All About AED Batteries: How Often Should You Change The Batteries In Your Automated External Defibrillator

How Often Should I Change The Batteries In My AED?

The frequency of replacing the battery in an AED depends on the life expectancy of the unit and the level of use. In most cases the average lifespan of an AED battery is 3-5 years, but this will vary depending on the type of battery used, and the AED model. The manufacturer will provide specific guidelines for determining when it is time to replace your batteries. You should also check with your AED supplier for replacement procedures and maintenance recommendations. Some suppliers, like AED Advantage, send email reminders regarding device maintenance needs and battery and electrode pad expiration dates. 

How Do You Check A Defibrillator Battery?

If you don’t have a maintenance plan with your AED provider and if you are using your AED regularly, it's important to check the battery status of your device at least once a month. If you don't use your defibrillator often, or if you store your device for extended periods of time, make sure to still check your battery status frequently/monthly and to keep an up-to-date log book.

There are several ways to check the battery status of an AED:

  1. Look at the expiration date on the batteries, if the expiration date has passed, then it is time for you to replace the battery with a new one;
  2. Check the display screen on your defibrillator device. Some devices have an indicator light that will let you know when it's time to change out the batteries. For example, some devices have a red light that flashes when they need new batteries. In addition, most modern defibrillators have an audio warning or a screen that displays either “Low Battery” or “Time Remaining.” Once you see this message, it’s time to replace the batteries. Either way the battery indicator should be quite obvious; and/or
  3. Check the user manual for your specific AED and follow the instructions listed there as they may vary from product to product and manufacturer to manufacturer regarding battery expiration.

While this is a quick guide to the basics of checking your battery and maintaining your AED, there’s plenty more you can learn from looking at the user manual included with your device. And if you have any questions or concerns about your specific AED, contact the team at AED Advantage, their friendly and knowledgeable staff will be more than happy to answer any questions or concerns you may have.
