How Long Is My AED Good For? 6 things to know

Automated external defibrillators (AEDs) are a critical part of the cardiac arrest Chain of Survival. But have you wondered how long one will last? An AED is an advanced piece of lifesaving machinery with many components, including a battery pack and electrode pads. If key parts are past their recommended replacement date, your AED may not work effectively. In other words, using an expired AED during an emergency could cost someone their life.

Let's review six key questions to help you ensure yours is ready to go in an emergency. Please note that these are general guidelines. Be sure to check the owner’s manual for information on a specific model. 

1. How long does the AED last? Although an AED doesn’t have a specific expiration date, it will eventually stop working. One will typically last 10 to 15 years, depending on its use, regular maintenance, safety checks and storage. Keep your AED in a visible location. Don’t drop it or get it wet. Keep its storage temperature between 32 and 120 degrees Fahrenheit. These conditions help extend its life.

2. How long will the battery last? As a general rule of thumb, an AED battery typically lasts two to five years; however, each will include an expiration date from the manufacturer. Look for three dates printed on a battery pack: a manufacture date, an install-by date, and an expiration date. AED batteries may stop working prior to their listed expiration date. Although an AED self-checks its battery, you should routinely check too. A bad battery is a leading cause of AED failure in emergencies. 

3. How long will the electrode pads last? AED pads usually last from two years - five years before they expire. Expired AED pads may not deliver an effective shock because the adhesive gel dries out over time, causing the pads not to stick to the person, reducing the effectiveness of the shock delivered. You'll find the pads’ expiration date printed on the packaging. Be sure to replace pads in time and throw out or recycle the expired ones. Don’t keep the expired pads for use as backups. 

4. How long are AED warranties? All AED machines come with a warranty. For new AEDs, the warranty lasts up to eight years; refurbished AED warranties are shorter, usually one year. While your machine is under warranty, the manufacturer will cover repair costs or replace the device if necessary. However, you'll have to pay for repairs after the warranty expires.

5. How often should I check an AED? AEDs perform routine weekly self-checks and can alert you to any issues. Sometimes, the alert is a beeping sound; sometimes, it's a red light. Depending on your AED model, a display screen may inform you of an issue. To ensure you notice alerts, keep the machine in a visible, easily accessible location. Even though an AED performs self-checks, it’s important that you make a habit of doing monthly checks as well.

6. What should I do with expired AED? Expired AEDs and battery packs are considered hazardous waste. You'll need to take them to a hazardous waste recycling center. You may place expired electrode pads or any other accessories in the regular trash, or at your recycling center. 

That's it! Making a monthly schedule to check your AED and replace expired parts helps ensure that your AED will be ready when you need it the most.
