AED Pad & Battery Compatibility Chart

Every AED model we sell in Canada, with the exact pads and battery that fit it. Ordering the wrong pads is the most common mistake in this category — this page exists so it doesn't happen to you.

The five mistakes we see most often

• Philips FRx pads on an OnSite. Both are "Philips HeartStart pads." Philips states plainly that FRx SMART Pads II are not for use with HS1, OnSite or Home units. This is the single most common wrong order in Canada.
• Uni-padz on an AED Plus. CPR-D-padz fit both the AED Plus and the AED 3. Uni-padz fit the AED 3 only. They look similar and both have a CPR sensor.
• Pedi-padz II on an older AED Plus. Your AED Plus must carry the pediatric-capable symbol. Units without it will not work with Pedi-padz II and need a ZOLL upgrade kit first.
• Defibtech "1xx" vs "2xxx" parts. DDP-100 and DDP-200P fit the original Lifeline. DDP-2001 and DDP-2002 fit the VIEW/ECG/PRO. They are not interchangeable.
• HeartSine Pad-Pak numbering. PAD-PAK-01, -03 and -07 are adult. PAD-PAK-02 and -04 are pediatric. The numbers don't run in order — trust the colour: grey is adult, pink is pediatric.

Common questions

How do I know when my pads expire?

Every pad package carries a printed expiry date, usually on the foil pouch and again on the outer box. Most AEDs will also chirp or show a service indicator once pads pass their date. Pads expire whether or not the device has ever been used — the gel dries out.

Can I use expired pads in an emergency?

Yes — using expired pads is better than doing nothing, because the alternative is no defibrillation at all. But expired gel conducts poorly and the shock may be less effective, so they should be replaced immediately afterwards. Expired pads are not a substitute for in-date ones.

Do I need separate pediatric pads?

It depends on the model. Philips FRx and LIFEPAK CR2 switch to pediatric energy with a key or a button and use the same pads. ZOLL, Defibtech, HeartSine and Cardiac Science all require physically different pediatric pads or cartridges. Check the chart above for yours.

My AED is discontinued. Can I still get parts?

Often yes. Call us at 1-877-851-0756 with the model and, if you can, the part number from the old pads. We can usually source consumables for older units, and if we genuinely can't, we'll tell you rather than sell you something that doesn't fit.

How do I stop this creeping up on me?

Ask us to put your units on expiry reminders. Send the model and purchase date and we'll email you ninety days before your pads or battery lapse, with a direct link to reorder the right part. It's free.

Still not sure? Call 1-877-851-0756 or email sales@shockshop.ca with your AED's make, model and — if you can find it — the part number printed on your current pads. We'd much rather spend two minutes confirming than have you order the wrong part for a life-safety device.

Manufacturers change specifications without notice. Where a part matters to a compliance decision, confirm against the manufacturer's own documentation or call us.
