Buying a Used Defibrillator: The 9-Point Checklist Before You Purchase

Defibrillators hold their value for good reason: they are engineered to work the one time everything depends on it. Buying used is completely legitimate — hospitals do it every day — but this is not a category for casual purchasing. Here is the checklist we use ourselves.

The 9-point checklist

  1. Self-test pass, documented. Every modern defibrillator runs automatic self-tests. Ask for a photo or log showing a current pass — not “it worked last year.”
  2. Battery age and cycle count. Batteries are consumables. Budget for a fresh battery on any used unit, and confirm replacements are still manufactured for that model.
  3. Pads/electrodes in date. Expired pads are the most common failure found in AED inspections.
  4. Energy delivery verified. A proper reseller tests actual joule output against specification with an analyzer — ask for the test result.
  5. Recall check. Look the model up in the FDA recall database before you commit. A reputable seller has already done this.
  6. Software/firmware current. Some older units require updates to match current AHA guidelines.
  7. Accessories and cables. Therapy cables, ECG leads, and chargers are pricey to source separately.
  8. FDA device tracking. Defibrillators are federally tracked devices (21 CFR Part 821). A legitimate seller records the serial number and purchaser — if they don’t ask who you are, that’s a red flag about everything else.
  9. Your state’s AED rules. Many states require a prescribing physician or medical direction, EMS registration, or maintenance programs for AED deployment. Check before it ships.

AED vs. manual defibrillator

AEDs (like the Philips HeartStart OnSite) are designed for lay responders and most workplaces. Manual/monitor defibrillators (Lifepak, Philips M-series) belong in clinical settings with trained staff — they are prescription devices sold only to licensed providers.

Every defibrillator we sell is function-tested, recall-checked, and serial-tracked at checkout. See current units in the Provider Portal.
