How Long Does an AED Last

How long does an AED last?

We get a lot of questions on how long an AED will last.

The answer to that question will depend on how well you take care of your AED. There is not an exact science that says an AED will last for 8 years, then you must replace it.  It may last for 8 years and we have seen some last 20+ years. 

All of our AED’s, whether you purchase a new or recertified unit, should typically last you anywhere from 10-15+ years. If it is kept in an office or storage cabinet with little usage, it will obviously last a little longer than one being banged around in the back of a police vehicle or on a fire truck.   

How will I know if there is something wrong with the AED? 

An AED will automatically perform a daily, weekly, and monthly “Self Test” and will start to chirp like a smoke detector if there is a need for servicing. Some of the AED’s will have an information button that will give you the reason for the service alarm. You will also want to perform a physical check of the AED often enough to see if the indicator button is still showing the AED is working properly or not.  If it is not chirping and the button is showing the AED is not working, it could be the battery needs to be replaced, or there may be an additional issue with the AED. 

What is the biggest issue that would cause an AED not to work properly? 

First, always replace your pads and batteries before their expiration dates.  The AED pads and batteries are usually good for 2-5 years, depending on the AED brand.  Please write the expiration dates on a check card and keep it with the AED.  Expired pads and batteries are the number one reason an AED may not work properly during an emergency. 

The other issues will be how many times the AED has been dropped, gotten wet, or been banged around.  AED’s are very durable but may start to malfunction after a lot of wear and tear.

 What do I do if the AED needs service? 

Please call us to coordinate service.  Our phone number is 1-800-441-8378.  We will try to diagnose the issue on the phone with you.  If it is determined you need to send it in for repair, we will arrange to have your AED sent to the manufacture if it is still under warranty.  If it is out of warranty, then we will have our Bio-meds assess the issue and repair the problem if it is cost effective to do so.  . 

What do I need to do to purchase an AED or replace my older unit? 

We have a professional staff trained in all makes and models of AED’s to help you determine which one is the best for you and your business.  We will advise you based on your type of business, budget, how often you may use it, and who may be using the AED (someone trained or untrained). 

We also offer special pricing for Trade-Ins, if you are replacing your older units.
