AED Battery Life: 4 Things To Know

Automated External Defibrillators, or AEDs, are amazing devices that have been proven to save lives. Using small adhesive pads with electrodes, AEDs can detect irregular rhythms in the heart and deliver a small electrical shock to restore normal function if necessary.

The brilliance of AED technology hasn’t been overlooked by state governments in the U.S. In fact, according to the National Conference of State Legislatures, every state in the country now has AED requirements of some kind for gyms, restaurants, schools, and even offices.

The fact is if you run a business of any kind, you are going to need an AED. Not only that, because of the proliferation of laws like Arizona Statute A​Z Rev Stat § 36-2263 that requires stringent AED maintenance, you’ll need to consistently ensure your AED is functioning properly.

AED Battery Life: What You Need to Know

The last thing you need is for your AED’s battery to fail during a life or death scenario. So how long do AED batteries last? When should you need to replace yours? Follow along, and we’ll delve into how long AED batteries last and explain when to replace them.

How Long Do AED Batteries Last?

There are two types of AED batteries, rechargeable batteries, and non-rechargeable batteries.

Non-rechargeable batteries are the more common type for businesses because they usually last between 3-5 years, depending on the brand, and require little to no maintenance.

Rechargeable batteries are made of Li-SO2 (Lithium Sulfur Dioxide), which means they can handle higher electrical charges making them ideal for first responders. However, rechargeable AEDs require consistent charging and monthly maintenance. On top of that, the more expensive rechargeable batteries will last, on average, only about 2 years.

When to Replace AED Batteries?

On both rechargeable and non-rechargeable batteries, you’ll find three different dates, the manufactured date, the install-by date, and the expiration date. This can be confusing when you’re trying to figure out whether or not you need to replace your batteries.

  1. Manufactured Date – The manufactured date is pretty self-explanatory, it states when the AED was manufactured. AED batteries need to be used between 5-7 years after their manufacturing date at maximum. Don’t rely on old batteries.
  2. Install-By Date – This date states the date that is the last chance you have to install the battery so it can operate with the correct expiration date.
  3. Expiration Date – This is when the battery will no longer function.

Different battery manufacturers place these three dates on a variety of locations on the batteries, so you’ll need to refer to the directions for your AED to see which is which.

Why Do You Need To Replace Batteries Regularly?

AED battery replacement isn’t to be laughed off. The fact is lives can depend on whether or not you’ve properly maintained your AED battery. That’s why state regulations across the country are so strict when it comes to AEDs.

In fact, a study analyzed data from over 40,000 AED ‘related events’ between June 1993 and October 2008 and found that of the 1,150 AED failures, 23.2% were due to battery issues. Those are startling numbers that really illustrate why staying up to date on AED battery life and maintenance is so important.

We recommend having replacement batteries on hand at all times not only to comply with local regulations but in case something goes wrong and that battery means life or death for a coworker.
