How Often Do AED Pads and Batteries Need to Be Replaced?
AED pads and batteries do not last forever. Even if an AED has never been used, its electrode pads and battery have manufacturer-defined replacement requirements. The exact interval depends on the AED model and the specific consumable.
That means there is no universal rule such as 'replace every two years.' The correct approach is to follow the dates and instructions for your exact AED, pads and battery.
Why do AED pads expire?
AED electrode pads contain conductive adhesive gel that helps transfer energy and allows the device to analyze the heart rhythm. Over time, the pad materials can degrade or dry out. Pads should therefore be replaced by the manufacturer's expiry date and after they have been opened or used.
How long does an AED battery last?
Battery life also varies. Manufacturers may specify standby life based on defined conditions, and actual performance can be affected by self-tests, temperature, usage and other factors. The AED's status indicator and manufacturer instructions should always be followed.
ZOLL AED 3
The ZOLL AED 3 is notable for its long-life consumable design, with compatible pads and battery intended to support an extended replacement cycle under specified standby conditions. For organizations managing many locations, fewer scheduled replacement events can simplify lifecycle planning.
ZOLL AED Plus
The ZOLL AED Plus has a different consumable configuration and remains popular for its CPR feedback and straightforward readiness indicator. When comparing the AED Plus with newer platforms, organizations should consider both purchase price and the ongoing pad and battery schedule.
What happens after an AED is used?
After a rescue, the AED should be inspected and returned to service as quickly as possible. Used electrode pads need replacement, and other supplies may also need replenishment. The event may require data retrieval or documentation depending on the organization and circumstances.
Managing expiry dates across multiple AEDs
A single AED may be easy to check manually. Ten, 100 or 1,000 AEDs across multiple locations are different. Units can move, contacts can change and replacement dates can occur throughout the year.
TrackMyAED is designed to centralize this information. Organizations can manage device and location details, pad and battery expiry dates, readiness information, documentation and reporting in one system. Instead of relying on a spreadsheet or someone's calendar, the AED program has a structured management platform.
The answer in one sentence
Replace AED pads and batteries according to the manufacturer’s instructions and expiry dates for your exact model, and replace used pads immediately after a rescue.
Frequently asked questions
Can I use expired AED pads?
Expired pads should be replaced. An AED program should be designed to identify upcoming expiries before they become a rescue-readiness issue.
Should I keep spare pads?
Spare pads can be valuable, particularly in high-traffic locations or where replacement supplies cannot be delivered quickly after a rescue.
How can I stop expiry dates from being missed?
Use a documented inspection and management process. TrackMyAED can help centralize expiry information and ongoing program records.
