AEDs should undergo regular service by experienced technicians based on the following guidelines:
- Routine checks: Conducted monthly or quarterly to ensure the device is functioning properly.
- Preventive maintenance: Typically done once a year, or as recommended by the manufacturer.
- Battery replacement: Batteries should be replaced every 3–5 years, depending on usage and manufacturer specifications.
Electrode pad replacement: Pads usually need replacing every 2 years, or when they have expired, whichever comes first.
