AED Battery and Pad Replacement: When, How and Costs

Ensuring your AED is ready when every second counts means knowing when to swap out batteries and pads, how to do it correctly, and what budget to set aside. This comprehensive guide provides clear instructions, cost insights, and handy record-keeping tips to help keep your community safe.

Why Regular Checks Matter

Stat Callout: Regular AED inspections are linked to improved device readiness. According to an analysis of FDA-reported AED failures, around 45% of malfunctions occurred during charging or shock delivery attempts, failures often tied to poor maintenance. While exact percentages vary, quarterly inspections remain a recommended best practice by organisations like the Red Cross and Resuscitation Council UK.

Why it matters: expired batteries or worn pads can cause an AED to underperform during a cardiac emergency, risking precious seconds and potentially voiding warranties. Regular checks help you stay compliant with health and safety standards and ensure your device works when needed.

Fun fact: Our pads & batteries page attracts nearly 500 visits every six months, proof that people seek reliable, actionable advice.

When to Replace Your Batteries & Pads

  • Battery lifespan: Typically 2 to 4 years, depending on the AED model and usage.
  • Pad lifespan: About 18 to 30 months; always replace after use or if expired.

Pro Tip: A quarterly inspection routine helps you catch expiries and readiness issues before they become emergencies.

Step-by-Step: Changing Your AED Battery

  1. Power Down & Open: Turn off the unit and open the battery compartment.
  2. Remove Old Module: Gently slide out the expired battery pack.
  3. Insert New Module: Align contacts and insert until you hear a click.
  4. Run Self-Test: Power on and confirm the green light or “OK” status.
  5. Log & Recycle: Note the date and batch number, then recycle the old battery responsibly.

Step-by-Step: Swapping Out AED Pads

  1. Access the Pads: Release the latch to open the pad compartment.
  2. Attach Fresh Pads: Peel foil backing and secure the new electrodes.
  3. Route Cables Carefully: Ensure wires aren’t pinched when closing the compartment.
  4. Confirm with Self-Test: Run the pad-check function to verify integrity.
  5. Record & Seal: Check expiry dates, log the swap, and reseal the compartment.
