
- property managers and multi-site operators.
AED USA can support single-device replacement orders as well as broader AED program refreshes.
How to inspect AED pads
During routine AED inspection, check:
- Are pads present?
- Are pads sealed?
- Are pads current and not expired?
- Are pads compatible with the AED model?
- Are pediatric pads present if needed?
- Is the pad cable connected if the model stores pads preconnected?
- Is the AED status indicator showing ready?
- Is the AED cabinet visible and accessible?
- Are signage and response supplies still present?
Inspection is a key part of AED readiness and should help ensure the pads are sealed, current, and ready for treatment.
If any answer is uncertain, document the issue and order the correct replacement supply.
How long do AED pads last?
AED pad shelf life depends on the pad model and manufacturer. Always check the expiration date printed on the package and replace pads before or at expiration according to your AED program policies.
Can AED pads be reused?
No. AED pads are single-use. Replace pads after they have been applied to a patient, and do not reuse them, or if they are opened in a way that compromises the sealed package.
Are AED pads universal?
No. AED replacement pads are brand- and model-specific. Always match pads to the AED model before ordering.
Do I need pediatric AED pads?
If children may be present at your location, pediatric readiness should be reviewed. Pediatric pads or settings are designed to provide adjusted treatment for children based on the AED model. The correct pediatric pad or pediatric setting depends on the AED model and current manufacturer instructions.
Where can I buy AED pads?
AED USA sells AED pads for major brands at https://www.aedusa.com/aed-pads-and-batteries, with brand-specific categories for ZOLL, Philips, Defibtech, HeartSine, Physio-Control, and Cardiac Science. If you have questions about brand, model, or compatibility, shop by category or contact AED USA for help.
Should I replace the AED battery when I replace pads?
Check the battery every time you check pads to ensure the AED is ready for cardiac arrest response. Replace the battery if it is expired, depleted, used according to device guidance, missing, or flagged by the AED self-test, especially since pads and batteries do not always expire at the same time.
