This comprehensive guide covers everything you need to know about selecting, maintaining, and replacing AED pads and batteries so your automated external defibrillator is ready the moment it matters most.

Answering Your Most Important AED Pad & Battery Questions First

AED batteries and pads are the two critical consumables that answer the most important AED readiness question: will your device work during sudden cardiac arrest. Pads are single-use adhesive electrodes that read heart rhythm and deliver a controlled shock when advised, while batteries power daily self-diagnostics, voice prompts, and shock delivery during a rescue. For facility safety managers, health and safety officers in schools, businesses, churches, and rural community centers—as well as homeowners keeping an AED ready—proper selection, inspection, and replacement of these factory-sealed components is what prevents avoidable device failure.

If either component is expired, damaged, or incompatible, the device may fail to deliver a life-saving shock, which makes replacement timing critical to AED readiness. Below, you’ll find clear guidance on choosing compatible OEM supplies, understanding adult and pediatric pad options, checking battery type and lifespan, following maintenance and inspection schedules, and knowing where to buy replacement AED batteries and pads from AEDLand.

• What are AED pads? Single use adhesive electrode pads that read the heart rhythm and deliver a controlled shock when the device advises it.
• What are AED batteries? The primary power source that supports daily self-diagnostics, voice prompts, and shock delivery during a rescue.

When do I replace AED pads?

• When the expiration date on the foil pouch has been reached; AED pad shelf life is typically 2 to 5 years
• After every use, even if no shock was delivered – pads are single use and cannot be reused
• If the pouch has been opened, torn, or shows moisture damage
• If the adhesive looks dried out or fails to stick during inspection

When do I replace an AED battery?

• At or before the printed expiration date
• When the AED chirps, fails a self-test, or shows a low battery indicator
• After a rescue involving multiple shocks or prolonged monitoring, if the manufacturer recommends it
• When visual inspection reveals corrosion, swelling, or a depleted status light

AED pads and batteries are not universal. They must match the exact AED brand and model. For example, a ZOLL AED Plus requires completely different pads than a ZOLL AED 3, and Cardiac Science Powerheart G3 pads will not fit a G5.

What Are AED Pads and Electrode Pads and How Do They Work?

AED pads – also called electrode pads or pad cartridges – are single use medical devices designed to connect the AED, one of the portable automated external defibrillators used in cardiac emergencies, to the patient’s skin. Choosing the right AED parts is crucial for device reliability and compliance.

• One pad is placed on the upper right chest (below the collarbone) and the other on the lower left rib cage for adult patients
• The AED uses the pads to analyze the heart rhythm via ECG signals
• If a shockable rhythm is detected, the device delivers a controlled shock through the same pads
• Some AEDs integrate battery and pads into a single cartridge with one expiration date, like the HeartSine Pad-Pak

Every manufacturer designs pads specifically for their systems. ZOLL AED Plus CPR-D-padz include integrated CPR feedback that coaches rescuers on compression depth, while Cardiac Science and Philips use their own proprietary connector and gel formulations.

Pads contain conductive gel that can degrade over time, affecting adhesion and electrical contact. That is why every set carries an expiration date printed on the sealed pouch – often 2 to 4 years from manufacture. Most pads are latex-free and include placement diagrams directly on the pad surface so that even untrained individuals can apply them quickly in an emergency.

AEDLand only sells genuine OEM and FDA-cleared replacement pads for major brands – not third-party knockoffs.

Adult vs. Pediatric AED Pads (Including Pediatric AED Pads Options)

The difference between adult pads and pediatric AED pads matters because energy levels and pad placement differ for children. Using the wrong set can result in an ineffective or potentially harmful shock.

• Adult pads: Intended for patients 8 years old and older or weighing over 55 lbs (25 kg). These are the standard selection for workplaces, gyms, churches, and public buildings.
• Pediatric pads: Designed to attenuate shock energy for children under 8 years old or under 55 lbs. They adjust the device’s algorithm and delivered energy to levels safe for smaller bodies.

Organizations that should strongly consider stocking pediatric pads alongside adult pads include elementary and middle schools, childcare centers, churches, community centers, youth sports facilities, and family restaurants.

Some AEDs use separate pediatric pads – like the ZOLL Pedi-padz II or Cardiac Science pediatric pads. Others, such as the Philips HeartStart FRx, use an Infant/Child Key that tells the device to reduce energy without requiring a separate pad set.

Document the age and weight criteria for your specific AED model in your emergency response plan so staff know when to choose pediatric vs. adult pads. On AEDLand, product pages clearly label each option and include age, weight ranges, and expiration dates.

AED Pads by Brand and Model (Including Zoll AED Compatibility)

AED pads must match the AED brand and model. Using unapproved pads or batteries can lead to AED failure in emergencies – the device may refuse to analyze, or worse, fail to deliver a shock.

ZOLL AED Pads

• ZOLL AED Plus uses CPR-D-padz (one-piece adult pads with real-time CPR feedback) or Stat-padz II
• ZOLL AED 3 requires CPR Uni-padz III – a universal pad set for both adults and children
• Always verify the exact ZOLL model listed on your device before ordering

Cardiac Science AED Pads

• Powerheart G3 uses adult pads 9131-001, while the G3 Pro requires pads 9660-001 – these are not interchangeable
• Powerheart G5 adult pads have their own part numbers (XELAED001B or XELAED002A)
• Each model family has specific adult and pediatric pads with shelf life typically between 2 and 4 years

Physio-Control / Stryker AED Pads

• LIFEPAK CR Plus, LIFEPAK Express, and LIFEPAK CR2 each require distinct pad sets
• Organizations with multiple LIFEPAK models should track which replacement pads apply to which device to avoid mix-ups

Other Brands at AEDLand

• Philips HeartStart (OnSite, FRx) with distinct adult and pediatric options
• Defibtech Lifeline models with separate adult and pediatric electrode pads
• HeartSine samaritan AEDs using combined Pad-Pak and Pedi-Pak cartridges

On AEDLand, you can shop by brand and model filters so only compatible supplies appear, reducing ordering mistakes.

AED Batteries: Types, Lifespan, and When to Replace Them

The AED battery powers everything from daily self-tests to voice prompts and shock delivery. An expired or depleted battery can render even brand-new pads useless – a failed AED component can prevent it from delivering a life-saving shock.

AED batteries are either non-rechargeable or rechargeable, and the battery type affects AED operational capabilities and maintenance:

Type	Common Use	Typical Lifespan
Non-rechargeable (lithium)	Public-access AEDs (ZOLL, Cardiac Science, Philips, Physio-Control)	3–5 years standby
Rechargeable	Professional/EMS environments with frequent training use	2–3 years before replacement

AED batteries typically last 2 to 5 years depending on the model. For instance, the Philips M5070A battery offers a 5-year shelf life before installation and 4 years of standby life once installed. Many Cardiac Science Powerheart models have 4-year replacement intervals under normal standby conditions.

Replace your AED replacement battery when:

• The printed expiration date is reached or within 6 months of expiring
• The status indicator shows a fault or the device chirps a warning
• After an event involving multiple shocks, if the manufacturer recommends it
• AED batteries should be replaced if expired or depleted – check batteries during routine inspections for readiness

Like pads, AED batteries are model-specific OEM parts. Pair a new battery purchase with at least one spare set of adult pads – and pediatric pads if needed – so your AED can support a full rescue and remain in service afterward.

Maintenance Schedules, Inspections, and Buying from AEDLand

How to Build Your AED Replacement Schedule

Regular inspections of AEDs ensure optimal functionality during emergencies. Many AED program requirements – including OSHA guidelines and state public access defibrillation laws – mandate documented maintenance. Maintaining an automated external defibrillator is vital for AED readiness.

Build your replacement schedules in four steps:

1. Create a log for each AED recording brand, model, serial number, location, pad expiration date, and battery expiration date
2. Check the status indicator and inspect the pad pouch monthly – routine checks should verify status indicator lights and expiration dates
3. Update the log after any AED use, replacing used pads immediately and evaluating the battery per manufacturer guidance
4. Create a structured maintenance schedule and set calendar reminders 90, 60, and 30 days before each expiration

Documenting the right place for each AED should also be part of the maintenance plan so staff can access it quickly during an emergency.

How to Inspect AED Pads and Batteries

During a quick pad inspection, verify:

• The expiration date is legible and in the future
• Packaging is intact without tears, punctures, or moisture damage
• Adhesive gel is not visible outside the sealed pouch – inspect AED pads for wear or damage regularly

AEDs perform automatic self-diagnostics to monitor functionality, but these electronic checks do not replace human visual inspections. AED maintenance includes regular visual inspections by staff. Charity-based recommendations suggest inspecting AED components frequently, and trained personnel enhance AED maintenance effectiveness. Maintaining a backup set of pads and a battery is a recommended safety practice that ensures your device is ready to save lives after any use or training session.

Multi-site organizations – schools, churches with multiple buildings, corporate campuses, rural districts – should centralize AED tracking into a single spreadsheet so no device is overlooked.
