Buying an AED is one decision. Keeping it ready to save a life is a five-to-seven year maintenance cycle: pads expire, batteries die on the wall, cases crack, cabinets get pulled off mounts. The AED accessories in this collection cover the full ownership lifecycle — replacement electrode pads (adult and pediatric), batteries, cabinets, carrying cases, and brand-specific keys for ZOLL, Philips, Cardiac Science, and Defibtech defibrillators. Whether you're maintaining one unit at home or fifty across a multi-site program, this is where you replace what's worn out before it costs someone a survival window.

What Counts as an AED Accessory?

An AED accessory is anything you'll need to replace, mount, or carry — but isn't the AED itself. Five main categories cycle through during ownership:

• Replacement electrode pads (adult and pediatric)
• Batteries (4–7 year lifespan depending on brand)
• Wall cabinets (with or without alarms, indoor or outdoor)
• Carrying cases (soft or hard, brand-specific or universal)
• Brand-specific keys (Philips FRx infant/child key, for example)

Knowing which category you need narrows the buying decision quickly.

Replacement Pads — Why They Expire and What to Buy

Live electrode pads aren't reusable. They carry conductive gel that dries out, adhesive that loses tack, and lot-tracked expiration dates that range from two to five years depending on the manufacturer. Once expired, they may fail to deliver therapy correctly during an emergency — which is the worst possible time to discover the problem.

We stock replacement pads for every major brand:

• ZOLL — Stat Padz II, CPR-D-padz, Pedi-padz, AED 3 CPR Uni-padz
• Philips — HeartStart OnSite adult and pediatric, FRx replacement pads
• Cardiac Science — Powerheart G3 and G5 adult and pediatric electrodes
• Defibtech — Lifeline adult and pediatric, VIEW/ECG/PRO compatible pads

See the full AED replacement pads collection for every model we carry.

Replacement Batteries — Lifespan and Compatibility

Battery life is the silent killer of public-access AEDs. Devices left on the wall run daily self-tests, drawing a slow but constant current; most batteries last 4 to 7 years before they trigger a low-battery warning. Heavy stand-by drain in cold or hot environments shortens that further.

Batteries we stock include:

• Philips OnSite/FRx (M5070A) and generic compatibles
• ZOLL AED Plus lithium (8000-0807-01) and AED 3
• Cardiac Science Powerheart G3 compatible
• Defibtech Lifeline 5-year (DCF-200) and 7-year (DCF-210)

Cabinets and Wall Mounts

A cabinet protects the AED from dust, tampering, and accidental knocks while keeping it visible enough that bystanders can grab it without searching. Cabinet specs vary by environment:

• Indoor with alarm — deters tampering in lobbies, gyms, and reception areas
• Indoor with strobe — improves visibility in low-light corridors and stairwells
• Outdoor weather-rated — for stadium concourses, parks, and parking garages
• Large-kit cabinets — fit AED, spare pads, battery, and first-aid pack together

See the AED cabinets collection for full specs and mounting hardware.

Carrying Cases for Mobile AED Programs

If your AED moves with you — first-responder vehicles, athletic team kits, traveling medical providers — the case it lives in determines how long it survives. Hard cases (like the Philips Pelican Case) take impact. Soft cases (ZOLL Soft Carry Case, Philips OnSite/FRx replacement carrying cases) are lighter for in-and-out daily use. Browse AED cases for impact-rated and lightweight options.

Brand-Matched Accessories We Stock

Different AEDs need different accessory ecosystems. We carry matching consumables for every brand we sell:

• ZOLL — pads, batteries, soft cases, training electrodes
• Philips — adult and pediatric pads, M5070A batteries, FRx infant/child key, hard and soft cases
• Cardiac Science — Powerheart G3 and G5 pads, batteries, training units
• Defibtech Lifeline — adult and pediatric pads (DDP-100, DDP-200P, DDP-2001), 5-year and 7-year batteries

If your AED isn't listed, send us the model number — most defibrillator accessories are still manufactured even for older units.

Building an AED Maintenance Calendar

A working maintenance rhythm avoids the "dead unit on the wall" surprise. Use this as a starting template:

Programs running 5+ AEDs across multiple sites should consider a maintenance service plan. Contact us for bulk pricing or service contract options.

Frequently Asked Questions

How often do AED pads need to be replaced?

Adult electrode pads typically expire 2 to 5 years from the manufacturing date, depending on brand. Pediatric pads have similar shelf lives. Check the printed expiration on the pad packaging — not the date you bought them — and replace before that date passes.

Are generic AED batteries safe to use?

Generic batteries are safe and effective when sourced from a reputable supplier and listed as compatible with your specific model. The cost savings are real (sometimes 30 to 50 percent off OEM). We carry both OEM and tested compatibles — both pass full self-test cycles on the live unit.

Do AEDs need replacement pads even if they've never been used?

Yes. Pads carry conductive gel that dries out and adhesive that loses tack regardless of use. Replace by the printed expiration date. The same applies to batteries — a never-used battery will still hit end-of-life on the calendar.

What's the difference between adult and pediatric AED pads?

Pediatric pads deliver a reduced shock dose calibrated for patients under 8 years old or under 55 lbs. Some brands use separate pediatric pad sets; others (like Philips FRx) use a child key inserted into the device alongside adult pads. Always have pediatric coverage where children are present — schools, gyms, family venues.

How do I know which AED accessories fit my unit?

Check the model number on the back of your AED. Each manufacturer's pads and batteries are model-specific — for example, ZOLL Stat Padz II fit the AED Plus but not the AED 3. If you're unsure, send us a photo of your device label and we'll confirm the match.

Do you carry AED accessories for older or discontinued units?

Often, yes. Many AED accessories remain manufactured even after the parent device is discontinued — Cardiac Science Powerheart G3 batteries and pads, for example, are still available. Send us your model number and we'll confirm availability before you need it.
