AED Maintenance Best Practices

An AED is only effective if it's ready when needed. Proper maintenance ensures your device will function perfectly during a life-or-death emergency.

Daily Automated Self-Tests

Modern AEDs perform automatic self-diagnostic tests daily:

What's Tested

  • Battery charge level
  • Internal circuitry
  • Software integrity

  • No physical damage to case
  • Cabinet alarm functioning (if applicable)
  • All accessories present
  • Signage visible and intact

    • Documentation

  • Record inspection date
  • Note any issues
  • Sign inspection log
  • Report problems immediately

    • Monthly Detailed Checks

    Device Inspection

  • Verify battery expiration date
  • Check pad expiration date
  • Inspect pad package for damage
  • Test status indicator
  • Review event log (if accessible)

    • Battery Management

    Battery Life

  • Lithium batteries: 4-5 years standby
  • Rechargeable batteries: 2-3 years
  • After use: May need immediate replacement

    • Replacement Indicators

  • Expiration date approaching
  • Status indicator shows low battery
  • After certain number of shocks
  • Following manufacturer schedule

    • Best Practices

  • Stock spare batteries
  • Track expiration dates
  • Replace before expiration
  • Use only manufacturer-approved batteries
  • Properly dispose of old batteries

    • Electrode Pad Care

    Pad Lifespan

  • Typically 2 years unopened
  • Single-use only
  • Gel can dry out over time
  • Environment affects longevity

    • Replacement Schedule

  • Before expiration date
  • After any use
  • If package damaged
  • If gel appears dry

    • Storage Tips

  • Keep pads in sealed package
  • Store at room temperature
  • Avoid extreme temperatures
  • Don't expose to direct sunlight
  • Check package integrity monthly

    • After Each Use

    Immediate Actions

    1. **Replace electrodes**: Install new pads immediately

    2. **Check battery**: May need replacement

    3. **Clean device**: Wipe down exterior

    4. **Inspect for damage**: Check for cracks or issues

    5. **Test functionality**: Verify status indicator

    Data Management
