How much do AED replacement pads cost?
M5071A adult SMART Pads for the Philips OnSite are $99 at AED Leader and Response Ready on 18 September 2026, against $169 at the Philips shop, $139 at American AED and $139 to $199 at the other ranking sellers. Pediatric M5072A is $139. Across brands, adult pads run $75.15 (Defibtech) to $234 (ZOLL CPR Uni-padz).
What is the expiration date for Philips AED pads?
Two years from the date of manufacture, printed on the cartridge. The OnSite reads the cartridge and flashes its status indicator when the pads are expired, but the printed date is the one to log.
How often do Philips AED pads need to be replaced?
Every two years unopened, and immediately after any use, even if no shock was delivered. The M5070A battery runs a separate four-year clock, so a typical OnSite needs two pad cartridges for every battery.
How to replace Philips HeartStart AED pads?
With the OnSite off, press the latch on the pads cartridge and pull it out, slide the new M5071A cartridge in until it clicks, then confirm the green Ready light. No tools, about a minute. Keep the old cartridge until the light confirms the new one.
Where can I find replacement pads for my Philips HeartStart defibrillator?
Authorized Philips distributors: AED Leader and Response Ready stock M5071A ($99) and M5072A ($139). For an FRx you need SMART Pads II (989803139261, $89), not this cartridge.
When to replace the cartridge
Replace after each patient use. Replace when the expiration date on the cartridge has passed. The OnSite AED will signal pad expiration through its status indicator light.
Shelf Life and Storage
Store in original packaging in a cool, dry location. The cartridge has a printed expiration date. Order replacements before this date to ensure continuous readiness.
Key Features
- SMART Pad technology senses rescuer actions to adjust device prompts
- Pre-connected cartridge design for tool-free installation
- Designed for adult patients on the HeartStart OnSite
- Clear pad placement guide included
M5071A are the adult replacement pads for the Philips HeartStart OnSite (HS1). The part number disambiguates from M5072A (pediatric), confusingly similar SKUs that account for the #2 wrong-purchase mistake in Philips refills. M5071A does NOT fit the FRx (which uses SMART Pads II).

Frequently asked questions.
M5071A vs M5072A: which one do I order?
M5071A is the adult pad for the OnSite (HS1). M5072A is the pediatric pad for the same OnSite (HS1). The part numbers differ by exactly one digit, which is a major source of wrong-purchase errors. Read the package carefully and confirm the patient population before ordering. Adult M5071A is correct for offices, home buyers, retail counters, and any adult-only site. Pediatric M5072A is required for schools, daycare, youth athletics, and any site serving children; schools should stock both.
Will M5071A fit my Philips FRx?
No. M5071A is OnSite-only. The Philips FRx uses SMART Pads II, which has a different connector and pad backing despite both being “Philips adult HeartStart” branded. Forcing wrong-SKU pads into either device will cause connection failures. The FRx workflow is SMART Pads II + Child Key for pediatric; the OnSite workflow is M5071A adult + M5072A pediatric. Different SKU strategies, different devices. Always confirm the model number on your device before ordering refills.
What does the part number actually mean?
The “M” prefix is Philips’ HeartStart product line code. “5071” identifies the adult OnSite pad SKU. “A” is the revision letter (currently A; future revs will be M5071B, etc.). M5072A means the pediatric variant of the same OnSite pad line. The pattern matters because Philips also has M5070A (battery), M5066A (full OnSite device), and M5068A (the HeartStart Home device) and 861304 (the FRx), all sharing the M507x naming convention. Misreading part numbers by one digit is the most common Philips order mistake.
